SNR 7021HVDUJ74 super-precision angular contact ball bearing. Bore: 105 mm. Outside Diameter: 160 mm. Overall Width: 26 mm. Series: 7000. Number Of Rows: 1. Rolling Elements: Ball. Bearing Material: Bearing steel. Closure Type: Open. Bore Type: Straight.
Contact Angle: 25°. Preload: Light. Precision Class: ABEC 7 / P4. Cage Material: Phenolic. Cage Type: Outer-ring land-riding. Mounting Arrangement: Universal. Base Number: 7021. Part Number: 7021HVDUJ74.
Dynamic Load Rating: 99 kN. Static Load Rating: 93 kN. Limiting Speed: 7500 rpm. A 25° contact angle carries more thrust and less speed than a 15° execution on the same envelope, which suits a shaft that takes a substantial axial load. 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.
The 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: 2.80 lbs.
Unit Quantity: 2 Pcs. A universally ground matched pair, which can be set back-to-back, face-to-face or in tandem.
Cross-Reference 1: SKF 7021 ACD/P4ADGA. Cross-Reference 2: NSK 7021A5TYNDULP4. Both are 25° super-precision executions on the same 105 x 160 x 26 mm envelope at light preload. MPN Variants: 7021-E-T-DUL-P4, 7021-H-V-DU-J74, 3MM9121WI CR DUL, 7021A5. Harmonization Code: 8482.10.50.28.
