Deep Groove Ball Bearings SKF 6316 -2Z/C3

SKF single-row deep-groove ball bearing 6316 -2Z/C3 with an 80 mm bore, non-contacting sheet metal shields and increased C3 radial clearance for industrial rotary applications.

The SKF 6316 -2Z/C3 single-row deep groove ball bearing is designed primarily to accommodate radial loads as well as moderate axial loads in both directions. Manufactured from standard 100Cr6 rolling-element bearing steel, this unit has dimensions of 80 x 170 x 39 mm. The two metal cover plates protect the interior from coarse particles without generating additional friction. This makes the component suitable for speeds within a temperature range of -20 to +120 degrees. You will receive a ready-to-use bearing with standard tolerance P0.

What is the 6316-2Z/C3 deep-groove ball bearing suitable for?

This deep-groove ball bearing is used in industrial drive and shaft mountings where combined radial and axial loads, as well as a non-contact seal, are required. Thanks to the C3 clearance, the bearing compensates for thermal expansion that occurs between the shaft and housing during continuous operation. The sheet steel cage guides the rolling elements in an orderly manner along the raceway. The design, which has no flange or ring groove on the outer ring, allows for straightforward installation in cylindrical housing bores.

What does the combination of 2Z end shields and C3 bearing clearance mean?

The designation 2Z stands for sheet steel cover plates fitted on both sides. These gap seals keep out coarse dirt but, unlike abiding sealing lips, do not cause any additional frictional torque. The suffix C3 indicates a slightly increased radial bearing clearance compared with the standard version. This variant is intended for applications where tight fits on the 80 mm shaft or a temperature gradient between the inner and outer rings reduce the operating clearance whilst the bearing is in operation. The component is designed for operation in the temperature range from -20 to +120 degrees.
