Product description of SKF Bearing BEAM 050115 C-2RSH

SKF Bearing BEAM 050115 C-2RSH. It belongs to SKF Bearing > Super-precision bearings > Angular contact thrust ball bearings for screw drives > Double direction > Super-precision. related type you may also like SKF Bearing BEAM 050115 C-2RSL

SKF double direction angular contact thrust ball bearings are designed to locate spindle shafts axially in both directions. These bearings are intended for mounting in combination with cylindrical roller bearings in the NN 30 K or N 10 K series in the same housing bore. This bearing combination simplifies machining of the housing bore.

SKF Bearing BEAM 050115 C-2RSH, Double direction angular contact thrust ball bearings are manufactured with the same nominal bore size and outside diameter as corresponding cylindrical roller bearings. However, the outside diameter tolerance of the housing washers, combined with the housing bore diameter and geometric tolerances recommended for super-precision cylindrical roller bearings under light to normal load and rotating inner ring load (Seat tolerances for standard conditions) will result in an appropriate radial clearance in the housing bore. This clearance is sufficient to prevent radial loads from acting on the thrust bearing provided that its outer ring is not axially clamped in the housing

SKF Bearing BEAM 050115 C-2RSH, SKF supplies two designs of double direction angular contact thrust ball bearings. BTM and BTW series bearings share the same bore and outside diameters, but BTM series bearings have a 25% lower bearing height, which makes them particularly suitable for compact arrangements. They do not have the same load carrying capacity and axial stiffness as bearings in the BTW series, but can operate at higher speeds.

Basic design bearings, BTW series
Consist of two single row angular contact thrust ball bearings with a 60° contact angle, arranged back-to-back. This configuration, combined with the large number of balls, enables these bearings to accommodate high axial loads in both directions and provides a high degree of system rigidity.
Offer maximum load carrying capacity and maximum system rigidity
Are available for shaft diameters from 35 to 200 mm
Are separable
Have a resulting preload within a predetermined range when the shaft washers are pressed together
Available either with steel balls or ceramic balls (Hybrid bearings)
Can be provided with an annular groove and three lubrication holes in the housing washer (designation suffix W33) on request
Can be supplied with a larger bore diameter so that they can be mounted immediately adjacent to the large diameter side of a cylindrical roller bearing with a tapered bore (e.g. BTW 60 CATN9/SP) on request. High-speed design bearings, BTM series Consist of two non-separable single row angular contact ball bearings arranged back-to-back. Offer maximum speed capability Are available for shaft diameters from 60 to 180 mm Are designed to accommodate axial loads in both directions Have a resulting preload within a predetermined range when the inner rings are pressed together Available either with steel balls or ceramic balls (Hybrid bearings) Are available with two different contact angles:
A 30° contact angle, designation suffix A
A 40° contact angle, designation suffix B
Bearings with a 30° contact angle can accommodate higher speeds while bearings with a 40° contact angle are more suitable for applications that require a higher degree of axial rigidity. According to the ISO definition, BTM series bearings are radial bearings because they have a 30° or 40° contact angle. However, since these bearings are only intended to accommodate axial loads, only their basic load rating in the axial direction is listed in the product table.
