Product Description

What this part is

SNR 7008HUJ74 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: High carbon chrome steel. Closure Type: Open. Bore Type: Straight.

Decoding the designation

Contact Angle: 25°. Preload: Light. Precision Class: ABEC 7 / P4. Cage Material: Phenolic. Cage Type: Machined, outer-ring land-riding. Mounting Arrangement: Universal. Base Number: 7008. Part Number: 7008HUJ74.

What these specs mean in practice

Dynamic Load Rating: 21.6 kN / 4856 lbf. Static Load Rating: 18.3 kN / 4114 lbf. Limiting Speed: 24000 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. 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: -40°C. Item Weight: 0.42 lbs.

Quantity and configuration

Unit Quantity: 1 Pc. A single universally ground bearing, which can run alone or be set against another universally ground 7008H in back-to-back, face-to-face or tandem.
