Machine tools need lead screw drive to position a workpiece or machine part quickly, efficiently and accurately. In order to meet these requirements, both ends of the screw drive can be supported by SKF ultra precision thrust angular contact ball bearings. These bearings can provide high axial stiffness and axial bearing capacity, adapt to high speed and rapid acceleration, and provide very high operation accuracy. Thrust angular contact ball bearings for screw drive are well suited for screw drive applications, as well as for other applications where safe radial and axial support is required and the shaft requires extremely precise axial guidance.
High performance special bearing with mounting hole in outer ring
BSBD series high performance special bearing with mounting hole in outer ring.
The standard product adopts the two-way thrust angular contact ball bearing with back-to-back (DB) combination, integrated outer ring, sealing ring and filled with grease, which makes the operation easier.
1. Due to filling high performance grease, grease filling operation is omitted.
2. BSF series with convenient installation is also included in the product lineup. Screw holes and drawing grooves are set in the outer ring.
3. In order to meet the requirements of heavy load, high rigidity and long service life, combined products can also be provided.
