A single super-precision angular contact ball bearing, RHP 7210ETSULP4, in the ISO 7210 envelope. Brand: RHP (NSK-RHP). MPN: 7210ETSULP4. Bearing type: super-precision angular contact ball bearing, single row, universally ground. Number of rows: 1. Bore type: Straight. Rolling elements: Balls. Seal type: Open.
Bore diameter d: 50 mm (1.9685 in). Outside diameter D: 90 mm. Width B: 20 mm. Chamfer r min: 1.1 mm. Chamfer r1 min: 0.6 mm. Shaft abutment diameter d1 min: 57 mm. Housing abutment diameter D1 max: 83 mm. Outer ring abutment diameter D2 max: 85 mm. Internal volume: 21.7 cm3. PCD of lubrication jets: 65.2 mm. Mass: 0.457 kg (1.008 lb).
Dynamic load rating Cr: 41,000 N (41.0 kN). Static load rating C0r: 30,500 N (30.5 kN). Limiting speed: 22,600 rpm oil/air; 14,000 rpm grease. Effective load centre a: 26.3 mm. Maximum operating temperature: 120 °C.
Precision class: P4 (ISO Class 4); ABEC 7; RHP class code EP7. Contact angle: 25°. Cage type: machined, outer ring land riding. Cage material: laminated phenolic resin. Preload: Light (L). Face control: SU, single universal face control. Arrangement: single, universally ground (SU). Ring and ball material: carbon chrome bearing steel, BS970 534A99 / 535A99 or SAE 52100. Snap ring included: No. The bearing is preload-set at manufacture rather than clearance-set.
In 7210ETSULP4: 7 is a single-row angular contact ball bearing, 2 is ISO dimension series 02, 10 is the bore code for 50 mm, E is the legacy RHP 25° contact angle equal to the current A5 code, T is the machined laminated phenolic cage guided on the outer ring, SU is single universal face control, L is light preload and P4 is ISO Class 4, equal to ABEC 7. The B-series form B7210X3TAULEP7 agrees: X3 gives 25° and EP7 gives the P4 class.
A single-row angular contact bearing carries radial load together with thrust in one direction only. Axial location in both directions comes from mounting a second bearing opposed to this one.
Shaft abutment diameter d1 min: 57 mm. Housing abutment diameter D1 max: 83 mm. Outer ring abutment diameter D2 max: 85 mm. Maximum fillet radius at the abutment: 1.1 mm on the main faces and 0.6 mm on the front faces. Effective load centre a: 26.3 mm from the bearing face. Internal volume for lubricant fill: 21.7 cm3. PCD of lubrication jets: 65.2 mm.
The rings are universally ground, so two bearings of this designation and preload class pair back-to-back, face-to-face or in tandem and reach the specified light preload as ground.
RHP super-precision designations cross-reference directly to NSK, which acquired RHP and continued the numbering. Matching 25° light-preload universal bearings: NSK 7210A5TRSULP4, where A5 is the NSK code for 25° and TR the phenolic cage, and Fafnir 3MM210WI CR SUL. Base number: 7210. MPN variants: 7210ETSULP4, 7210-E-T-SUL-P4, 7210 E T SUL P4.
