Kashima: Plastic Bearings

Kashima Bearings, Inc., formed in 1961 has specialized in plastic bearings for decades. Unlike those companies that rely on injection-molded plastics, Kashima’s techniques allow them to craft what you need quickly and precisely via machining.

Kashima’s plastic bearings are manufactured with the highest class of materials and precision possible. Dimensional tolerance, linear thermal expansion, and water absorption characteristics of plastics are thoroughly evaluated and factored into all designs. The products are developed and manufactured to have the highest quality for performance, functionality, and durability to satisfy the most demanding customers worldwide.
