SKF Bearing Unit Insert 40 mm ID 90 mm OD UC 308

This bearing unit insert is a housed rolling element designed to support rotating shafts in industrial machinery, offering a Compact solution for mounting and alignment within pillow Block assemblies. It operates where robust radial carrying capacity and moderate rotational speed are required, suitable for integration into automation, electrical and mechanical equipment.

• Screw-type locking provides secure shaft retention and quick installation
• Dynamic capacity of 41000N enables sustained radial load handling
• Static capacity of 24000N resists heavy stationary loads
• Limiting speed of 4200rpm supports medium-speed rotating usage
• Cylindrical bore design facilitates straightforward shaft compatibility

• Suitable for conveyor drive shafts in automated production lines
• Ideal for motor coupling in electrical drive systems
• Used with gearboxes in mechanical power transmission assemblies
• Can be used for idler shafts in electronic manufacturing equipment

It is designed for a 40mm internal bore so shafts of that diameter can be accommodated without additional bushings.

The unit presents an outside diameter of 90mm, which determines the housing seat requirement.

The total width across the insert measures 52mm, which is the space needed in the housing recess.

The insert is MADE from steel, providing fatigue resistance and mechanical strength under cyclical loads.
