Deep Groove Ball Bearings FAG 6319 -2Z

The 6319-2Z deep groove ball bearing from FAG Rolling Bearings, measuring 95 x 200 x 45 mm, features sheet metal shields on both sides to provide mechanical protection whilst minimising friction.

The 6319-2Z deep groove ball bearing is a single-row rolling bearing made from standard rolling bearing steel (100Cr6), designed primarily for radial loads as well as moderate axial forces in both directions. With a bore of 95 mm, an outer diameter of 200 mm and a width of 45 mm, this bearing is one of the larger components used in mechanical and plant engineering. This component from FAG Wälzlager, supplied ready for installation with cover plates, is designed for direct fitting in demanding industrial applications.

What is the 6319-2Z deep groove ball bearing suitable for in industrial applications?

This bearing is typically used in larger industrial drives, gearboxes and general mechanical engineering, where high radial forces act on the shaft. Thanks to the 2Z cover on both sides, this design is particularly suitable for environments containing dry particulate matter. As the non-contact gap seals do not generate frictional heat, the bearing remains thermally stable even at higher speeds. Installation is therefore recommended wherever low-friction operation is required.

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

The metallic cover plates (2Z) protect the bearing interior from coarse contaminants and retain the grease in the rolling element chamber without causing any additional frictional torque. In combination with the standard radial bearing clearance and the standard tolerance class P0/PN (ABEC 1), this design is intended for conventional installation conditions with standard fit seats. The integrated sheet steel cage guides the rolling elements stably across the entire temperature range from –30 to +120 degrees Celsius.
