FAGB7212CB.TPA.P4.DUMAngular Contact Spindle Bearing Pair – 60 mm ID, 110 mm OD, 22 mm Width, 15° Contact Angle, ABEC 7 / P4, Phenolic Cage, Medium Preload

Product Description

What this part is:

FAG B7212-C-B-TPA-P4-DUM is a matched pair of super-precision angular contact spindle bearings from the Schaeffler B72 series. Bore Diameter: 60 mm. Outside Diameter: 110 mm. Width: 22 mm per bearing. Contact Angle: 15°. Precision Class: ABEC 7 / P4. Cage Material: Phenolic. Preload: Medium.

Decoding the designation:

B7212 — FAG spindle bearing, ISO 7212 envelope, 60 x 110 x 22 mm.

C — 15° contact angle.

TPA — machined fabric-base laminated phenolic cage.

P4 — ISO tolerance class P4, equivalent to ABEC 7.

DUM — two universally matched bearings with medium preload, mountable back-to-back, face-to-face or in tandem.

What these specs mean in practice:

Dynamic Load Rating: 56,000 N per bearing. Static Load Rating: 31,000 N per bearing. Preload Force: Medium, 996 N (Schaeffler FV M). Operating Temperature: -30 to 100 °C. Medium preload raises axial stiffness over the light setting.

Mounting data:

Shaft Shoulder Diameter: 69.5 mm. Housing Shoulder Diameter: 101.5 mm. Item Weight: 0.78 kg (1.72 lb) per bearing.

Quantity and configuration:

Unit Quantity: 2 Pcs. One universally ground matched pair.

Interchange guidance:

Fafnir 2MM212WI DUM and RHP 7212CTDUMP4 are the medium-preload matched sets in other makes. SKF 7212 CD/P4ADGC is the medium-preload set in SKF coding (DGC = medium). Current Schaeffler equivalent: B7212-C-T-P4S-UM.
