SKF 7308 BECBJ 1 Row Angular Contact Ball Bearing - 40 mm ID, 90 mm OD 23 mm Race Width

This angular contact ball bearing is designed to accommodate combined loads in rotating equipment where axial and radial forces act simultaneously. It is a single-row, open-ended bearing with a parallel bore and plain raceways that suits applications requiring controlled axial positioning and directional load support in mechanical and electrical assemblies.

• 40° contact angle improves axial load capacity and rigidity
• Steel ball construction enhances rolling element durability
• Steel sheet-metal cage ensures retention at higher speeds
• CN internal clearance allows predictable internal preload adjustment
• Dynamic load capacity 50 kN increases operational load endurance
• Limiting speed 10,000 r/min supports high-speed rotation demands

• Suitable for spindle assemblies in automation machinery
• Ideal for rotary electric motor shaft support in drives
• Used with precision gearboxes subject to axial thrust
• Can be used for valve actuator shafts in process equipment
• Suitable for test rigs requiring directional load control

The open end permits Visual inspection and easier re-lubrication without disassembly, aiding routine service tasks.

A parallel bore offers straightforward mounting on cylindrical shafts and simplifies axial location with external collars or shoulders.

The steel sheet-metal cage conducts heat away from the rolling elements, helping maintain dimensional stability during extended high-speed operation.

The CN clearance indicates a medium internal gap suitable for achieving light to moderate preload ranges when paired with housing fits or assembly techniques.
