Overview

NSK 7002CTRSULP3 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
