RHP7220CTRDULP3Angular Contact Ball Bearing – 100 mm ID, 180 mm OD, 34 mm Width, Open, 15°, Light Preload, Universally Ground Single

Product Description

What this part is

RHP 7220CTRSULP3 angular contact ball bearing. Bore: 100 mm. Outside Diameter: 180 mm. Width: 34 mm. Series: 72, medium section. Single row of balls, open on both faces. Rolling Elements: chrome steel balls.

Decoding the designation

Contact Angle: 15°. Cage: machined laminated phenolic, outer-ring guided. Preload: light. Configuration: single bearing, universally ground. The same bearing is designated 7220-C-TR-SUL-P3 and 2MM220WI-CR-SUL.

What these specs mean in practice

A 15° contact angle favours speed and radial stiffness over thrust capacity. The 72 medium section carries a higher load than a 70 light-section bearing on the same bore. Dynamic Load Rating: 157 kN. Static Load Rating: 127 kN. Limiting Speed: 8,300 rpm. An outer-ring guided phenolic cage runs quietly and holds oil in its fabric-base laminate.

Quantity and configuration

Unit Quantity: 1 Pc. Universally ground faces allow this bearing to be stacked with another of the same designation back-to-back, face-to-face or in tandem, with the ground offsets setting the preload when the rings are clamped.

Fitting notes

Preloaded bearings are supplied without internal clearance, so Internal Clearance is N/A. Clamping is against the ground faces of both rings. Phenolic cages are rated to 120 °C and suit oil or grease lubrication.

Interchange guidance

Same-spec equivalent at 15°, light preload, single universal: Fafnir 2MM220WI-CR-SUL. Related size: 7220CTDUL, the duplex pair on the same envelope. Related size: 7220A5 at 25°, same envelope, different thrust and speed capability.
