Deep Groove Ball Bearings FAG 6213 -2Z-C3

The FAG 6213 -2Z-C3 deep-groove ball bearing, with dimensions of 65 × 120 × 23 mm and increased bearing clearance, ensures reliable operation under thermal expansion.

The 6213 -2Z-C3 deep groove ball bearing is a single-row rolling bearing with a 65 mm bore, a 120 mm outer diameter and a width of 23 mm. The manufacturer, FAG, produces this bearing from standard roller bearing steel 100Cr6 in tolerance class P0 (normal tolerance). It primarily absorbs radial forces and also supports axial loads in both directions. Thanks to its sheet steel cage and sheet metal covers on both sides, this design is suitable for a wide range of industrial applications in mechanical and plant engineering.

What is the 6213 -2Z-C3 deep groove ball bearing suitable for in operation?

This single-row deep-groove ball bearing is primarily used where rotating shafts with a diameter of 65 mm have to withstand uniform radial loads. Typical applications include industrial drives and rotating machine components with continuous motion. As the component is designed for a temperature range of -30 to +120 degrees, it is suitable for a wide range of industrial environments. The non-contacting cover plates keep solid contaminants out without restricting the rolling ability of the rolling elements.

What are the advantages of the 2Z cover plates and the C3 clearance?

The designation -2Z indicates sheet metal cover plates fitted on both sides. These gap seals protect the bearing interior from solid contaminants and preserve the lubricant chamber without generating additional frictional heat. The suffix C3 denotes a slightly increased radial bearing clearance. This increased radial clearance is beneficial where tight fits on the shaft or housing result in a reduction in bearing clearance, or where temperature differences occur between the inner and outer rings. The cylindrical outer ring has neither a flange nor a ring groove, which facilitates installation in smooth housing bores.
