The SKF 6216-2Z double shielded deep groove ball bearing provides robust shaft support for industrial machinery operating with substantial radial loads and moderate axial forces in either direction. Its 80mm bore, 140mm outside diameter and 26mm width make it suitable for equipment designed around the 6216 series mounting envelope. The deep groove raceway geometry combines straightforward installation with low-friction rolling performance, while the sheet steel cage maintains ball spacing during operation. SKF catalogue specifications give a basic dynamic load rating of 72.8kN and a basic static load rating of 55kN, providing useful reference values for load assessment and bearing life calculations. The normal (CN) radial internal clearance should be distinguished from the increased clearance of the 6216-2Z/C3 variant.
The 2Z suffix identifies a metal shield on each side, rather than the contacting rubber seals used on the 6216-2RS1. These non-contact shields help retain the factory-applied grease and reduce the entry of larger particles without creating the same level of seal friction. They are therefore a practical choice for relatively clean, enclosed machinery where efficient rotation matters more than protection against fine dust or water ingress. SKF lists a reference speed of 9,500rpm and a limiting speed of 4,800rpm; the limiting speed must be respected when assessing the complete operating arrangement. The bearing is not designed for routine relubrication, so correct selection, alignment and mounting are important to achieving its intended service life.
Typical Applications:
Industrial electric motors and rotating drive shafts
Ventilation fans and air-handling machinery
Centrifugal pumps in protected installations
Enclosed conveyor and transmission equipment
Industrial gearboxes and power transmission assemblies
