Cylindrical bearing housing FKT series

fixedangular contact ball bearinglubricated

Overview
Three-row angular bearings in the FKT round-type fixed-side support unit provide high load capacity and stable durability under heavy-load or vertical ball-screw applications. The design improves support when large external forces act on the support unit, enabling higher precision and extended service life for machinery such as semiconductor equipment and medical devices.
