What are the dimensions of this SKF ball bearing?

This bearing has a 45 mm inside diameter, a 100 mm outside diameter, and a width of 25 mm.

What does the 2RS1 suffix mean?

The 2RS1 designation indicates that the bearing has rubber contact seals on both sides to keep dirt and moisture out.

What does the C3 clearance rating mean?

The C3 designation indicates a greater internal radial clearance than standard, ideal for thermal expansion or high speeds.

Does this deep groove ball bearing require lubrication before use?

No, this bearing comes pre-greased from the factory and is lubricated for life.

What types of loads can this bearing accommodate?

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

Smooth rotation with 6309-2RS1/C3

Practical benefits

Sealed against harmful contaminants: Rubber contact seals on both sides retain lubricant effectively and block dirt and moisture, minimizing your ongoing maintenance needs.
Greater internal clearance C3: With C3 radial internal clearance, you accommodate thermal expansion during demanding high-speed and elevated-temperature operations without friction spikes.
Combined radial axial support: You reliably support both radial and axial loads in either direction across a broad range of heavy-duty machinery.

In a nutshell

The right choise for

Keep your machinery operating smoothly and reliably with the Skf 6309-2RS1/C3 single row deep groove ball bearing. Designed with dual rubber contact seals, it effectively retains lubricant while blocking out dust and moisture for maintenance-free operation. The increased C3 radial internal clearance prevents binding by easily accommodating thermal expansion at high speeds and under heavy continuous loads. Measuring 45X100X25 mm, this robust steel bearing reliably supports both radial and axial forces across electric motors, industrial pumps, fans, and conveyor systems to maximize equipment lifespan.

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
