Deep Groove Ball Bearings SKF 4200 ATN9

The SKF 4200 ATN9 double-row deep-groove ball bearing, measuring 10x30x14 mm, offers a compact design for combined radial and axial loads.

Thanks to its two adjacent rows of balls, this 4200 ATN9 double-row deep groove ball bearing can withstand higher radial forces than single-row variants with the same outer diameter. SKF manufactures the rings and rolling elements from standard 100Cr6 bearing steel to tolerance class P0/PN (ABEC 1). Designed as an open bearing, this component is suitable for designs with external sealing and lubrication via an existing oil bath or centralised lubrication system.

What is the 4200 ATN9 deep groove ball bearing suitable for?

Design engineers use the 4200 ATN9 deep-groove ball bearing when limited radial installation space must be combined with a required load-carrying capacity. This design primarily supports radial loads whilst simultaneously accommodating axial forces in both directions. Typical applications include general mechanical engineering, gearboxes and guide rollers. Thanks to its open design, lubricant reaches the raceways unimpeded, allowing heat to be dissipated directly into the lubrication circuit during operation.

What are the operational characteristics of the ATN9 polyamide cage?

The designation ATN9 refers to a polyamide cage that keeps the rolling elements spaced apart. The material reduces mass compared with solid metal cages and minimises friction losses and operating noise. The permissible temperature range is from –20 to +120 degrees Celsius. When designing the bearing, select lubricants that are compatible with the cage material and take the standard radial bearing clearance into account when determining the fits between the shaft and housing.
