SKF 6305-2RS1NR 1 Row Deep Groove Ball Bearing - 25 mm ID, 62 mm OD

This deep groove ball bearing is designed to support radial and light axial loads in rotating assemblies across automation, electronics and mechanical systems. Its sealed ends shield internal rolling elements from contamination, enabling reliable operation in environments where dust or light moisture are present. The bearing suits applications requiring continuous rotation at moderate speeds while maintaining consistent internal clearance.

• 23.4 kN dynamic capacity provides high load-bearing performance
• 11.6 kN static rating resists deformation under stationary loads
• Limiting speed 7,500 r/min enables sustained rotational operation
• Sheet metal cage reduces friction and supports stable ball guidance
• Sealed ends prevent ingress and extend service intervals

• Suitable for electric motor shafts in automation equipment
• Ideal for spindle support in small machine tools
• Used with conveyor rollers in material handling systems
• Can be used for fan and blower assemblies in HVAC controls

It is designed for a cylindrical bore fit, so housings should provide accurate, smooth bores to ensure proper seating and load distribution.

The CN clearance class provides near‑normal internal play, balancing thermal expansion tolerance with minimal running noise in precision applications.

The rolling elements and raceways are steel, offering consistent hardness and wear resistance under cyclic loading.

Although sealed to reduce contamination, periodic inspection of surrounding Seals and replacement planning is advised to maintain performance over time.
