Deep Groove Ball Bearings SKF 6213 M

The SKF 6213 M deep groove ball bearing, measuring 65x120x23 mm and featuring a brass cage, offers an open rolling bearing solution for demanding industrial drives.

The 6213 M deep groove ball bearing provides users with a single-row radial ball bearing made from case-hardened standard bearing steel (100Cr6) in the SKF Explorer design. This open component primarily absorbs radial forces, but also supports shafts axially in both directions. Thanks to its standard radial clearance and manufacture to tolerance class P0/PN (ABEC 1), the bearing is suitable for standardised fits in conventional mechanical engineering without increased bearing clearance.

Under what operating conditions does the 6213 M deep groove ball bearing perform well?

This design is primarily used where rotating shafts need to be guided at medium to high speeds. As this rolling bearing is of open design, it typically operates in enclosed assemblies with existing oil or grease lubrication. The permissible temperature range extends from –20 to +150 degrees Celsius, ensuring that the bearing assembly retains its dimensional stability even at elevated operating temperatures. This variant does not feature electrical insulation.

What are the distinctive features of the brass cage in the M version?

The suffix ‘M’ denotes the solid brass cage. Brass is a material with high mechanical strength and dampens vibrations during operation. The cage design guides the rolling elements stably within the raceways of the inner and outer rings, particularly under varying loads or high accelerations. The outer ring has no flange or groove, which facilitates installation in through-bores in housings.
