An NTN 7917C precision angular contact ball bearing, 85 mm bore x 120 mm outside diameter x 18 mm wide, in the 71917 / 7917 thin-section spindle envelope. It carries radial load plus thrust in one direction, with the high shoulder facing the thrust. Unit Quantity: 1 Pc, a single bearing with inner ring, outer ring, ball complement and cage, not a matched set.
7917 — single-row angular contact ball bearing, 19-series thin section, 85 x 120 x 18 mm. The 71917 form describes the same bearing.
C — contact angle 15° in NTN nomenclature.
P5 — ISO tolerance class 5, equivalent to ABEC 5.
Contact Angle: 15°. Precision Class: ISO P5 / ABEC 5. Number Of Rows: 1. Rolling Elements: Ball. Closure Type: Open, no seals or shields. Series: 79 / 71900 thin-section spindle series. Bore Type: Straight. Material: Chrome Steel. Mounting: single bearing, locates the shaft in one direction only.
Bore Diameter (d): 85 mm. Outside Diameter (D): 120 mm. Width (B): 18 mm. The bearing is open and relies on the housing for sealing.
15° equivalents on the 85 x 120 x 18 mm envelope: NSK 7917CTYNP5 and 71917CTYNP5, SKF 71917 CD/P4A (P4A, one class tighter), FAG B71917-C-T-P4S (one class tighter), Fafnir 2MM9117WICR, RHP 7917CTP5. The same envelope at 25°: NSK 7917A5TYNP5, SKF 71917 ACD/P4A and Fafnir 3MM9117WI, with more thrust capacity and less speed. The matched universally ground version of this envelope is NTN 7917CGD2GLP4. Several of these are P4 / ABEC 7, a tighter grade than P5.
Bore Diameter: 85 mm. Outside Diameter: 120 mm. Width: 18 mm.
Contact Angle: 15° (the C in the designation). Precision Class: ISO P5, equivalent to ABEC 5.
It is a single bearing with no universal-grinding or preload suffix. The matched universally ground version of this envelope is NTN 7917CGD2GLP4.
