Self-Aligning Ball B. SKF 1217

The SKF 1217 self-aligning ball bearing (85x150x28 mm) is a double-row, open roller bearing that compensates for both static and dynamic angular misalignment during operation.

The 1217 self-aligning ball bearing is a double-row rolling bearing with a common spherical raceway in the outer ring. This design enables the two rows of balls to compensate for misalignment or shaft deflection during rotation. Manufactured from standard roller bearing steel 100Cr6 and fitted with a sheet steel cage, this bearing is designed for operating temperatures ranging from –30 to +150 degrees. With a cylindrical bore of 85 mm, an outer diameter of 150 mm and a width of 28 mm, it complies with the standard tolerance class P0/PN or ABEC 1.

What are the industrial applications for the 1217 self-aligning ball bearing?

Design engineers and maintenance technicians use the 1217 self-aligning ball bearing in long shaft guides where elastic deflection or misalignment between the bearing locations may occur. The bearing primarily absorbs radial loads and reliably guides the rotating shaft even in the event of slight misalignments. Typical areas of application include industrial applications and mechanical engineering assemblies where housing misalignment or installation-related distortion needs to be compensated for.

What criteria should be taken into account with the open design of the bearing?

The 1217 self-aligning ball bearing is an open design without integrated seals. This allows the lubricant – grease or oil – to be selected to suit the specific operating conditions and, if necessary, replenished from the outside. On-site, an external housing seal is recommended to prevent the ingress of dirt and moisture. The standard radial bearing clearance is designed for standard operating conditions with uniform temperature distribution.
