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 require high running accuracy.

Super Precision Cylindrical Roller Bearings

Features

  • Standard bearings that conform to ISO standards and specialized series for machine tools.
  • Double-row cylindrical roller bearings with high rigidity and single-row options for high speeds.
  • A range of NSKROBUST™ high-performance bearings for both high rigidity and ultra-high speeds.

Product List

APTSURF™ Series High-Rigidity Double-Row Cylindrical Roller Bearings

APTSURF™ Series High-Rigidity Double-Row Cylindrical Roller Bearings

APTSURF™ Series High-Rigidity Double-Row Cylindrical Roller Bearings

New materials in a new design enhance machine tool performance.

Features

  • High speeds/low heat generation
    An optimized design increases supported speeds and decreases heat generation.
  • Long life
    Grease lubrication extends service life.
  • Stable rotation
    A highly rigid PPS resin cage restricts deformation due to centrifugal force and keeps rotation stable at high speeds.

Standard Series Single-Row Cylindrical Roller Bearings

Standard Series Single-Row Cylindrical Roller Bearings

Standard Series Single-Row Cylindrical Roller Bearings

NSK's standard single-row cylindrical roller bearings conform to ISO standards.

Features

  • Long-life materials
    NSK's Z steel, a long-life bearing steel, is used as a standard material.
  • High rigidity
    High-rigidity types use a roller-guiding machined brass cage.

NSKROBUST™ Single-Row Cylindrical Roller Bearings

NSKROBUST™ Single-Row Cylindrical Roller Bearings

NSKROBUST™ Single-Row Cylindrical Roller Bearings

NSKROBUST bearings feature a highly heat-resistant PEEK cage and heat/wear-resistant SHX steel to achieve a dmN value of 2.2 million.

Features

  • Low heat generation
    An optimized design achieves low heat generation.
  • High seizure resistance
    SHX steel significantly improves seizure resistance.
  • Optimized materials for high speeds
    Heat-resistant, highly rigid PEEK resin material realizes impressive high-speed performance.

FAQ

  • What is the difference between using two single-row APTSURF bearings and using one double-row APTSURF bearing?
    • Even when the have the same bore/outside diameter dimensions, the internal design and bearing width differ between single- and double-row bearings, so their catalog limiting speeds and load ratings also differ. Because of these variations, be sure to take the dimensions surrounding the bearing into consideration as well.
  • What are the differences between the various series (APTSURF, NSKROBUST) of super precision cylindrical roller bearings?
    • APTSURF bearings are designed for precision machinery at large, while NSKROBUST bearings are specialized for ultra-high-speed applications such as machine tools.
