Overview
FAG B71920-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.
Key features
- Super-precision running accuracy
- Low heat generation at high speed
- High spindle rigidity through preload matching
- Suitable for stable machining quality
Typical applications
- Machining center spindles
- Grinding and milling spindles
- High-speed motor spindles
- Precision inspection and processing equipment
Selection guidance
Review precision class, contact angle, arrangement, preload, lubrication method, maximum speed, and required spindle rigidity.
