Angular contact thrust ball bearings for screw drives are divided into the "BEAS series" and "BEAM series".
Machine tools require screw drives that can position a workpiece or machine component quickly, efficiently, and precisely. To meet these requirements, screw drives can be supported at both ends by super-precision angular contact thrust ball bearings. The bearings provide a high degree of axial stiffness and 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 reliable radial and axial support is required, together with extremely precise axial guidance of the shaft.
BEAM series bearings
- Correspond in design to BEAS series bearings except that the outer ring is much thicker and equipped with through holes for attachment bolts
- By bolting directly onto an associated component, the design and mounting process is simplified.
- Have M6 threaded holes for grease fittings on one side face and the bearing outside surface to enable relubrication, if required.
- The holes are plugged on delivery with grub (set) screws. The side face with the threaded hole should be mounted opposite the machine wall.
- Have an annular groove on their outside surface that can be used to dismount the bearing from its seat on the screw drive shaft
