SKF 6011-2Z/C3GJN 1 Row Deep Groove Ball Bearing - 55 mm ID, 90 mm OD

This deep-groove ball bearing is a single-row radial bearing designed to support rotational shafts in electrical, electronic and mechanical systems. It features a double-shielded configuration that reduces ingress of contaminants while permitting higher-speed operation, making it suitable for driven components in automated assemblies and precision equipment.

• Double shields reduce contamination and lower maintenance needs
• C3 internal clearance accommodates thermal expansion at speed
• Sheet-metal cage ensures stable ball guidance and reduced friction
• Dynamic capacity 29.6 kN improves load-carrying under rotation
• Static capacity 21.2 kN resists deformation under stationary loads
• Rated for up to 8,000 r/min for high-speed applications

• Suitable for motor and gearbox shaft support in automation systems
• Ideal for spindle support in small precision electromechanical devices
• Used with conveyor drive rollers in production lines
• Can be used for rotary assemblies in control-panel mechanisms

The inner ring accepts a 55mm shaft, the outer ring diameter is 90mm and the radial section width is 18mm for interference or clearance fits.

The sheet-metal cage retains the balls under centrifugal forces, improving rotational stability and reducing heat from internal friction at elevated speeds.

It is supplied with C3 internal clearance which provides extra radial play to compensate for shaft expansion and prevent preload at operating temperature.

Its construction supports high-speed rotation up to 8,000 r/min and the component can serve as a direct replacement where matching dimensions and performance are required.
