Decoding the designation

7212 is the ISO 72 medium series at a 60 mm bore. The C sets the contact angle at 15°. Full carton designation 7212-CTC-C78-G4, also written 7212CTCC78G4 and 7212C.

What these specs mean in practice

A 15° contact angle sits at the shallow end of the angular contact range. It takes thrust in one direction and puts more of the load path into the radial plane, giving higher speed capability and lower axial stiffness than a 25° or 40° bearing on the same envelope. A single angular contact bearing is normally mounted against a second one so the pair locates the shaft both ways.

Quantity and configuration

Unit Quantity: 1 Pc. One bearing per sale unit, open on both faces.

Mounting data

The 60 mm cylindrical bore seats on a plain shaft journal. Thrust passes through the high shoulder of the outer ring, so the bearing is fitted with that face toward the load and abutted against a shoulder or end cover that reacts the axial force.

Interchange guidance

The 15° C-suffix 7212 is an ISO-pattern designation and the direct equivalents share it. Cross-Reference 1: NSK 7212C. Cross-Reference 2: NTN 7212C. Cross-Reference 3: Koyo 7212C. Cross-Reference 4: NACHI 7212C. Cross-Reference 5: FAG 7212-B-TVP, the same 60 x 110 x 22 mm envelope at a 40° contact angle and therefore a related size rather than a substitution.
