Smooth rotation for industrial machinery

Practical benefits

Effective protection against debris: The dual metal shields retain lubricant inside while keeping contaminants out, giving you extended operational bearing life.
Handles versatile combined loads: The deep groove design smoothly accommodates both radial and axial loads in either direction during continuous operation.
Durable Skf steel build: Built with robust steel, it reduces friction and vibration to provide you with quiet and efficient high-speed performance.

In a nutshell

The right choise for

Keep your rotating equipment running smoothly and reliably with the Skf 6308-2Z single row deep groove ball bearing. Designed for electric motors, pumps, and gearboxes, its robust steel construction with dimensions of 40X90X23 mm efficiently accommodates both radial and axial loads in either direction. Equipped with dual metal shields (2Z), it seals factory grease inside while keeping dust and contaminants out. This lowers rotational friction, cuts down maintenance needs, and significantly extends operational bearing life at high speeds. It gives you the dependable performance you need for seamless machine maintenance, overhauls, and equipment assembly.

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
