RHP 7211CTDULP4-1/2PR super-precision angular contact ball bearing. Series 7211, 55 mm bore, 100 mm outside diameter, 21 mm width. Contact Angle: 15°. Cage Material: Laminated phenolic, machined, outer-ring guided. Precision Class: P4 (ABEC 7). Bore Type: Straight. Closure Type: Open. Number Of Rows: Single row. Rolling Elements: Steel balls. Material: Chrome steel. Design Units: Metric. Base Number: 7211. Item Weight: 1.35 lbs.
The -1/2PR suffix marks one bearing, half of a factory-ground duplex pair. Unit Quantity: 1 Pc. Two matched halves from the same original set reproduce the specified duplex preload. Preload: Light (L). Mounting Arrangement: Universal.
7211 is the ISO 72-series angular contact envelope, 55 x 100 x 21 mm. C denotes a 15° contact angle. T is the machined, outer-ring-guided phenolic cage. DUL is the duplex-universal light-preload grinding standard. P4 is ISO tolerance class 4, equivalent to ABEC 7.
A 15° contact angle carries less thrust than a 25° or 30° angle and supports higher speed and closer running accuracy. Light preload gives the lowest heat generation and highest speed capability of the duplex preload classes. Dynamic Load Rating: 66.5 kN. Static Load Rating: 40.0 kN. Limiting Speed: 14,900 rpm grease, 18,000 rpm oil-air. Max Temp: 120 °C. Min Temp: -30 °C. Lubricant: Oil. Harmonization Code: 8482.10.50.
Equivalent designations include 7211X2TADULEP7 and the world-number form 7211C-T-P4S-DUL. Cross-references: FAG B7211-C-T-P4S-UL and SKF 7211 CDGA/P4A.
