sets (DB). Rear side: Ultra high-speed single row cylindrical roller bearing. (In case of angular contact ball bearings, either position or constant pressure preload is applicable). Spindles with this arrangement are suited for ultra high speed operation and use position preload. They achieve higher radial and axial rigidity.

Angular Contact Ball Bearings | Ball Bearings | Products | NSK Glob

The NSK range of angular contact ball bearings has been designed to meet the increasingly demanding requirements of original equipment manufacturers. These bearings have a contact angle so that they can sustain significant axial loads in one direction together with radial loads. Furthermore, since an axial component

Radial loads and axial loads in one direction can be sustained. Since two bearings share the axial load, this arrangement is used when the load in one direction is heavy.

Ball Screw Support Bearings | Products | NSK Glob

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. 1. The highly rigid series for machine tool applications has been designed specifically to provide large axial rigidity

DF and DB duplex bearings are capable of taking radial loads and axial loads in either direction. Type DT is used when there is a strong axial load in one direction and it is necessary to impose the load equally on each bearing. Duplex Bearings. Double-row angular contact ball bearings are basically two single-row angular
