Smooth rotation for compact assemblies

Practical benefits

Dual metal shield protection: The integrated steel shields keep lubricant inside while preventing dust and debris from entering the internal raceway.
Low friction at high speeds: The Skf 628/8-2Z delivers quiet operation and reduced heat generation for smooth, reliable high-speed performance.
Versatile combined load handling: You can easily support both radial and axial loads in either direction within tight mechanical spaces.

In a nutshell

The right choise for

With the Skf 628/8-2Z deep groove ball bearing, you ensure smooth, low-friction rotation on compact shafts. This single row ball bearing with dimensions of 8X16X5 mm and a cylindrical bore effortlessly handles both radial and axial loads in either direction. Thanks to the dual metal 2Z shields, factory lubricant stays securely inside while dust and debris are kept out for extended service life. Featuring standard cn radial clearance, it delivers quiet operation at high rotational speeds in small electric motors, hand tools, and model making applications.

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
