RHP 7320-A-T-DUH-P4 super-precision angular contact ball bearing. Bore Diameter: 100 mm. Outside Diameter: 215 mm. Overall Width: 47 mm. Contact Angle: 30°. Precision Class: ABEC 7 / P4. Rolling Elements: Ball. Number Of Rows: 1. Bore Type: Straight. Closure Type: Open. Bearing Material: Bearing steel. Series: 7300.
7320 — ISO series 03 angular contact ball bearing, 100 mm bore, 215 mm outside diameter, 47 mm width.
A — 30° contact angle.
T — machined cage. The carton’s B-series string resolves it to TA: a one-piece machined laminated phenolic cage, outer-ring centred.
DU — duplex universal. The faces are ground so that any two bearings from the range mount back-to-back, face-to-face or in tandem.
H — heavy preload.
P4 — ISO precision class 4, equivalent to ABEC 7.
EP7 — the same class written in RHP’s B-series scheme, equivalent to ABEC 7.
Contact Angle: 30°. A 30° angle puts more of the load path along the shaft axis than a 15° or 25° execution of the same envelope, so a pair carries a higher thrust load and a lower radial one.
Preload: Heavy. A heavy preload gives the stiffest of the three standard settings and the most accurate shaft location, and generates the most heat at a given speed.
Cage Material: Phenolic. Cage Type: Machined, outer-ring guided. A laminated phenolic cage is light, runs against the outer-ring land and tolerates high cage speeds.
Precision Class: ABEC 7 / P4. Tighter bore, outside diameter and running-accuracy tolerances than a standard-class bearing.
Mounting Arrangement: Duplex, universally ground. Bore Type: Straight. Snap Ring Included: No.
Unit Quantity: 2 Pcs. Two pieces from a factory matched set, ground for heavy preload when mounted as a pair.
Same 100 x 215 x 47 mm envelope at a 30° contact angle: NSK 7320A, Koyo 7320 and NTN 7320. The 15°, 25° and 40° executions of the 7320 envelope split the load differently and are not a substitution.
