FAGAngular Contact Ball Bearing – Straight Bore, 50 mm ID, 90 mm OD, 20 mm Width, Open, 40° Contact Angle, Universal Light Preload

Product Description

What this part is

An FAG 7210-B-TVP-P5-UL single-row angular contact ball bearing. Bore 50 mm, outside diameter 90 mm, width 20 mm, open on both faces, one row of steel balls held in a glass-fibre reinforced polyamide cage, built to P5 precision and ground for universal matching at light preload.

Decoding the designation

7210 is the ISO base number in the 72 dimension series, bore code 10 giving 50 mm. In the FAG scheme B is a 40° contact angle. TVP is the glass-fibre reinforced polyamide cage. P5 is dimensional and running accuracy to ISO class 5, equivalent to ABEC 5. UL is the universal execution: the ring faces are ground so that any two bearings from the family mount back-to-back, face-to-face or in tandem and come up to light preload on their own.

What these specs mean in practice

A 40° contact angle sits at the high-thrust end of the angular contact range. It carries substantially more axial load than a 15° or 25° bearing of the same envelope and correspondingly less speed, which is the opposite trade to the FAG C execution. A single row takes thrust in one direction only, so axial location in both directions comes from pairing. P5 tightens bore, outside diameter and running accuracy over standard P0 and is the usual grade for machine-tool feed spindles, pump and gearbox thrust positions and geared drive heads. The polyamide cage is quiet and low-friction, with a continuous service ceiling of about 120 °C.

Quantity and configuration

1 Pc. Single bearing, single row, locating the shaft in one axial direction. The universal (UL) grinding means it comes up to light preload once paired with a second bearing of the same execution.

Interchange guidance

SKF 7210 BEP is the same 40°, polyamide-cage, 50 x 90 x 20 mm execution. The contact angle and precision class are part of the identity: a 7210 C at 15°, a 7210 A at 30° or a standard-precision 7210 B is a related size in the same envelope rather than an interchange, and a non-UL bearing will not come up to a defined preload as a pair.
