SKF 6304-2RSHNR 1 Row Deep Groove Ball Bearing - 20 mm ID, 52 mm OD

This deep-groove ball bearing is a sealed single-row solution designed to support radial and moderate axial loads in rotating equipment. It is intended for use where compact, maintenance-friendly bearings are required within industrial motors and automation assemblies. The component offers sealed protection suitable for continuous operation at elevated rotational speeds and is constructed from hardened materials for prolonged service life.

• Dynamic capacity 16.8 kN delivers higher load handling
• Limiting speed 9,500 r/min enables high-speed applications
• Sheet-metal cage reduces friction and rotational heat
• Sealed end type minimises contamination ingress
• Internal clearance CN supports controlled shaft positioning

• Suitable for Compact motor spindles in automation systems
• Ideal for small electric motors in electronic devices
• Used with gearbox input shafts in industrial drives
• Can be used for conveyor idler rollers in production lines

The bearing uses a cylindrical bore so it mounts directly onto a straight, accurately sized shaft journal without a tapered adaptor.

Rolling elements and races are steel, providing fatigue resistance and durability under cyclic loading.

The sheet-metal cage maintains ball spacing with minimal mass, reducing centrifugal forces at high speeds and improving stability.

The static capacity is 7.8 kN, which defines the bearing’s allowable load when not rotating and aids selection for start–stop conditions.
