Thomson QS 12 MM 500, Quick Shaft, 11.99 / 12.00 mm Diameter, Class MM, Carbon Steel, 60 Rockwell C Min., 500 mm long

While Shafts may appear the same, there are significant performance differences due to the manufacturer’s selected standards, and the manufacturing processes used to achieve them. The linear inner race demands the highest levels of material cleanliness, surface topography, surface hardening, diameter, taper and roundness, surface finish and straightness to provide optimum performance, minimal maintenance and long life. Unlike common shafting, Thomson 60 Case LinearRace shafting is manufactured to the highest quality standards. Our techniques are continuously upgraded with proprietary know-how gained from over 53 years of linear bearing design and manufacture. Using 60 Case LinearRace shafting with Thomson Ball Bushing Bearings ensures optimal bearing performance and travel life.
