RHP7020ETDULAngular Contact Ball Bearing – 100 mm ID, 150 mm OD, 24 mm Width, Open, 25°, Light Preload, Matched Pair

Product Description

What this part is

RHP 7020ETDUL angular contact ball bearing. Bore: 100 mm. Outside Diameter: 150 mm. Width: 24 mm per bearing. Series: 70, light section. Single row of balls per bearing, open on both faces. Rolling Elements: chrome steel balls.

Decoding the designation

Contact Angle: 25°. Cage: machined laminated phenolic, outer-ring guided. Preload: light. Configuration: duplex, universally ground. The same bearing is designated 7020-E-T-DUL, B7020X3TAULEP1 and 3MM9120WI-CR-DUL.

What these specs mean in practice

A 25° contact angle carries more thrust and less speed than a 15° bearing on the same envelope. Dynamic Load Rating: 53 kN. Static Load Rating: 55 kN. Limiting Speed: 9,500 rpm. Light preload runs coolest and fastest of the three preload grades. The machined phenolic cage is light, quiet at speed, and holds oil in its fabric-base laminate.

Quantity and configuration

Unit Quantity: 2 Pcs. Universally ground faces allow the pair to be mounted back-to-back, face-to-face or in tandem, and the ground offsets set the preload when the rings are clamped. Total width of the pair: 48 mm.

Fitting notes

Preloaded sets 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 equivalents at 25°, light preload: Fafnir 3MM9120WI-CR-DUL, FAG B7020-E-T-DUL, NSK 7020A5TYNDUL. Related size: SKF 7020 ACD/P4ADGA, same envelope and angle, super precision tolerance. Related size: 7020C at 15°, same envelope, higher speed and lower thrust capability.
