Angular contact thrust ball bearings are also one kind of thrust bearings, This type of thrust bearing can be used to bear shaft and radial joint loads mainly bearing axial load, but it has higher precision, higher speed and lower noise than ordinary thrust bearings. So it mainly used in machine tools where need high precision and high speed.
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 TKW 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 reliable radial and axial support is required, together with extremely precise axial guidance of the shaft.
The TKW assortment of super-precision angular contact thrust ball bearings for screw drives can accommodate virtually any requirement placed on support bearings for screw drives. The main criteria used when selecting bearings to support screw drives are axial stiffness and load carrying capacity, running accuracy, speed, and frictional moment. Other factors to consider can be the moment stiffness of a bearing arrangement or the ability to cope with misalignment between the shaft and housing. Mounting and seal requirements also need to be considered.
super-precision angular contact thrust ball bearings for screw drives- Single direction
· Are available in the BSA and BSD series
· Are available for shaft diameters from 12 to 75 mm
· Are non-separable
· Have a 62° contact angle
Single direction bearings can be supplied as matched sets on request. However, because the standard bearings are universally matchable, TKW recommends reducing inventory by ordering single bearings only and arranging them in sets as required.

super-precision angular contact thrust ball bearings for screw drives - Double direction
· Are available in two series:
-- BEAS series
-- BEAM series
· Are greased and sealed as standard
· Are ready-to-mount
· Correspond in design to two single direction bearings arranged back-to-back
· Have a one-piece outer ring and a two-piece inner ring
· Are non-separable
· Have a 60° contact angle
· Accommodate radial loads, and axial loads in both directions
· Have an annular groove and lubrication holes in the outer ring as standard to relubricate the bearing easily and reliably when necessary
Preload (which is preset at the factory) is applied by clamping the inner ring halves on the screw drive shaft with, for example, a precision lock nut.
· 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
Depending on their series, angular contact thrust ball bearings for screw drives are fitted as standard with one of the following cages:
· A glass fibre reinforced PA66 cage, window-type, ball centred, no designation suffix
· A glass fibre reinforced PA66 cage, snap-type, ball centred, no designation suffix
As the Top Quality China Bearing manufacturer, TKW can supply the Angular Contact Thrust Ball Bearings for Screw Drives, single direction & double direction, Angular contact thrust ball bearings for screw drives, cartridge units with a flanged housing, super-precision, and also the other kinds of Super Precision Bearings.

super-precision angular contact thrust ball bearings for screw drives - Double direction
· Are available in two series:
-- BEAS series
-- BEAM series
· Are greased and sealed as standard
· Are ready-to-mount
· Correspond in design to two single direction bearings arranged back-to-back
· Have a one-piece outer ring and a two-piece inner ring
· Are non-separable
· Have a 60° contact angle
· Accommodate radial loads, and axial loads in both directions
· Have an annular groove and lubrication holes in the outer ring as standard to relubricate the bearing easily and reliably when necessary
Preload (which is preset at the factory) is applied by clamping the inner ring halves on the screw drive shaft with, for example, a precision lock nut.
· 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
Depending on their series, angular contact thrust ball bearings for screw drives are fitted as standard with one of the following cages:
· A glass fibre reinforced PA66 cage, window-type, ball centred, no designation suffix
· A glass fibre reinforced PA66 cage, snap-type, ball centred, no designation suffix
As the Top Quality China Bearing manufacturer, TKW can supply the Angular Contact Thrust Ball Bearings for Screw Drives, single direction & double direction, Angular contact thrust ball bearings for screw drives, cartridge units with a flanged housing, super-precision, and also the other kinds of Super Precision Bearings.
