Housing, black oxide finish
The shaft height of the spindle bearings is aligned with the loose bearing units 24074 and the housings for flange nuts 24070. The housings may be screwed on from above or below and pinned with two taper pins or cylindrical pins. Double-sided stop angles facilitate the adjustment of the unit.
Fully ready-to-install solid bearing units with two-rowed pre-stressed high-accuracy bearings and a 60° pressure angle. They assimilate both radial and axial forces from both directions and, as a result of pre-stressing, provide highest rigidity, run-out, precise tool positioning and repeatability.
