Anticorrosive, chemical resistant, nonmagnetic and lubrication-free, Kashima plastic bearings are uniquely designed to meet the varying and long-term demands of a wide range of applications.
Kashima Bearings Inc., a manufacturer of plastic components in Japan, is known for hand-machined plastic bearings. Dimensional tolerance, linear thermal expansion and water absorption characteristics of plastics are thoroughly evaluated with each design.
Based on years of experience, Kashima selects the best-suited materials for bearings to the users’ requirements, including super-engineering plastic. For example, PTFE or UHMWPE is selected for chemical environments due to their corrosion resistance and non-absorbency. PEEK and PPS are used for various applications for their high chemical and heat resistance and dimensional stability.
The unique properties of Kashima plastic bearings make them suitable for use in a range of applications, including the wet environment of the food-processing industry. As Kashima plastic bearings do not require grease or oil, they meet the clean-room demands of the semiconductor industry, and they do not rust when exposed to chemical cleaners or rinsing water in semiconductor applications. The non-magnetic design of Kashima plastic bearings also makes them suitable for use in medical equipment or control units where the development of any static and noise should be prevented.
