Deep Groove Ball Bearings FAG 6228

The FAG 6228 deep-groove ball bearing, with a bore of 140 mm and an outside diameter of 250 mm, is designed to withstand high radial loads in industrial applications.

As a single-row deep-groove ball bearing, the 6228 is designed for predominantly radial loads as well as moderate axial forces in both directions. FAG manufactures this open bearing from standard roller bearing steel (100Cr6) with a guided sheet steel cage. With its standardised main dimensions of a 140 mm bore, 250 mm outside diameter and 42 mm width, as well as tolerance class P0/PN, the component can be integrated into machine designs in a standardised manner.

What is the 6228 deep-groove ball bearing suitable for in operation?

Typical areas of application are in industrial mechanical engineering for applications involving high radial forces and continuous shaft guidance. As the bearing is open at both ends, it is suitable for installation in enclosed housings as well as for systems with a central lubrication supply. The wide temperature range of –30 to +200 degrees allows for use in operating environments with increased heat generation.

What are the key considerations for the open design of the 6228 deep groove ball bearing?

As this rolling bearing is designed without integrated sealing discs, the housing design determines the level of protection against dust, dirt particles and moisture. External sealing elements, such as shaft seals or non-contact gap seals, must therefore be provided as part of the design. The bearing is manufactured with standard radial clearance. In the event of significant shaft heating or tight fits, it must be checked whether the radial operating clearance is sufficient to ensure trouble-free operation.
