The SKF 6012-2Z metal shielded deep groove ball bearing provides efficient rotational support for equipment that must accommodate a 60mm shaft without the larger housing dimensions of a heavier bearing series. Its 95mm outside diameter and 18mm width make it a practical choice where radial installation space is limited. The single row deep groove raceways carry predominantly radial loads while accommodating axial forces in either direction within the bearing's rated limits. SKF specifications give a basic dynamic load rating of 30.7kN and a basic static load rating of 23.2kN, providing important reference values for calculating bearing life and assessing operating loads. Compared with the wider 6212 bearing, the 6012 offers a smaller cross-section, but the two are not dimensionally interchangeable.
The 2Z designation identifies a metal shield on each side of the bearing. Unlike rubber contact seals, these shields operate without intentional rubbing contact against the inner ring, helping reduce friction and heat generation at higher rotational speeds. They retain the factory grease and provide protection against general airborne dust, but are less suitable than contact seals where water, heavy contamination or frequent washdown is expected. SKF lists a reference speed of 15,000rpm and a limiting speed of 7,500rpm for this shielded configuration. The bearing uses normal (CN) radial internal clearance, distinguishing it from the 6012-2Z/C3 variant. Correct shaft and housing fits are essential to maintain suitable operating clearance, particularly in motor installations subject to temperature changes. Always confirm the full suffix before replacement.
Typical Applications:
Industrial electric motors and motor-driven equipment
Ventilation fans and air-handling machinery
Centrifugal pumps operating in clean environments
Industrial transmission and belt-drive assemblies
