SKF 6215-2Z Metal Shielded Single Row Deep Groove Ball Bearing 75x130x25mm

The SKF 6215-2Z double shielded deep groove ball bearing is engineered for machinery requiring a balance of substantial load-carrying capability, smooth rotation and moderate axial space. Its 75mm bore, 130mm outside diameter and 25mm width make it suitable for 75mm shaft assemblies designed around the 6215 bearing series. SKF Explorer construction incorporates a single row of balls running in deep groove raceways, enabling the bearing to accommodate radial loading alongside axial forces in either direction, within its rated limits. SKF specifies a basic dynamic load rating of 68.9kN and a basic static load rating of 49kN, providing important figures for assessing fatigue life and operating loads in motors, fans and mechanical transmission equipment.

The 2Z suffix identifies two non-contact steel shields, one on each side of the bearing. Unlike the rubber contact seals fitted to the 6215-2RS1, these shields do not rub continuously against the inner ring, helping reduce friction and heat generation during rotation. The bearing is supplied with grease lubrication, while the shields offer protection from larger particles rather than the more comprehensive contamination exclusion of contact seals. SKF lists a limiting speed of 5,300rpm and a reference speed of 10,000rpm; these are different catalogue parameters and should not be treated as interchangeable operating limits. The standard 6215-2Z has normal (CN) radial internal clearance, so check the complete designation before substituting a C3 variant. Suitable shaft and housing fits remain essential for reliable performance.

Typical Applications:

Industrial electric motor shaft assemblies
