Bearings for Papermaking Machines NSK
Papermaking machine bearings operating under hightemperature conditions are vulnerable to problems such as fracturing of the inner ring, which can result in work stoppages.
Bearings for Construction Machinery NSK
Construction equipment used in harsh environments risk contamination from dust, mud, and huge loads, and require a certain degree of ruggedness that is different from the requirements of a common passenger vehicle. NSK has developed bearings for such equipment.

Bearings for Swiveling Spindle Heads used in Machine Tools NSK
A series of angular contact ball bearings that has been designed specifically for swiveling spindle heads used in machine tools, such as machining centers and multi-tasking machine tools, and is suitable for high precision processing.
Features
- Ball bearings achieve high running accuracy and low torque rotation.
- High moment stiffness on a par with crossed roller bearings.
- Exclusive design of the thin cross-section profile is thinner than that of a standard angular contact ball bearing.
Ball Screw Support Bearings NSK
Highly precise angular contact thrust ball bearings for precision ball screws have been designed specifically for each application. Lineup includes both a highly rigid series and high-capacity series.
Features
- The highly rigid series for machine tool applications has been designed specifically to provide large axial rigidity and precise rotation with lower starting torque.
- The highly rigid series is available with a lubricant seal for machine tool applications.
- The high load capacity series for electric injection molding machines offers enhanced service life through the use of optimally designed ball diameter and contact angle for a higher load rating
Super Precision Cylindrical Roller Bearings NSK
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
- This lineup of bearing includes a basic series that meets ISO standards and a specified series targeting machine tools.
- 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.
- A Robust series of high performance bearings is available for applications requiring both high-speed and high-rigidity performance.
