Decoding the designation

7022 is the ISO 70 light series at a 110 mm bore. The light section keeps the outside diameter down for a given bore, which matters where the housing bore is fixed. The C sets the contact angle at 15°. Full carton designation 7022-CTC-C78, also written 7022CTCC78 and 7022C.

What these specs mean in practice

A 15° contact angle takes thrust in one direction and keeps more of the load path in the radial plane, giving higher speed capability and lower axial stiffness than a 25° bearing on the same envelope. At a 110 mm bore the 70-series section is thin, so the bearing is normally used in a pair or a set that shares the axial load and locates the shaft both ways.

Quantity and configuration

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

Mounting data

The 110 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 7022 is an ISO-pattern designation and the direct equivalents share it. Cross-Reference 1: NSK 7022C. Cross-Reference 2: NTN 7022C. Cross-Reference 3: Koyo 7022C. Cross-Reference 4: NACHI 7022C. Cross-Reference 5: SKF 7022 CD/P4A, the same envelope and angle in SKF’s super-precision build and therefore a related execution rather than a like-for-like substitution.
