High load with small bores

High load with small bores
The new angular-contact ball bearings from the TAC-SHR series from NSK were specially developed for use in ball screws. Although they have smaller bore sizes than the existing TAC-HR series, they boast the same load carrying capacity. This means they permit machine manufacturers to produce more compact constructions.

The main difference between the TAC-HR series and the new range is the latter's smaller bore size. This enables ball screws with smaller shaft diameters to be used at the shaft end, without the need to increase the number of ball bearings per assembly. This in turn makes it possible to realise more compact power train constructions, thus enabling designers in the machine tool industry to reduce the required installation space. 

Despite their smaller dimensions, the bearings in the TAC-SHR series have the same load ratings as those in the TAC-HR range. The new bearings are available for shaft diameters of 40 to 120mm.
