In a nutshell

The right choise for

With the Skf 61818-2RS1, you ensure smooth and reliable rotation in compact mechanical assemblies. This single-row deep groove ball bearing easily handles both radial and axial loads in both directions within a slim 13 mm profile. Thanks to the double-sided rubber contact seals, factory grease stays securely inside while dust, dirt, and moisture are kept out. This allows your 90 mm shafts to operate smoothly with low friction and minimal vibration, delivering completely 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
