Self-Aligning Ball B. SKF 1206 ETN9

The SKF 1206 ETN9 double-row self-aligning ball bearing, measuring 30 × 62 × 16 mm, compensates for misalignment and supports shafts with low friction.

The SKF 1206 ETN9 self-aligning ball bearing is a double-row rolling bearing made from standard 100Cr6 bearing steel with a cylindrical bore. Thanks to the shared spherical raceway in the outer ring, the two rows of balls automatically adjust to shaft deflection or misalignment. With a bore of 30 mm, an outer diameter of 62 mm and a width of 16 mm, this design complies with the standard tolerance class P0/PN (ABEC 1). The component primarily accommodates radial forces as well as low axial loads in both directions.

What is the 1206 ETN9 self-aligning ball bearing suitable for?

Designs featuring long shafts or split housings are prone to elastic deflection and misalignment during operation. This rolling bearing compensates for such angular misalignments directly within the bearing itself, without edge pressure or increased friction impairing its function. Typical applications can be found in mechanical engineering and in shaft mountings where there is a risk of deflection. The design is specifically intended for applications where the shaft is misaligned with the bearing housing.

What are the key features of the ETN9 polyamide cage?

The suffix ETN9 denotes a polyamide cage that guides the balls and keeps lubricant requirements to a minimum. Compared with solid metal cages, the plastic cage offers the advantages of low weight, minimal inertia and smooth running characteristics. This open bearing has a specified permissible temperature range of –30 to +120 degrees. As the design is open, the lubricant is selected to suit the operating conditions and the bearing location is protected by the housing.
