An RHP 7210CTSULP4 super-precision single-row angular contact ball bearing, 50 mm bore, 90 mm outside diameter, 20 mm wide, ground as a universal single at light preload. The 7200 series is the medium section of the super-precision angular contact range.
In the RHP scheme 7210 is the ISO 72-series section, C sets the contact angle at 15°, T is a phenolic resin cage, SU marks the ring faces as universally ground, L is light preload and P4 is ABEC 7. The carton’s second designation, B7210X2TAULEP7, restates both figures in the RHP B-series scheme: X2 is 15° and EP7 is ABEC 7.
A 15° contact angle gives the highest limiting speed and the lowest axial stiffness of the standard angular contact angles. Light preload keeps running torque and heat generation down and leaves the most speed headroom. Phenolic resin rides the outer-ring land, is light and oil-absorbent, and works to about 120 °C. ABEC 7 holds bore, outside diameter and raceway runout close enough that stacked bearings share load evenly.
1 Pc. A single universally ground bearing. Ring faces are ground so that any two pieces of the same designation mount back-to-back, face-to-face or in tandem and reach the specified light preload with the rings clamped solid.
A single-row angular contact ball bearing carries thrust in one direction only, toward the loaded shoulder. Both-direction thrust comes from a back-to-back or face-to-face pair.
The high shoulder on the outer ring sets the mounting orientation and the etched face marking identifies it. Preload on a universal bearing is developed by clamping the rings solid against the housing shoulder and the shaft nut, so seat squareness governs the running accuracy the P4 class buys.
Direct equivalents are RHP or NSK 7210C at P4 with light preload, the B-series form B7210X2TAULEP7, and the Fafnir 2MM210WI-CR-UL at 15°. A 7210E at 25° or 7210A at 30° shares the 50 x 90 x 20 mm envelope but is a related size rather than an interchange. Medium and heavy preload versions are separate parts.
