FAG B71932-E-T-P4S-UL Spindle Bearings Spindellager 160 × 220 × 28 mm

Overview

FAG B71932-E-T-P4S-UL Spindle Bearing is a super-precision angular contact ball bearing for high-speed, high-accuracy spindle positions in machine tools. It supports low heat generation, high rigidity, and controlled preload to improve machining quality and spindle stability.

It consists of precision-ground rings, high-accuracy balls, and a high-speed cage. P4S-class accuracy and matched arrangements are used to set preload, rigidity, and running accuracy, while lubrication method strongly affects performance.
