The SKF 6017-2Z shielded deep groove ball bearing provides radial shaft support for industrial machinery requiring an 85mm bore without the larger outside diameter of a 6217 or 6317 bearing. Its 130mm outside diameter and 22mm width make it suitable for assemblies where radial installation space is an important design constraint. The single row deep groove raceway construction supports substantial radial loading together with axial forces in either direction, within the bearing's rated limits. SKF specifies a basic dynamic load rating of 52kN and a basic static load rating of 43kN, with a fatigue load limit of 1.76kN. These figures help engineers assess bearing service life, peak loading and suitability for continuous mechanical operation.
The 2Z designation indicates a non-contacting steel shield on each side rather than rubber contact seals. These shields help retain the factory grease and limit the entry of larger contaminants while keeping running friction comparatively low. Unlike contact seals, they do not provide the same degree of protection against fine dust, splashing water or moisture. SKF lists a 5,300rpm limiting speed and an 11,000rpm reference speed; these are different catalogue values, and actual permissible running speed depends on lubrication, loading, temperature and operating conditions. The bearing has normal (CN) radial internal clearance, a sheet steel cage and an approximate mass of 0.94kg. For replacement work, verify both the shield type and internal clearance, as the 6017-2Z, 6017-2RS1 and C3 variants should not be assumed interchangeable in every application.
