Deep Groove Ball Bearings SKF 4213 ATN9

The SKF 4213 ATN9 deep groove ball bearing, with its two rows of balls, offers compact load-carrying capacity with a 65 mm bore, 120 mm outer diameter and 31 mm width.

The 4213 ATN9 deep groove ball bearing is a double-row radial ball bearing made from standard 100Cr6 rolling-element steel. Thanks to its double raceways, this design can withstand higher radial loads than single-row variants of comparable dimensions. The integrated polyamide cage guides the rolling elements evenly and ensures smooth running. The bearing is designed as an open type and is suitable for applications with an external lubrication supply.

What is the 4213 ATN9 double-row deep groove ball bearing suitable for?

Double-row roller bearings of this type are primarily used when the available radial installation space is too limited for roller bearings, yet the load exceeds the load-carrying capacity of a standard deep-groove ball bearing. Typical applications can be found in general mechanical engineering and on supported shafts in gearbox designs. As both rows of balls provide parallel guidance, the bearing unit accommodates not only radial forces but also moderate axial forces in both directions.

What are the operating characteristics of the ATN9 polyamide cage?

The suffix ATN9 denotes the bearing design with a polyamide cage. This cage material is characterised by its low weight and good damping properties, which reduce noise levels during operation. The permissible temperature range is from –20 to +120 degrees Celsius. As the bearing is of an open design, the installation point requires effective environmental sealing against dirt and moisture.
