Self-Aligning Ball B. SKF 2201 ETN9

The SKF 2201 ETN9 self-aligning ball bearing, with a 12 mm bore, automatically compensates for misalignment caused by shaft deflection during operation.

This double-row roller bearing, made from standard bearing steel (100Cr6), features two rows of balls on a common hollow-spherical outer ring raceway. Thanks to this design, the bearing is insensitive to misalignment or dynamic shaft deflection between the shaft and housing. With main dimensions of 12 mm inner diameter and 32 mm outer diameter, and a width of 14 mm, this model is suitable for compact bearing arrangements subjected primarily to radial loads.

In which applications is the 2201 ETN9 self-aligning ball bearing used?

The bearing is primarily used where shaft deflection or misalignment between two bearing positions may occur, without causing additional friction or edge pressure. Typical applications include compact shaft guides and designs with separate housings in general mechanical engineering. As an open design without an integrated seal, the bearing runs smoothly and can be flexibly lubricated with grease or oil via the housing design.

What characteristics distinguish the polyamide cage during operation?

Thanks to its low mass, the polyamide cage reduces inertial forces during rapid acceleration and promotes smooth running. Furthermore, the polyamide material contributes to vibration damping during operation. In combination with the standard radial bearing clearance and the standard tolerance class P0/PN or ABEC 1, the bearing covers a wide temperature range from -30 to +120 degrees. As the bearing is of an open design, the installation environment must be clean.
