Reliable rotation with Skf

Practical benefits

Dual metal protective shields: The two steel shields retain lubricant inside while keeping contaminants out to extend bearing service life.
Smooth high speed operation: You achieve efficient, low-friction rotation that generates minimal heat even during rapid operating cycles.
Versatile combined load handling: You easily accommodate both radial and light axial loads within compact machine spaces.

In a nutshell

The right choise for

With the Skf 638/8-2Z single-row deep groove ball bearing, you ensure smooth, dependable rotation in compact setups such as small electric motors, power tools, and precision machinery. Featuring compact dimensions of 8X16X6 mm, it fits easily into confined spaces. Dual metal shields (2Z) keep the factory-applied grease securely inside while preventing dust and debris ingress without adding unwanted friction. This low-friction design limits heat generation during high-speed operation. Capable of handling radial forces and light axial loads in both directions, this bearing gives you a robust, maintenance-free solution for your assembly and repair projects.

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
