Decoding the designation

72 — single-row angular contact ball bearing, ISO 02 heavy dimension series.

10 — bore code. Bore Diameter: 50 mm.

B — 40° contact angle.

TVP — glass-fibre reinforced polyamide window cage, ball-guided.

P5 — tolerance class P5, equivalent to ABEC 5.

UL — universally matchable, light preload. Any two bearings of this designation come up to the published preload back-to-back, face-to-face or in tandem without shims or grinding.

Searchable forms of the designation: 7210B.TVP.P5.UL, 7210-B-TVP-P5-UL, 7210BTVPP5UL, 7210-B-XL-TVP-P5-UL, 7210B.

What these specs mean in practice

Contact Angle: 40°. A steep angle moves the load line toward the axis and gives this bearing roughly twice the thrust capacity of a 15° bearing on the same envelope, at the cost of speed. It is the angle chosen for pump shafts, gearbox input shafts and screw drives carrying a heavy one-way thrust.

Dynamic Load Rating: 41,500 N. Static Load Rating: 28,500 N. Fatigue load limit: 1,970 N.

Limiting Speed: 10,300 rpm. Reference Speed: 7,600 rpm. The reference figure is the thermally-referenced speed used to size a lubrication system; the limiting figure is the mechanical ceiling of the cage and ball set.

Preload: Light. Maximum preload force per set 288 N, with an axial tolerance band of 6 µm. Operating temperature range published by Schaeffler: −30 °C to +120 °C.

A single-row angular contact ball bearing carries thrust in one direction only. Two of them locate a shaft in both directions and set the working preload.

Interchange guidance

Cross-Reference 1: FAG 7210-B-XL-TVP-P5-UL. Cross-Reference 2: SKF 7210 BEP. Cross-Reference 3: NSK 7210B. Cross-Reference 4: NTN 7210B. Cross-Reference 5: Timken / Fafnir 7210WN (related, standard precision). Cross-Reference 6: RHP 7210B. Cross-Reference 7: Koyo 7210B. Cross-Reference 8: Nachi 7210B. Cross-Reference 9: SNR 7210B.

All nine share the 50 x 90 x 20 mm envelope and the 40° contact angle. The Fafnir 7210WN is a standard-precision build, so it matches the geometry and angle but not the ABEC 5 class.
