What are the dimensions of this SKF ball bearing?

This bearing has an inside diameter of 55 mm, an outside diameter of 100 mm, and a width of 21 mm.

What does the 2RS1 designation mean?

It indicates that the bearing features rubber contact seals on both sides to keep out dirt and moisture.

What does the C3 clearance mean?

C3 indicates a greater radial internal clearance than standard, ideal for higher speeds and thermal expansion.

Does this bearing require lubrication before installation?

No, it is pre-lubricated with high-grade grease at the factory and is lubricated for life.

What type of bore does this bearing have?

It features a standard cylindrical bore designed for direct mounting on a 55 mm shaft.

Smooth operation with Skf deep groove bearings

Practical benefits

Reliable double rubber sealing: The dual rubber seals retain factory lubricant while protecting internal components from dirt and moisture ingress.
Clearance for high speeds: The C3 internal clearance accommodates thermal expansion during high-speed continuous operation to prevent bearing seizure.
Multi directional load support: You can easily accommodate combined radial and axial loads in both directions with minimal rotational friction.

In a nutshell

The right choise for

With the Skf 6211-2RS1/C3 deep groove ball bearing, you ensure reliable, maintenance-free rotation for electric motors, gearboxes, and industrial drive systems. Equipped with dual rubber contact seals (2RS1), it keeps the factory lubricant securely inside while effectively locking out dust, dirt, and moisture. This single-row steel bearing measuring 55X100X21 mm with a cylindrical bore effortlessly accommodates combined radial and axial loads in both directions. The increased C3 radial internal clearance reliably absorbs thermal expansion during continuous high-speed operation, preventing bearing seizure and ensuring smooth, durable 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
