SKF 7309 Series Angular Contact Ball Bearing, 45mm Inside Diameter, 100mm Outside Diameter - 7309 BEP

This angular contact ball bearing is designed to support combined radial and axial loads in precision rotating equipment where directional stiffness and alignment are required. It is a single-row, open-ended unit intended for high-speed machine spindles and driven shafts, offering a 40° contact geometry for effective thrust transmission and axial location in paired arrangements.

Features and Benefits:

• 40° contact angle gives enhanced axial load capacity
• Steel rolling elements deliver consistent contact performance
• Non-metallic cage reduces friction and damping under rotation
• CN internal clearance ensures controlled preload and axial positioning
• Dynamic load rating 55.9 kN provides sustained operational load capacity
• Limiting speed 8,000 r/min enables high-speed spindle applications

Applications

• Suitable for high-speed machine spindles requiring axial support
• Ideal for automation rotary actuators with combined loads
• Used for servo motor shafts in precision motion systems
• Can be used for gearboxes where axial location is required

What bore and outer diameters does it use for mounting?

The inner diameter measures 45mm and the outer diameter is 100 mm, enabling common shaft fits and housings.

How does the race design affect contact behaviour?

The plain race profiles guide the balls with continuous contact areas suitable for sustained axial and radial load sharing.

What clearance class is provided and why does it matter?

The clearance is CN, a standard normal internal clearance that simplifies achieving correct preload in paired or single-bearing arrangements.

Which materials are used for load-bearing components?

Balls are MADE from bearing-grade steel and the cage is a non-metallic polymer to balance strength and reduced drag.

What static load can be expected when stationary under load?

The static load rating is 37.5 kN, providing a reference for allowable non-rotational loads during assembly or standstill.
