Super Precision Cylindrical Roller Bearings

 Overview

NSK Super Precision Cylindrical Roller Bearings are designed specifically to handle large radial loads in high-speed spindle applications that demand high running accuracy (runout) of bearing-spindle arrangements.

 Features
  1. This lineup of bearing includes a basic series that meets ISO standards and a specified series targeting machine tools.
  2. A double-row cylindrical roller bearing series is available for applications requiring high rigidity. A single-row cylindrical roller bearing series is available for applications requiring high-speed performance.
  3. A Robust series of high performance bearings is available for applications requiring both high-speed and high-rigidity performance.
     
 Product List

Highly Rigid Series of Double-Row Cylindrical Roller Bearings

New material and new design facilitate enhanced machine tool performance.
Features:

  1. High-speed performance and low heat generation
  2. Enhanced service life with grease lubrication
  3. Highly rigid PPS resin cage restricts deformation due to centrifugal force, and achieves stable rotation at high speeds.

Standard Series of Single-Row Cylindrical Roller Bearings

Basic series of NSK Super Precision Single-Row Cylindrical Roller Bearings that meet ISO standards.
Features:

  1. NSK long life Z bearing steel used as standard material.
  2. Highly rigid roller guided machined brass cage

Robust Series of Single-Row Cylindrical Roller Bearings

The highly heat-resistant PEEK cage and excellent heat resistant and wear resistant SHX steel help the bearing achieve a dmn value of 220 X 104.
Features:

  1. Optimum design for low heat generation
  2. SHX steel for improved seizure resistance, and ceramic rollers for improved reliability.
  3. High-speed performance achieved through use of heat-resistant, highly rigid, PEEK resin material
