Smooth rotation with Skf engineering

Practical benefits

Effective seal against contamination: The double rubber seal keeps lubricant inside and protects your bearing against dirt and moisture intrusion.
Handles combined operational loads: The deep raceway geometry easily accommodates both radial and axial forces in either direction.
Compact low-friction design: With its slim 55X72X9 mm dimensions, you achieve efficient running performance within restricted installation spaces.

In a nutshell

The right choise for

With the Skf 61811-2RS1 single row deep groove ball bearing, you ensure smooth, low-friction rotation in compact installations. Thanks to its slim 55X72X9 mm dimensions and cylindrical bore, you can fit it directly onto a 55 mm shaft. The deep raceway design effortlessly handles combined radial and axial loads in both directions. The double rubber contact seal reliably keeps lubricant inside while protecting the steel bearing against dirt, dust, and moisture intrusion. This delivers dependable, low-maintenance performance for your industrial machinery, electric motors, and space-constrained drive systems.

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
