The BK 25 Series Support Unit for Ball Screws (End Support Bearings) are fabricated with high precision (C5 Class) engineered bearings. These end support ball bearings are designed so that the bearing stiffness is greater than conventional bearings. All end support bearings are pre-loaded so complicated adjustments and measurements are removed making them extremely simple to install. These end support bearings are used in linear motion actuators of high precision and speed; as well, as in precision measurement equipment.
Precision block style ball screw support unit fixed side with 4 counter sunk mounting holes. Nominal ball screw sizes from 12mm to 50mm.
