Deep Groove Ball Bearings SKF 6330 M

The SKF 6330 M deep groove ball bearing, with a 150 mm bore, brass cage and open design, provides a solid foundation for demanding industrial applications.

This single-row deep-groove ball bearing 6330 M, made from standard rolling-element bearing steel 100Cr6, is primarily designed to withstand radial loads; however, due to its design, it can also accommodate moderate axial forces in both directions. As the bearing is of open design, it has no integrated sealing washers. A guided brass cage maintains the rolling elements at a precise distance from one another. With dimensions of 150 × 320 × 65 mm, the component complies with tolerance class P0/PN or ABEC 1 and features a standard radial clearance for standardised mounting conditions.

What is the 6330 M deep groove ball bearing suitable for in industrial bearing applications?

Design engineers prefer to use the 6330 M deep groove ball bearing in bearing arrangements where high radial forces and additional axial loads are present. With a permissible temperature range of –20 to +150 degrees, the component is suitable for environments subject to continuous thermal stress. As the outer ring is designed without a flange or circumferential groove, the bearing can be fitted directly into cylindrically machined housing bores.

What are the characteristics of the brass cage in the M variant?

The suffix ‘M’ denotes the version with a brass cage, which is characterised by high strength and good emergency running properties. The cage reliably withstands loads caused by vibrations and accelerations. As the design is open and is not factory-greased, the bearing housing requires external sealing as well as lubrication as required, using grease or lubricating oil.
