Deep Groove Ball Bearings SKF 4214 ATN9

The SKF 4214 ATN9 deep groove ball bearing, with two rows of balls and dimensions of 70x125x31 mm, offers increased radial load-carrying capacity for demanding shaft mountings.

The 4214 ATN9 deep groove ball bearing is an open, double-row rolling bearing made from standard bearing steel (100Cr6). The double-row design can withstand higher loads than single-row variants whilst occupying the same installation space. With a bore of 70 mm, an outside diameter of 125 mm and a width of 31 mm, this bearing is suitable for compact installation spaces. The open design allows for flexible use with on-site oil or grease lubrication.

What is the 4214 ATN9 double-row deep-groove ball bearing suitable for?

This rolling bearing is recommended for shaft mountings where single-row designs reach their load limits. Typical applications include drives and mechanical components subject to high forces. Thanks to the raceway geometry, the bearing can accommodate not only high radial forces but also axial forces in both directions. The open design without seal washers is ideal for applications operating within enclosed housings and supplied directly via the system’s lubrication circuit.

What are the advantages of the polyamide cage in this design?

The material polyamide (ATN9) is characterised by its low weight and good damping properties. As a result, the bearing runs smoothly and generates less friction than designs with solid metal cages. The permissible operating temperature range is from –20 to +120 degrees Celsius. Before installation, it should be noted that the bearing is designed with standard radial clearance and tolerance class P0/PN or ABEC 1, and requires an external housing seal.
