60 Case Standard Shafting

Thomson 60 Case® Standard Shafting

While shafts may appear the same to the untrained eye, manufacturing practices and standards significantly impact roundness, straightness, case hardness and all the qualities of shafting that Thomson customers care about.  Thomson 60 Case® is manufactured to the highest quality standards in an ISO 9000:2000 registered facility and, when used with Thomson Ball Bushing bearings, ensures optimal bearing performance and travel life.
