Smooth rotation for industrial machinery

Practical benefits

Effective protection against contaminants: The dual rubber contact seals retain lubricant inside while protecting your bearing against dirt, dust, and moisture.
Accommodates increased thermal expansion: With C3 internal radial clearance, your setup operates smoothly at high speeds without binding during temperature increases.
Combined radial and axial loads: This single row deep groove ball bearing handles bidirectional forces simultaneously with minimal friction and low maintenance.

In a nutshell

The right choise for

With the Skf 6306-2RS1/C3 deep groove ball bearing, you ensure smooth and reliable rotation for shafts in electric motors, pumps, and industrial machinery. Dual rubber contact seals keep the factory grease securely inside while protecting against dust, dirt, and moisture ingress for maintenance-free operation. Thanks to the increased C3 radial internal clearance, your equipment effortlessly accommodates thermal expansion at higher operating speeds without seizing. Measuring 30X72X19 mm, this single row steel bearing handles both radial and axial loads in either direction with minimal rotational friction.

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
