An RHP 7915-T-DU-EP7 super precision angular contact ball bearing supplied as a matched duplex pair. Bore: 75 mm (2.9528 in). Outside Diameter: 105 mm (4.1339 in). Overall Width: 16 mm (0.6299 in) per bearing. Total Width: 32 mm (1.2598 in) for the pair. Series: 79, ISO 719 series, in the ISO 71915 envelope. Closure Type: open both faces. Cage Material: phenolic. Rolling Elements: steel balls, one row per bearing. Design Units: metric.
Series: 79 with bore code 15, giving a 75 mm bore and the ISO 71915 envelope. Cage Material: phenolic. Arrangement: DU, a duplex matched pair ground to stack together. Preload: light. Precision Class: EP7, equivalent to ABEC 7 in the RHP and NSK super precision scheme.
EP7 precision holds tighter running accuracy and lower vibration than a standard class bearing, which is what a machine tool spindle is bought for. Each row of an angular contact bearing takes thrust in one direction, so a duplex pair handles thrust in both directions from a single seat. Light preload keeps running torque and heat generation low while still removing play from the assembly. The phenolic cage is light and runs quietly at speed. Open faces let the assembly be lubricated by the spindle system rather than by a captive grease charge.
Unit Quantity: 2 Pcs, one matched duplex pair. Arrangement / Configuration: duplex matched pair, DU. The pair is ground as a set at the factory and stays together. Pair orientation sets whether the mounted arrangement is back-to-back, face-to-face or tandem.
MPN Variants: 7915TDUL, 7915-T-DUL, 7915 T DUL, 7915-T-DU-EP7, 7915TDULEP7. Base Number: 71915. Cross references: 71915, 7915TDU.
The ISO envelope equivalent is 71915 at light preload. The RHP B-series 7915X2 at 15° and 7915X3 at 25° share the same 75 x 105 x 16 mm envelope and are related sizes rather than direct interchanges, as are the medium and heavy preload variants of this designation.
