Decoding the designation

7213 is the ISO 72 medium series at a 65 mm bore. The C sets the contact angle at 15°. Full carton designation 7213-CTC-C78-G2, also written 7213CTCC78G2 and 7213C.

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 65 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 7213 is an ISO-pattern designation and the direct equivalents share it. Cross-Reference 1: NSK 7213C. Cross-Reference 2: NTN 7213C. Cross-Reference 3: Koyo 7213C. Cross-Reference 4: NACHI 7213C. Cross-Reference 5: SKF 7213 BECBM, the same 65 x 120 x 23 mm envelope at a 40° contact angle and therefore a related size rather than a substitution.
