Deep Groove Ball Bearings SKF 4302 ATN9

The SKF 4302 ATN9 double-row deep groove ball bearing, measuring 15x42x17 mm, offers a compact design for combined loads whilst ensuring smooth running.

The SKF 4302 ATN9 double-row deep groove ball bearing accommodates radial forces as well as axial loads in both directions. Thanks to its two rows of balls, this design can handle higher loads than single-row bearings of a comparable size. Manufactured from rolling-element bearing steel (100Cr6), this version is suitable for demanding applications in machinery and fixture construction. With a bore of 15 mm, an outside diameter of 42 mm and a width of 17 mm, the roller bearing fits into compact installation spaces.

What is the 4302 ATN9 double-row deep groove ball bearing suitable for?

Design engineers and maintenance technicians use this double-row design primarily where installation space for larger shaft diameters is limited, yet higher load-carrying capacities are required. Typical applications include compact shaft mountings with combined load directions. As this is an open bearing without integrated sealing washers, it operates with low friction. It is preferably used in sealed housings with an external lubrication supply.

What are the distinctive features of the polyamide cage in the 4302 ATN9 bearing?

The designation ATN9 indicates a polyamide cage that guides the rolling elements and reduces friction and noise during operation. The permissible temperature range is from –20 to +120 degrees Celsius. Thanks to the standard radial bearing clearance and tolerance class P0 (ABEC 1), the component is straightforward to install. As no seals are integrated, the bearing location must be protected against dirt particles to prevent premature wear on the raceways.
