Decoding the designation

Contact Angle: 15°. Preload: Heavy. Precision Class: ABEC 7 / P4. Cage Material: Phenolic. Cage Type: Machined, outer-ring land-riding. Mounting Arrangement: Universal. Base Number: 7020. Part Number: 7020CVDUJ94.

What these specs mean in practice

Dynamic Load Rating: 74.0 kN. Static Load Rating: 80.0 kN. Limiting Speed: 9000 rpm. A 15° contact angle favours speed and radial rigidity over thrust capacity. Heavy preload gives the stiffest shaft location and the tightest running accuracy of the preload ladder, at the cost of higher running heat and a lower speed ceiling than a light-preload set. 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 speed and gives it low mass. Lubricant: grease or oil. Max Temp: 100°C. Min Temp: -30°C. Item Weight: 2.56 lbs.

Quantity and configuration

Unit Quantity: 2 Pcs. A universally ground matched pair at heavy preload, which can be set back-to-back, face-to-face or in tandem.
