Deep Groove Ball Bearings SKF 61848 MA

With dimensions of 240 x 300 x 28 mm, the 61848 MA deep-groove ball bearing offers a very narrow design for compact large-shaft constructions in mechanical engineering.

The 61848 MA deep groove ball bearing is a single-row radial ball bearing in an open design, manufactured from standard rolling-element bearing steel (100Cr6). As a rolling bearing in the very light size series, it combines a large shaft diameter of 240 mm with an outer diameter of 300 mm and a width of 28 mm. The bearing is manufactured by SKF and features a solid, externally guided brass cage that absorbs mechanical loads under demanding operating conditions.

In which designs is the 61848 MA deep groove ball bearing used?

Design engineers choose this type for large assemblies where there is limited radial installation space. Thanks to its favourable cross-sectional ratio, the component is particularly suitable for guiding hollow shafts, rotary joints and spindles that primarily have to absorb radial forces and moderate axial forces. As it is an open bearing without integrated sealing washers, it can be integrated directly into existing oil circulation or centralised lubrication systems.

What are the advantages of the MA external-guided brass cage?

The suffix ‘MA’ denotes a solid brass cage guided on the outer ring. This external guidance effectively stabilises the rolling element guidance even at varying speeds and under high centrifugal forces. The brass material dampens vibrations and is resistant to lubricant additives. At operating temperatures ranging from –20 to +150 degrees, the bearing retains its geometric dimensional stability within tolerance class P0/PN.
