SKF 7308 Series Angular Contact Ball Bearing, 40mm Inside Diameter, 90mm Outside Diameter - 7308 BECBJ


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.

Features and Benefits:


• 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

Applications


• 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

How does the open end design affect maintenance?


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

What bearing Interface does the parallel bore provide?


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

How does the cage material influence thermal behaviour?


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

What does the internal clearance designation mean for preload setting?


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