Deep Groove Ball Bearings SKF 6315 -2Z

The SKF 6315-2Z deep groove ball bearing, with dimensions of 75 × 160 × 37 mm, offers protection on both sides against foreign particles under combined radial and axial loads.

The 6315-2Z deep groove ball bearing is a single-row radial ball bearing made from standard rolling-element steel (100Cr6) in the SKF Explorer design. The design primarily accommodates radial loads and supports axial forces in both directions. A sheet steel cage guides the rolling elements at a uniform spacing within the deep raceways. With standard radial clearance and tolerance class P0/PN, this unit is suitable for standardised fits in mechanical and plant engineering.

What operating conditions does the 6315-2Z deep-groove ball bearing cover?

This rolling bearing is used in industrial applications that require the guidance of rotating shafts under medium to high loads. Thanks to the cylindrical outer ring without a flange or groove, the component fits flush into cylindrical housing bores. The Explorer design is aimed at achieving high material purity and precisely matched contact surfaces. With operating temperatures ranging from –20 to +120 degrees, the bearing covers the typical thermal range of industrial applications.

What is the function of the cover plates in the -2Z version?

The suffix -2Z denotes two non-contacting cover plates made of sheet steel, which are fixed to both sides of the outer ring. They form a narrow sealing gap with the inner ring and keep dust and solid particles out of the bearing interior. As the sheet metal discs do not come into contact with the rotating parts, no additional frictional torque is generated. This allows for speeds on a par with open bearing designs.
