Smooth rotation with Skf bearing

Practical benefits

Dual side debris protection: Built with double metal shields, it retains lubricant inside while effectively shielding your mechanism from external dirt and dust.
Low friction high speeds: The low-friction design ensures smooth and quiet operation, allowing you to achieve high rotational speeds effortlessly.
Compact and versatile design: Measuring 5X11X5 mm, it allows you to accommodate radial and axial loads reliably even in tight installation spaces.

In a nutshell

The right choise for

With the Skf 638/5-2Z single-row deep groove ball bearing, you ensure smooth and reliable rotation for compact 5 mm shafts. The dual metal shields keep the lubricant inside while preventing dust and debris from entering, reducing wear and extending operational life. Its low-friction design makes it ideal for high rotational speeds in precision instruments, small electric motors, and model making. Featuring compact 5X11X5 mm dimensions and a cylindrical bore, it mounts easily onto a standard straight shaft to handle both radial and axial loads in both directions.

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
