Non standard bearings

Non Standard Bearings – Custom Bearing Solutions from Taiwan

Standard bearings are widely available in established sizes and configurations, but not every machine, product, or mechanical assembly can use a standard bearing. Special shaft dimensions, restricted installation space, unique mounting structures, discontinued components, or original equipment designs can create the need for non standard bearings.

Non standard bearings are developed to meet application requirements that cannot be satisfied by conventional catalogue products. They may feature customized dimensions, special external structures, unique mounting arrangements, different materials, or other application-specific characteristics.

HSIAN JI BEARING CO., LTD. is a bearing manufacturer based in Taiwan. Established in 1995, we develop and manufacture bearing products for a wide range of mechanical applications. Our product categories include ball bearings, plastic bearings, thrust bearings, stamped bearings, slide bearings, special bearings, and non-standard bearings.

For customers requiring non standard bearings, HSIAN JI can evaluate projects according to engineering drawings, physical samples, dimensions, materials, application requirements, and production quantities.

What Are Non Standard Bearings?

Non standard bearings are bearing products that differ from conventional catalogue sizes, structures, or specifications.

A standard bearing is normally manufactured according to established dimensions and can be selected using a catalogue number.

A non-standard bearing is generally required when the application has unique requirements.

These can include:

Special inner diameter
Special outer diameter
Custom width
Unique overall dimensions
Special flange dimensions
Unusual external geometry
Custom mounting features
Limited installation space
Special material requirements
Application-specific structures

The exact design depends on the customer's mechanical system and operating requirements.

Why Are Non Standard Bearings Needed?

Machines and products are not always designed around standard bearing dimensions.

In some applications, engineers have limited space available and cannot modify the shaft, housing, frame, rail, or surrounding components.

In other situations, an existing machine may use a bearing that is no longer readily available.

Non standard bearings can provide a solution for applications involving:

Custom machinery
OEM equipment
Existing mechanical assemblies
Special product designs
Restricted installation spaces
Older machines
Imported equipment
Discontinued bearing models

Instead of redesigning an entire mechanical system, developing a bearing according to the required dimensions may provide a practical alternative.

Non Standard Ball Bearings

Standard ball bearings are available in many sizes, but customized applications may require dimensions or structures that do not correspond to conventional catalogue models.

Non-standard ball-bearing requirements may involve:

Custom bore diameter
Custom outer diameter
Special width
Different external structure
Unique mounting configuration
Application-specific dimensions

Customers should provide shaft dimensions, housing dimensions, load, speed, installation information, and operating conditions when requesting development.

HSIAN JI manufactures ball bearing products and can evaluate customized requirements according to manufacturing feasibility.

Non Standard Plastic Bearings

Plastic bearings can provide useful characteristics for specialized mechanical applications.

Depending on material and design, potential advantages can include:

Lightweight construction
Corrosion resistance
Reduced noise
Moisture resistance
Design flexibility

A non-standard plastic bearing can also be developed around unique dimensions or mechanical structures.

Customers should provide information about temperature, load, movement, moisture, chemicals, and environmental conditions so that material and design requirements can be properly evaluated.

Non Standard Thrust Bearings

Thrust bearings are primarily designed to support axial loads.

A standard thrust bearing may not fit a specialized mechanical assembly because of its inner diameter, outer diameter, thickness, or surrounding structure.

Custom requirements may therefore involve:

Special inner diameter
Special outer diameter
Custom thickness
Limited installation space
Unique shaft dimensions
Application-specific configurations

Customers should provide axial-load information, operating speed, dimensions, materials, and quantity for evaluation.

Non Standard Slide Bearings

Slide bearings support and guide sliding or linear movement.

Customized slide bearings may be necessary when standard products cannot match the rail, guide, bracket, frame, or surrounding mechanical structure.

Potential applications include:

Machinery
Automation equipment
Conveyors
Sliding doors
Windows
Furniture systems
Drawers
Mechanical guides
Specialized equipment

Assembly drawings can be especially useful when developing non-standard slide bearings because they show the relationship between the bearing and surrounding components.

Non Standard Stamped Bearings

Stamped bearings can be developed for various mechanical, hardware, equipment, and OEM applications.

A customized stamped bearing may require special:

Dimensions
Metal structures
Mounting features
External geometry
Installation arrangements

Customers can provide engineering drawings or physical samples for evaluation.

The manufacturing method depends on geometry, materials, quantity, and application requirements.

Custom Size Non Standard Bearings

One of the most common reasons for developing non standard bearings is the need for special dimensions.

For example, a customer may have an existing shaft diameter that cannot be changed, while the available housing space is also fixed.

A standard bearing may have the correct bore but an unsuitable outer diameter or width.

Custom-size development can potentially address combinations of dimensions that are unavailable from standard products.

Customers should clearly identify all critical dimensions on their technical drawings.

Non Standard Bearings from Engineering Drawings

Engineering drawings provide one of the best starting points for custom bearing development.

