Deep Groove Ball Bearings SKF 6324 M

The SKF 6324 M deep groove ball bearing, with a 120 mm bore and a brass cage, offers high stability for demanding industrial applications.

The 6324 M deep groove ball bearing is a single-row rolling bearing from SKF designed for industrial bearing applications involving high loads. With key dimensions of 120 mm inside diameter, 260 mm outside diameter and 55 mm width, this design accommodates radial loads as well as axial forces in both directions. The rings and rolling elements are made of standard rolling-bearing steel 100Cr6. As an open bearing without an integrated seal, the unit can be connected directly to lubrication systems.

Under what operating conditions is the 6324 M deep groove ball bearing used?

It is primarily used in heavy-duty industrial drives and power units with circulating lubrication. As the bearing is unsealed, lubricating oil or grease circulates unhindered over the raceways, rapidly dissipating any heat generated during operation. This requires a clean, protected housing environment that prevents the ingress of dirt particles. The permissible temperature range of the rolling bearing extends from -20 to +150 degrees Celsius.

What is the function of the brass cage in the 6324 M deep groove ball bearing?

The suffix ‘M’ indicates a solid brass cage. Brass cages guide the rolling elements in a dimensionally stable and low-noise manner, even under shock loads, vibrations or varying speeds. Furthermore, the material offers favourable emergency running properties in the event of short-term lubricant shortages. In combination with the standard radial bearing clearance and the standardised tolerance class P0 (ABEC 1), this design ensures smooth running with standardised shaft and housing fits.
