- Linear Bearing -
Shaft support blocks are used for end or intermittent support where loads are light and slight shaft deflection is not a concern. Unlike shaft support rails, blocks do not permit longitudinal passage of open-type ball bushing bearings. Shaft support blocks enable clamping of shafts, shimming is suggested for high precision applications to eliminate the effect of variations in surface of base or manufacturing tolerances between supports.
This support block is light weight and is suitable for use in linear motion applications, such as measuring systems, printing equipment, and CNC tools and so on.
