Smooth rotation with Skf 61909-2RZ

Practical benefits

Effective double seal protection: The dual non-contact seals keep lubricant inside while keeping out contaminants to prolong service life.
Low friction high speeds: Optimized internal geometry allows you to achieve smooth running with minimal heat generation at high rotational speeds.
Reliable multidirectional load support: You can easily accommodate both radial and axial loads in either direction within a compact design.

In a nutshell

The right choise for

With the Skf 61909-2RZ deep groove ball bearing, you ensure smooth, low-friction rotation across electric motors and industrial machinery. This single-row steel bearing reliably accommodates radial and axial loads in both directions. Thanks to the dual non-contact 2RZ rubber and metal seals, lubricant stays inside while dust and contaminants are kept out, preventing heat build-up and unnecessary wear. Measuring 45X68X12 mm with a standard cylindrical bore and normal cn radial clearance, you can fit it directly onto a 45 mm straight shaft for dependable, quiet, and long-lasting operation.

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
