SNR7008CDUJ74Super Precision Angular Contact Ball Bearing – Straight Bore, 40 mm ID, 68 mm OD, 15 mm Width, Open, 15° Contact Angle, Universal Light Preload

Product Description

What this part is: SNR 7008CDUJ74 super-precision angular contact ball bearing. Bore: 40 mm. Outside Diameter: 68 mm. Overall Width: 15 mm. Series: 7000. Number Of Rows: 1. Rolling Elements: Ball. Bearing Material: Bearing steel. Closure Type: Open. Bore Type: Straight. Decoding the designation: Contact Angle: 15°. Preload: Light. Precision Class: ABEC 7 / P4. Running Accuracy — Radial And Axial Runout: P4. Cage Material: Phenolic. Cage Type: Machined, outer-ring land-riding. Mounting Arrangement: Universal. Base Number: 7008. Part Number: 7008CDUJ74. What these specs mean in practice: Dynamic Load Rating: 17.4 kN. Static Load Rating: 11.6 kN. Limiting Speed: 24000 rpm. A 15° contact angle favours speed and radial rigidity over thrust capacity, which suits a high-speed spindle position. Light preload holds the rings in defined contact for running accuracy while keeping heat generation low. Internal Clearance: N/A — the bearing is set by preload. Cage and lubrication: The machined phenolic cage is guided on the outer-ring land, which keeps it stable at high speed and gives it low mass. Lubricant: grease or oil. Max Temp: 120°C. Min Temp: -30°C. Item Weight: 0.42 lbs. Quantity and configuration: Unit Quantity: 1 Pc. One bearing from a factory-matched universal pair. Universally ground faces let it run alone or be set against another universally ground 7008C in back-to-back, face-to-face or tandem. Interchange guidance: Cross-Reference 1: SKF 7008 CD/P4ADGA. Cross-Reference 2: FAG B7008-C-T-P4S-UL. Both are 15° super-precision single universally matchable bearings on the same 40 x 68 x 15 mm envelope at light preload. MPN Variants: 7008-C-T-DUL-P4, 7008-C-DU-J74, 2MM9108WI CR DUL.
