Smooth rotation with Skf engineering

Practical benefits

Dual metal shield protection: Two integrated metal shields prevent dust ingress and retain lubrication to significantly extend your bearing service life.
Low friction high speed: The optimized ball design minimizes resistance, allowing you to achieve high rotational speeds with low noise and vibration.
Versatile combined load capacity: This compact single-row bearing accommodates both radial and axial loads in either direction across your mechanical applications.

In a nutshell

The right choise for

Ensure smooth, dependable rotation on 4 mm shafts with the Skf 634-2Z single-row deep groove ball bearing. Designed with compact dimensions of 4X16X5 mm, it is ideal for small electric motors, 3D printers, precision instruments, and light cnc mechanisms. The dual metal shields keep dust and debris out while retaining factory lubrication, allowing you to run high rotational speeds with low friction and minimal vibration without relubricating. In addition, its sturdy steel construction reliably accommodates both radial and light axial loads in either direction, helping you keep your precision drives operating accurately and maintenance-free.

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
