FAG7212BMPUASingle-Row Angular Contact Ball Bearing – 60 mm ID, 110 mm OD, 22 mm Width, Open, 40°, Machined Brass Cage

Product Description

What this part is

FAG 7212B.MP.UA single-row angular contact ball bearing. Bore: 60 mm. Outside diameter: 110 mm. Width: 22 mm. Series: 7200 B. Base number: 7212. Open, chrome steel rings and balls. Searchable forms of the designation include 7212B.MP.UA, 7212B-MP-UA, 7212 B MP UA, 7212BMPUA and 7212.

Decoding the designation

Contact Angle: 40°, from the B position in FAG’s 7200 B series. Cage: machined solid brass window cage, from the MP position. Matching: universal, from the UA position — rings are ground so any two bearings of this designation pair up in back-to-back, face-to-face or tandem arrangement, with UA giving a small axial internal clearance in the paired set. Precision Class: ISO P0 / ABEC 1, standard tolerance.

What these specs mean in practice

A 40° contact angle is the highest-thrust angle in the angular contact range: it carries substantially more axial load than a 15° or 25° bearing of the same envelope, at lower speed. Dynamic Load Rating: 64 kN (14,387 lbf). Static Load Rating: 49.5 kN (11,128 lbf). Limiting Speed: 7,500 rpm. The machined brass window cage takes higher temperatures and higher accelerations than a pressed steel or polyamide cage, and it tolerates poor lubrication better. Mass: 1.8 lb.

Quantity and configuration

One bearing. A single 40° angular contact bearing takes thrust in one direction, so it works opposed against a second bearing, and the UA universal matching is what makes that pairing straightforward.

Fitting notes

Internal Clearance: CN, normal. This designation is clearance-set rather than preloaded, so it is not clamped up solid the way a UL preloaded pair is. The higher-shoulder side of the outer ring takes the thrust.

Interchange guidance

Equivalents at the same envelope, angle and cage: SKF 7212 BEGAM, NSK 7212B, NTN 7212B. FAG’s current designation for this bearing is 7212-B-XL-MP-UA, the X-life execution, which shares the envelope and angle and carries its own uprated load ratings. The 7212-B-XL-JP-UA and 7212-B-TVP-UA are the same envelope with pressed steel and polyamide cages respectively.
