Ball screw support bearings are specially designed for use in ball screw or lead screw applications. Most ball screw support bearings are angular contact bearings with a steep contact angle, such as 60°, and are available in duplex, triplex, and quadruplex configurations.
Our Super precision 60° – angular contact thrust ball bearings are developed to meet the requirements of high thrust load for ball screw support applications. The large contact angle of 60° allows high thrust loads with great stiffness.
Our Super precision 60° – angular contact thrust ball bearings are manufactured for universal ground – they can be rearranged and mounted in any arrangement. Our ball screw support bearings have a low, medium or high preload and a V-marking.
The bore and outer diameter are manufactured to precision class P4A. The axial run out is restricted to P2. These bearings have a ball guided polyamide cage which can sustain a temperature of -30 to 120 °C. Our ball screw support bearings are supplied with pre-packed grease GH62 for ready-to-use condition.
