RHP 7309-E-T-DUL-P4 super-precision angular contact ball bearing. Bore Diameter: 45 mm. Outside Diameter: 100 mm. Overall Width: 25 mm. Contact Angle: 25°. Precision Class: ABEC 7 / P4. Rolling Elements: Ball. Number Of Rows: 1. Bore Type: Straight. Closure Type: Open. Bearing Material: Bearing steel. Series: 7300.
7309 — ISO series 03 angular contact ball bearing, 45 mm bore, 100 mm outside diameter, 25 mm width.
E — 25° contact angle. The current RHP and NSK code for the same angle is A5.
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.
L — light preload.
P4 — ISO precision class 4, equivalent to ABEC 7.
B7309X3TADULEP7 — the same bearing written in RHP’s B-series scheme. X3 = 25°, TA = outer-ring centred machined phenolic cage, EP7 = ABEC 7.
Cage Material: Phenolic. Cage Type: Machined, outer-ring guided. A laminated phenolic cage is light, runs against the outer-ring land and tolerates the high cage speeds of a machine-tool spindle.
Preload: Light. A light preload sets the balls against both raceways with the minimum axial force that still removes play, which keeps running temperature down at speed.
Contact Angle: 25°. A 25° angle carries more thrust than a 15° execution of the same envelope and less than a 40°, and sits where most machine-tool spindle positions are specified.
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.
