RHP 7211-C-T-SUL-P6 single-row angular contact ball bearing. Bore Diameter: 55 mm. Outside Diameter: 100 mm. Overall Width: 21 mm. Contact Angle: 15°. Precision Class: ABEC 3 / P6. Number Of Rows: 1. Rolling Elements: Ball. Bore Type: Straight. Closure Type: Open. Cage Material: Phenolic.
72 — ISO dimension series 02, the medium section of the angular contact range. It carries a heavier load than the 70 series at the same bore.
11 — bore code. Bore Diameter: 55 mm.
C — 15° contact angle. The carton confirms it with X2 in the RHP B-series string B7211X2TULEP3.
T — machined laminated phenolic cage.
SU — universal face control. Faces are ground so that any two bearings from the range stack back-to-back, face-to-face or in tandem without shims or ground spacers.
P6 — RHP tolerance class P6, equivalent to BS 292 EP3 and ABEC 3.
Dynamic Load Rating: 53,000 N. Static Load Rating: 40,000 N. These are the ISO 281 and ISO 76 ratings for the 7211 C envelope and are set by the internal geometry, so they hold across precision classes.
Cage Material: Phenolic. A laminated phenolic cage is light, tolerant of marginal lubrication and quiet at speed.
Item Weight: 0.603 kg (1.33 lb).
Minimum inner ring abutment diameter: 64 mm. Maximum outer ring abutment diameter: 91 mm. Maximum outer ring seating diameter: 94 mm. Chamfer r min: 1.5 mm. Chamfer r1 min: 1.0 mm.
Effective load centre a: 20.9 mm. Internal free volume: 27.8 cm3. Pitch circle diameter for lubrication jets: 72.0 mm.
Unit Quantity: 1 Pc. Mounting Arrangement: Universally ground for pairing. The carton also carries the RHP B-series designation B7211X2TULEP3.
Same 55 x 100 x 21 mm envelope at 15°, in the precision classes each maker publishes: SKF 7211 CD/P4A, FAG B7211-C-T-P4S, NSK 7211CTRSULP4, NTN 7211UCG/GNP4, Timken Fafnir 2MM211WICRSUL, Koyo 7211C/GNP4, GMN S6211 C TA P4 and SNFA E 7211 7CE1 are all P4 executions of the same size and angle. RHP B7211X2TULEP3 is this same bearing in the RHP B-series scheme.
