SKF 7308 Series Angular Contact Ball Bearing, 40mm Inside Diameter, 90mm Outside Diameter - 7308 BECBM
This angular contact ball bearing provides axial and radial load support in rotating machinery where directional load capacity and speed are important. It is a single-row design with a parallel bore and open ends, intended for assemblies in automation, electronics and mechanical drive systems that require a Compact bearing capable of accommodating combined loads while running at elevated rotational speeds.
Features and Benefits:
• 40° contact angle increases axial load support capacity
• Brass cage reduces friction and improves heat dissipation
• Steel balls deliver consistent rolling-element hardness and life
• CN internal clearance allows precise preload and alignment control
• 50kN dynamic load rating sustains heavy operational stresses
• 13000r/min limiting speed suits high-speed rotating applications
• Brass cage reduces friction and improves heat dissipation
• Steel balls deliver consistent rolling-element hardness and life
• CN internal clearance allows precise preload and alignment control
• 50kN dynamic load rating sustains heavy operational stresses
• 13000r/min limiting speed suits high-speed rotating applications
Applications
• Suitable for spindle drives in automation equipment
• Ideal for precision motors in electronics manufacturing
• Used with gearbox shafts in industrial machinery
• Can be used for rotary encoders and servo units
• Suitable for electrical actuators requiring axial load handling

What maintenance considerations apply to this bearing in continuous operation?
Regular lubrication monitoring is essential
the open-end design permits relubrication and inspection intervals should align with operating temperature and contamination levels.
How should axial and radial loads be arranged for reliable service?
Position the bearing to take the primary axial load in the direction of the contact angle and combine with radial support elements to distribute forces across the raceways.
What installation tolerances are recommended for the bore and housing?
Use a tight interference fit on the shaft and a lighter fit in the housing to maintain alignment and control internal clearance under operating conditions.
How does the cage material affect thermal performance under high speeds?
The brass cage offers improved thermal conductivity over polymer cages, aiding temperature control at elevated rotational speeds and reducing cage distortion risks.
