Chemical resistant bearings 

Chemical Resistant Bearings – Custom Bearing Solutions for Corrosive Environments

Mechanical equipment used in chemical plants, food-processing facilities, cleaning systems, laboratories, outdoor equipment, and other demanding environments may be exposed to acids, alkalis, detergents, solvents, moisture, or other aggressive substances. In these conditions, conventional metal bearings may experience corrosion, surface deterioration, lubricant degradation, or shortened service life. Chemical resistant bearings can provide a more suitable solution when material compatibility is carefully matched to the actual operating environment.

Chemical resistance is not determined by one material alone. Bearing material, seals, lubrication, temperature, chemical concentration, exposure duration, load, speed, and surrounding components all influence performance.

HSIAN JI BEARING CO., LTD. is a Taiwan bearing manufacturer established in 1995. Its current product range includes plastic bearings, thrust bearings, stamped bearings, slide bearings, ball bearings, special bearings, and non-standard bearings.

HSIAN JI's official plastic-bearing information specifically states that plastic bearings can be used in environments that corrode metal bearings, including chemical plants and food-processing plants. It also lists corrosion resistance and resistance to rust as key advantages of plastic bearing products.

For customers requiring chemical resistant bearings, HSIAN JI can evaluate plastic, custom, special, and non-standard bearing projects according to drawings, materials, chemical exposure, temperature, load, speed, dimensions, and production quantity.

What Are Chemical Resistant Bearings?

Chemical resistant bearings are bearing products selected or designed to withstand exposure to specific chemicals without unacceptable degradation.

Potential chemical exposure can include:

• Acids

• Alkalis

• Detergents

• Cleaning agents

• Disinfectants

• Salts

• Industrial process chemicals

• Food-processing fluids

• Water-based chemicals

The correct bearing material depends on the exact chemical and operating conditions.

There is no single material that is resistant to every chemical.

Why Are Chemical Resistant Bearings Needed?

Chemical exposure can affect bearings in several ways.

Potential problems include:

• Corrosion

• Swelling

• Cracking

• Surface deterioration

• Seal degradation

• Lubricant breakdown

• Reduced dimensional stability

• Increased friction

• Shortened service life

Selecting the correct bearing material can help reduce these risks.

However, customers should identify the exact chemical environment before a bearing is recommended.

• Exposure time

Some chemicals can attack stainless steel aggressively.

Therefore, "stainless steel" should not automatically be considered chemically resistant under all conditions.

Plastic vs. Stainless Steel Chemical Resistant Bearings

Plastic and stainless steel have different advantages.

Plastic bearings may provide:

• Excellent resistance to certain chemicals

• No conventional metal rust

• Low weight

• Low noise

Stainless steel may provide:

• Greater mechanical strength in some applications

• Better high-load capability
