Deep Groove Ball Bearings FAG 6320 -C3

The FAG 6320-C3 deep-groove ball bearing is an open, single-row rolling bearing with a 100 mm bore, an outer diameter of 215 mm and increased bearing clearance.

As a single-row radial ball bearing, the FAG 6320-C3 deep groove ball bearing accommodates both radial forces and axial loads in both directions. With key dimensions of 100 mm inner diameter and 215 mm outer diameter, and a width of 47 mm, the component can withstand high loads in continuous industrial operation. It is manufactured from 100Cr6 rolling-bearing steel, which gives the raceways and balls a high degree of dimensional stability. As the bearing is of an open design, it can be flexibly integrated into existing lubrication systems.

In which applications is the 6320-C3 deep groove ball bearing used?

Design engineers primarily select this size for heavy-duty shaft mountings in general mechanical and plant engineering, where shafts with a diameter of 100 mm are supported. Due to its open design without integrated sealing washers, the bearing is designed for enclosed housings with oil circulation lubrication or for installation spaces with separate external housing seals. The permissible temperature range is from –30 to +150 degrees Celsius.

What does the C3 clearance rating mean for the 6320 deep-groove ball bearing?

The abbreviation C3 indicates a slightly increased radial bearing clearance compared with the standard version. This additional clearance between the inner ring, outer ring and the rolling elements compensates for thermal expansion when temperature differences arise between the shaft and the housing during operation. Tight fits also reduce the bearing clearance during press-fitting. A sturdy sheet steel cage guides the rolling elements with standard tolerance P0 or ABEC 1. When designing the assembly, you should provide for a suitable external lubrication supply and sealing.
