What are the dimensions of this SKF bearing?

This ball bearing has an inner diameter of 40 mm, an outer diameter of 90 mm, and a width of 23 mm.

What does the C3 designation signify?

C3 indicates a greater radial internal clearance than normal, suitable for higher speeds or thermal expansion.

What protection does the 2RS1 seal provide?

The 2RS1 suffix means contact rubber seals on both sides, protecting internal components against dust, dirt, and moisture.

Does this bearing require lubrication before installation?

No, the bearing comes pre-greased from the factory and is maintenance-free due to its dual seals.

What loads can this deep groove ball bearing handle?

This single row deep groove ball bearing accommodates both radial and axial loads in both rotational directions.

Dependable performance with Skf engineering

Practical benefits

Effective dual rubber sealing: The integrated double seals keep grease inside while protecting you from external dust and moisture ingress.
Built for high speeds: With extra C3 radial internal clearance, your bearing easily compensates for thermal expansion during continuous operation.
Versatile combined load capacity: The single-row deep groove geometry supports both radial and axial loads in either direction with minimal friction.

In a nutshell

The right choise for

Keep your rotating shafts running smoothly under heavy operational demands with the Skf 6308-2RS1/C3 single row deep groove ball bearing. Engineered from durable steel with dimensions of 40X90X23 mm, it accommodates radial and axial loads in both directions with minimal friction. The enlarged C3 radial internal clearance easily handles thermal expansion at higher operating temperatures, preventing seizing in electric motors, pumps, and gearboxes. Thanks to the dual 2RS1 rubber contact seals, factory lubricant stays locked inside while dust, dirt, and moisture are effectively kept out, giving you dependable, maintenance-free performance.

Product description

Single row deep groove ball bearings with seals or shields are particularly versatile, have low friction and are optimized for low noise and low vibration, which enables high rotational speeds. They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than many other bearing types. The integral sealing can significantly prolong bearing service life because it keeps lubricant in the bearings and contaminants out.

Integral sealing prolongs bearing service life
Simple, versatile and robust design
Low friction and high-speed capability
Accommodate radial and axial loads in both directions
Require little maintenance
