Uniquely Kashima

Why do we have 40% market share in Japan?
There are many reasons why our customers choose us, but what makes Kashima Bearings, Inc. a leading manufacturer is that we know plastics and tailor our plastic bearings to fulfill the needs of numerous factory environments.  Plastic bearings have their own advantages that metal bearings do not have.

Why Plastic Bearings?

– Anti-Corrosion 
– No Lubricant / Grease Required
– Nonmagnetic
– Chemically Resistant
– Electrically Insulated

Why Kashima?

High-Tech Craftsmanship: Kashima crafts bearings by hand and machine, with care and precision, relying on skills and experiences acquired over many decades. We make bearings to order for any size of lots. We listen to the customers’ needs to create the best bearing types from the best plastics for each use-case.

Many More Standard Sizes & Types: Making a mold is expensive, costing well over $10,000. Some companies demand that a customer purchase at least 100,000 pieces so they can break-even. Kashima, however, can make plastic bearings for almost all metal-standard sizes, as well as the most unique sizes and shapes.

Greater Range of Materials: Kashima can craft your bearings out of 7 different types of plastic. Injection molding only offers 1 or 2 types, but these types simply cannot offer the advantages that our range of materials provides, especially in chemical or extremely wet environments. If you are looking for just the right plastic-bearing made with world-famous Japanese care and service that can’t be found anywhere else, the answer is Kashima.


We provide you with the most suitable products for your needs in any size of orders. See our product lineup below. For any inquiries, please contact us.
