Deep Groove Ball Bearings SKF 6316 -2Z

The SKF 6316-2Z deep groove ball bearing, measuring 80 × 170 × 39 mm, accommodates both radial and axial loads at high speeds.

The 6316-2Z deep groove ball bearing is a single-row radial ball bearing made from standard rolling-element steel (100Cr6) in SKF’s Explorer performance class. With a bore of 80 mm, an outside diameter of 170 mm and a width of 39 mm, this rolling bearing is suitable for industrial applications involving combined loads. Fitted with a sheet steel cage and standard radial clearance, the unit can handle typical radial forces and moderate axial forces in both directions. It is manufactured to tolerance class P0/PN (ABEC 1).

What is the 6316-2Z deep groove ball bearing suitable for in industrial drives?

This rolling bearing is used in rotating assemblies and drive shafts where the shaft diameter is 80 mm. Thanks to the non-contacting cover plates, the design is suitable for medium to high speeds, as no additional frictional heat is generated at the cover plates compared to sliding seals.

The permissible operating temperature range is from -20 to +120 degrees. The design is intended to absorb radial forces and, thanks to the symmetrical internal structure, to support forces acting on both sides.

What is the function of the cover plates on both sides?

The cover plates on both sides of the 6316-2Z deep groove ball bearing protect the bearing interior from coarse particles and retain the grease in the rolling element chamber without causing friction losses. For dry operating conditions with normal thermal loads, this cover provides a low-maintenance solution without any speed limitation due to sliding friction.

Before installation, check the fits on the flangeless cylindrical outer ring and on the shaft. The standard radial bearing clearance requires dimensionally accurate bearing seats to prevent the rolling elements from becoming jammed after press-fitting.
