Smooth rotation with Skf

Practical benefits

Dual metal shield protection: Integrated shields keep grease inside while blocking external contaminants to prolong the bearing service life.
Optimized C3 radial clearance: You achieve smooth operation even when thermal expansion occurs at higher operating speeds and temperatures.
Dynamic bidirectional load support: The sturdy single row design accommodates both radial and axial forces across diverse industrial applications.

In a nutshell

The right choise for

With the Skf 6308-2Z/C3GJN deep groove ball bearing, you ensure smooth and reliable rotation for shafts in electric motors, drives, and industrial machinery. Its dual 2Z metal shields retain lubricant while effectively keeping dust and contaminants out, delivering a longer service life with minimal maintenance. The C3 internal radial clearance provides the necessary space to accommodate thermal expansion and tight interference fits without risk of seizure. Featuring a 40 mm cylindrical bore, a 90 mm outside diameter, and a 23 mm width, this single row steel bearing effortlessly handles both radial and axial loads in both directions to keep your equipment running steadily.

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
