Deep Groove Ball Bearings SKF 6307 -2Z

The SKF 6307-2Z deep groove ball bearing features sheet metal end shields on both sides and a standard tolerance of P0, with main dimensions of 35 × 80 × 21 mm.

The 6307-2Z deep groove ball bearing is a single-row radial ball bearing made from 100Cr6 rolling bearing steel, with a 35 mm bore, an 80 mm outer diameter and a width of 21 mm. As an SKF Explorer variant, this rolling bearing combines optimised raceway surfaces with high dimensional accuracy. The component primarily accommodates radial forces as well as axial loads in both directions. Thanks to its sheet steel cage and factory-applied grease filling, the bearing is designed for use in industrial applications.

What is the 6307-2Z deep groove ball bearing suitable for in practical operation?

This deep groove ball bearing is typically used on rotating shafts and in general mechanical and plant engineering. With an operating temperature range of -20 to +120 degrees, the bearing operates in standard industrial environments. The non-contacting cover plates on both sides keep foreign particles out without generating any additional frictional torque. This makes this variant suitable for systems operating at medium to high speeds.

What are the advantages of the -2Z cover plates and the standard bearing clearance?

The covers on both sides (-2Z) are made of profiled sheet steel and form a tight sealing gap with the inner ring. They keep the grease inside and protect the raceways from coarse contaminants. The standard radial bearing clearance is designed for a defined operating clearance with standard shaft fits. In conjunction with tolerance class P0 (ABEC 1), the bearing meets common requirements, which facilitates planned replacement during maintenance.
