Product Description

What this part is

SNR 71907HQ16J75 super-precision angular contact ball bearing. Bore: 35 mm. Outside Diameter: 55 mm. Overall Width: 10 mm. Series: 71900. Number Of Rows: 1. Rolling Elements: Ball. Bearing Material: Bearing steel. Closure Type: Open. Bore Type: Straight.

Decoding the designation

Contact Angle: 25°. Cage Material: Phenolic. Cage Type: Machined, outer-ring land-riding. Mounting Arrangement: Universal. Running Accuracy — Radial And Axial Runout: P4. Base Number: 71907. Part Number: 71907HQ16J75.

What these specs mean in practice

Dynamic Load Rating: 13.5 kN. Static Load Rating: 9.3 kN. Limiting Speed: 30000 rpm. A 25° contact angle carries more thrust and less speed than a 15° execution on the same envelope, which suits a shaft taking a substantial axial load. The 719 extra-light section keeps the cross-section thin on a 35 mm shaft, which is what supports the high speed ceiling. Internal Clearance: N/A — the rings are universally ground for matched mounting.

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: 0.16 lbs.

Quantity and configuration

Unit Quantity: 1 Pc. A single universally ground bearing, which can run alone or be set against another universally ground 71907H in back-to-back, face-to-face or tandem.