A drawing can communicate:

Inner diameter
Outer diameter
Width
Overall geometry
Materials
Mounting features
Critical dimensions
Required tolerances

Customers can provide 2D technical drawings, 3D CAD models, and assembly drawings.

Assembly drawings are particularly useful because they help show how the bearing interacts with shafts, housings, rails, rollers, brackets, wheels, and other components.

Non Standard Bearings from Physical Samples

Sometimes the original engineering drawing is unavailable.

This frequently occurs when replacing components from older machinery, imported equipment, discontinued products, or specialized mechanical systems.

In these situations, a physical bearing sample can provide valuable dimensional and structural information.

HSIAN JI can develop and manufacture samples according to different customer requirements.

However, a sample does not always reveal the original material specification, tolerance, load rating, or operating requirements.

Customers should therefore provide as much additional information as possible.

Replacement Non Standard Bearings

Replacement is an important application for non-standard bearing development.

A machine may still operate effectively while one particular bearing becomes difficult to source.

Possible reasons include:

Original manufacturer discontinued the product
Original supplier is no longer available
Bearing model has become obsolete
Machine is relatively old
Bearing was originally custom-made
Imported replacement parts are difficult to obtain

When no standard replacement fits the existing shaft and housing, custom development may be worth evaluating.

Obsolete Bearing Replacement

Industrial equipment can remain in operation for many years.

During that period, some original components may become obsolete.

Replacing an entire machine because one bearing is unavailable may be costly.

Where technically and commercially feasible, developing a replacement non-standard bearing based on the original component and application requirements may provide another option.

Customers should provide the original sample, available drawings, machine information, dimensions, and operating requirements.

Non Standard Bearings for OEM Products

OEM manufacturers frequently create products with unique mechanical structures.

Designers may not want to change the entire product simply to accommodate a standard catalogue bearing.

A non-standard bearing can potentially be developed around the OEM product.

OEM customers should provide:

Engineering drawings
Assembly drawings
Materials
Critical dimensions
Load and speed information
Initial order quantity
Estimated annual demand
Quality requirements
Packaging requirements

This information helps evaluate both technical and production feasibility.

Prototype Non Standard Bearings

Prototype development is particularly useful for customized bearing projects.

Before mass production, a prototype can be installed into the customer's actual assembly to evaluate:

Dimensions
Fit
Installation
Movement
Mechanical compatibility
Assembly relationship
Functional performance

If changes are necessary, they can be evaluated before regular production.

This can reduce the risk associated with producing large quantities of an unverified custom design.

Low Volume Non Standard Bearings

Not every custom bearing project begins with mass production.

Some customers require bearings for:

Prototype equipment
Product development
Specialized machinery
Replacement applications
Initial market testing
Small production programs

Production feasibility and quantity requirements depend on bearing design, materials, tooling, and manufacturing processes.

Customers should provide both the initial quantity and expected future demand when requesting a quotation.

Non Standard Bearings for Industrial Machinery

Industrial machinery is one of the areas where non-standard bearings can be especially useful.

Special machinery may have unique:

Shaft dimensions
Roller dimensions
Housing dimensions
Installation spaces
Mechanical movements
Mounting configurations

Customers should provide complete application information so that the bearing can be evaluated within the context of the entire mechanical system.

Non Standard Bearings for Conveyor Systems

Conveyor systems use bearings in rollers, shafts, wheels, guides, and moving components.

Customized conveyor designs may require bearings that do not correspond to standard catalogue products.

Important considerations can include:

Roller dimensions
Shaft dimensions
Load
Speed
Operating environment
Continuous operation
Mounting configuration

HSIAN JI's non-standard bearing products are used across applications including conveyor systems and machinery.

Non Standard Bearings for Specialized Applications

Depending on design and specifications, non-standard bearing solutions may be relevant to:

Industrial machinery
Conveyor systems
Medical equipment
Office equipment
Packaging equipment
Furniture
Sliding systems
Hardware products
Transportation products
Bicycles
Scooters
Skates
Specialized OEM products

Every application has different technical requirements.

The bearing should therefore be evaluated according to the actual product rather than simply selecting the closest available standard size.

Quality Control for Non Standard Bearings

Quality management is especially important for customized bearings because the product may be manufactured specifically for one customer's application.

Quality activities can include:

Raw material control
Manufacturing process control
Dimensional inspection
Product testing
Finished-product inspection
Production monitoring
Packaging inspection
Continuous improvement

HSIAN JI describes its quality-assurance process as covering raw-material control, manufacturing-process control, inspection and testing of finished products, and continuous improvement.

Approved drawings and samples can also provide references for repeat production.

From Non Standard Bearing Prototype to Production

A custom project may involve the following stages:

Customer requirement review
Drawing or sample evaluation
Application analysis
Product concept development
Material selection
Prototype manufacturing
Testing and verification
Design modification if required
Production preparation
Trial production
Regular production
Inspection and shipment

HSIAN JI's published development process includes concept design, product design, prototyping, testing and verification, production preparation, and trial/mass production.
