RHP7210TSULP6Angular Contact Ball Bearing – 50 mm ID, 90 mm OD, 20 mm Width, ISO 02 Series, Phenolic Cage, Light Preload, Universal Face Control, ABEC 3

Product Description

What this part is

RHP 7210TSULP6 single-row angular contact ball bearing, universally ground for matched mounting. Series: ISO 02 (72xx). Bore: 50 mm. Outside Diameter: 90 mm. Width: 20 mm. Cage Material: Laminated phenolic. Preload: Light. Precision Class: P6, ABEC 3. Rolling Elements: Ball. Bore Type: Straight.

Decoding the designation

7210 — RHP’s number for the ISO 7210 size, 50 x 90 x 20 mm, dimension series 02.

T — laminated phenolic cage.

SU — universal face control. The faces are ground so that any two bearings from the range mount together as a pair in any orientation.

L — light preload class.

P6 — RHP precision class P6, equivalent to BS292 EP3 and ABEC 3.

7210TUEP3 — the same bearing in RHP’s alternate scheme, where EP3 again gives precision class P6.

What these specs mean in practice

Bore: 50 mm. Outside Diameter: 90 mm. Width: 20 mm. Chamfer r min: 1.1 mm. Chamfer r1 min: 0.6 mm. Mass: 0.457 kg. Internal volume: 21.7 cm³. Precision Class: ABEC 3. Preload: Light.

The 02 series is the heavier of the two common angular contact sections, so this 50 mm bore arrives in a 90 mm outside diameter and carries thrust in one direction through an offset ball path. A laminated phenolic cage is light, quiet and tolerant of thin oil films. Universal face control means a second bearing of the same designation can be set back-to-back, face-to-face or in tandem straight from stock, with the light preload class arriving from the ground offset rather than from a shim pack.

Mounting data

Shaft abutment diameter d1: 57 mm minimum. Housing abutment diameter D1: 83 mm maximum. Second housing abutment diameter D2: 85 mm maximum. PCD of lubrication jets dT: 65.2 mm.

Quantity and configuration

Unit Quantity: 1 Pc. One universally ground bearing, mountable singly or as one half of a set with a second bearing of the same designation.

Interchange guidance

Same-envelope 02-series angular contact bearings at 50 x 90 x 20 mm: NSK 7210, SKF 7210, FAG 7210-B. Searchable variants of the designation: 7210TSULP6, 7210-T-SUL-P6, 7210 T SUL P6, 7210TUEP3, 7210B. Match the contact angle of the bearing being replaced, since the thrust capacity and the load centre both follow from it.
