RHP 7211CTSUL super-precision angular contact ball bearing. Bore: 55 mm. Outside diameter: 100 mm. Width: 21 mm. Series: 7200. Base number: 7211. Single row, open, chrome steel rings and balls. Searchable forms of the designation include 7211CTSUL, 7211 C T SUL, 7211-C-T-SUL, 7211CTSULP4 and the RHP B-series form B7211X2TAULEP1.
Contact Angle: 15°, from the C position. Cage: machined laminated phenolic, outer-ring guided, rated to 120 °C, from the T position. Arrangement: single universally matchable bearing with light preload built in, from the SUL position. Precision Class: ABEC 7 / ISO P4, the RHP EP7 class.
A 15° contact angle favours speed and radial stiffness over thrust capacity, which is why it is the standard choice for machine tool spindles. Dynamic Load Rating: 46.1 kN (10,363 lbf). Static Load Rating: 36.3 kN (8,160 lbf). Limiting Speed: 13,000 rpm. The machined phenolic cage is light, self-lubricating and quiet at speed, and it tolerates oil-mist and oil-air lubrication. ABEC 7 tolerances give tighter running accuracy and lower vibration than a standard-class bearing.
One bearing. Universal matching means any two pieces of this designation can be stacked back-to-back, face-to-face or in tandem, and the ground-in light preload is achieved simply by clamping the rings.
Preload is set at the factory by the ring face grinding, so the rings are clamped solid against the shaft shoulder and housing shoulder. Because preload is ground in, this bearing carries no radial internal clearance class. Lubricant: oil.
Direct equivalents at the same angle, cage and preload: SKF 7211 CDGA/P4A, FAG B7211-C-T-P4S-UL, NSK 7211CTRSULP4. The 7211 A5 forms are a related size at 25° and carry different thrust and speed figures.
