Smooth rotation with Skf reliability

Practical benefits

Reliable protection against contamination: The double rubber seals retain lubricant inside while effectively keeping out dust and moisture.
Versatile load carrying capacity: You can easily accommodate both radial and axial loads across both rotational directions.
Low friction and quiet: Designed for minimal vibration, it ensures smooth high-speed performance with virtually zero maintenance.

In a nutshell

The right choise for

With the Skf 6304-2RSH single row deep groove ball bearing, you ensure smooth, reliable rotation on 20 mm shafts. Featuring normal radial internal clearance (CN), this bearing accommodates both radial and axial loads across both directions of rotation. Dual rubber contact seals (2RSH) retain lubricant inside while effectively shielding internal components from dust and moisture. This eliminates the need for regular re-lubrication when maintaining electric motors, pumps, gearboxes, and conveyors. With dimensions of 20X52X15 mm, this pre-lubricated steel bearing delivers quiet, low-vibration performance and dependable longevity.

Product description

Single row deep groove ball bearings with seals on one or both sides 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 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
