Rolling Elements: Ball. Bearing Material: bearing steel. Closure Type: open on both faces. Bore Type: straight. Item Weight: 7.00 lbs.

Decoding the designation

Contact Angle: 15°. Preload: light. Precision Class: ABEC 7, equivalent to P4. Cage Material: phenolic laminate. Cage Type: outer-ring centred. Mounting Arrangement: universally ground. Lubricant: oil. Minimum Temperature: -30°C. Maximum Temperature: 120°C.

The carton carries this bearing in four schemes: SNR 7220 C G1 J74, FAG 7220-C-T-SUL-P4, Fafnir 2MM220WI CR SUL and NSK 7220CTYNSULP4. Searchable variants of the number include 7220CG1Q16J74, 7220 C G1 Q16 J74, 7220-C-G1-J74 and 7220C.

What these specs mean in practice

A 15° contact angle keeps the load path close to the radial plane, favouring radial stiffness and speed over thrust capacity. The 72-series section is the heavier of the two common angular contact profiles at a given bore, so this bearing carries more load than a 70-series 7020 on the same 100 mm shaft.

The laminated phenolic cage is light and absorbs oil, so it runs cooler and quieter than brass or steel at speed, and the 120°C ceiling reflects the phenolic. Centring the cage on the outer ring lets the stationary ring govern cage position, which steadies cage motion through acceleration and deceleration. ABEC 7 precision holds low radial and axial runout and gives close, repeatable shaft location. Light preload removes internal play and fixes the ball path, which is why this bearing is set by preload rather than by an internal clearance class.

Quantity and configuration

Unit Quantity: 1 Pc. One bearing from a factory three-bearing set, marked -1/3SET. It is universally ground, so it can be set against a matching bearing in any face orientation and will arrive at the designed light preload.

Interchange guidance

Cross-Reference: SKF 7220 CD/P4. Cross-Reference: NSK 7220CTYNSULP4. Cross-Reference: FAG 7220-C-T-SUL-P4. Cross-Reference: Fafnir 2MM220WI CR SUL. Harmonization Code: 8482.10.50.28. A same-envelope 7220 built at 25° is a related size rather than a substitution, because the steeper angle changes both the thrust capacity and the speed behaviour. A 7020 shares the 100 mm bore but is the lighter 70-series section, so it is a related size and not an equivalent.
