Super Precision Bearings

Nachi-Fujikoshi bearings business started out by using the superior materials made by the company and by applying expertise in cutting and heat treatment acquired from our experience with cutting-tool manufacture. As a result, you get high speed and high precision in bearings that are durable and compact. Benefiting from our continually advancing technology, these parts are at work in automobiles, industrial machinery, and equipment in various other sectors. Everywhere, Nachi-Fujikoshi bearings contribute to better reliability.

High Speed Spindle Bearings (BNH)
  • Small Ball Angular Contact Bearing
  • Smaller machine steel balls result in higher speeds and lower temperatures than standard size balls.
  • Interchangeable with 7000 series.
  • Used for main spindle of high speed machining centers.
  • 15° contact angle.

Details

Thrust Load Angular Contact Bearings (TAH/TBH)
  • Replaces previous TAD design with a more compact design.
  • TAH design has a 30° contact angle, while TBH design provides a 40° contact angle. The smaller contact angles allow better high speed performance.
  • Mounted in pairs or triples (DB, DF, FFB)

Details

Double - row Cylindrical Roller Bearings
  • Large load capacity.
  • Large number of rollers improves rigidity.
  • Used for machine tool spindles.

Details

Double-direction Thrust Angular Contact Ball Bearings TAD series
  • Double-direction thrust bearing used in machine tool spindle.
  • High contact angles carry high axial loads.

Details

Ball Screw Support Bearings (TAB)
  • Ball screw support bearing with large axial rigidity and seals.
  • Maintenance-free with high performance lubrication grease. (The foreign substance invasion from the outside is prevented)
  • Ease of installation with pre-adjusted preload.
