Deep Groove Ball Bearings FAG 6240 -M

The FAG 6240-m deep-groove ball bearing is an open, single-row heavy-duty bearing with a brass cage, an outer diameter of 360 mm and a width of 58 mm, designed for demanding industrial drives.

The single-row deep-groove ball bearing 6240-m combines radial load-carrying capacity with the ability to accommodate axial forces in both directions. FAG manufactures this rolling bearing from standard bearing steel and fits it with a cylindrical bore. Designed as an open bearing, its construction allows for targeted lubrication from the outside. The robust brass cage guides the rolling elements precisely, enabling the assembly to operate at temperatures ranging from –30 to +200 °C.

What is the 6240-m deep-groove ball bearing suitable for in practice?

Design engineers and maintenance technicians primarily use this deep-groove ball bearing in heavy machinery, gearboxes and large industrial drives. The bearing fulfils its function wherever high radial loads occur and moderate axial forces need to be supported. Thanks to the brass cage, this version can also withstand strong vibrations and increased thermal stresses. The open design also allows operation in oil-lubricated recirculating systems and separate lubrication chambers without disruptive seal friction.

What advantages does the brass cage offer in this large bearing?

Brass is a material with good emergency running properties and reliably absorbs mechanical shock loads. Together with the standard radial bearing clearance, the combination of roller bearing steel and a brass cage contributes to smooth, trouble-free rotation. As no integrated sealing washers are fitted, a suitable external seal must be provided in the housing. This ensures that the lubricant remains within the bearing area and that ambient dust is kept out.
