angular contact thrust ball bearings for screw drives

Machine tools require screw drives that can position a work piece or machine component quickly, efficiently, and precisely. To meet these requirements, screw drives can be supported at both ends by the  super-precision angular contact thrust ball bearings. The bearings provide a high degree of axial stiffness, high axial load carrying capacity, accommodate high speeds and rapid accelerations, and offer very high running accuracy.
Angular contact thrust ball bearings for screw drives are well suited for screw drive applications, but are also beneficial in other applications, where safe radial and axial support is required, together with extremely precise axial guidance of the shaft.

With the hybrid axial angular contact ball bearings ZKLF..-HC and ZKLN..-HC, Schaeffler offers reliable solutions to the problem of “false brinelling”, known in relation to and occasionally occurring in feed axes with ball screw drives, in which balls are thought to cause indentations in the raceways. Premature bearing failures due to this type of damage, often described as fluting, can thus be avoided. If operating conditions are present, however, where there is insufficient relative motion between the rolling contact partners, the lubricant film at the rolling contact is interrupted and partial dry running occurs (direct steel/steel contact). Such operating conditions occur, for example, with small swivel angles, highly dynamic positional regulation or vibrations in a stationary state. This can occasionally lead, within a few hours, to premature bearing failure through false brinelling
