Self-Aligning Ball B. SKF 2202 ETN9

The SKF 2202 ETN9 double-row self-aligning ball bearing compensates for misalignment and has an inner diameter of 15 mm, an outer diameter of 35 mm and a bearing width of 14 mm.

The SKF 2202 ETN9 self-aligning ball bearing is a double-row rolling bearing with a common hollow-spherical raceway in the outer ring. This design allows the inner ring to tilt relative to the outer ring, enabling the bearing to automatically compensate for angular misalignment and shaft deflection during operation. Manufactured from standard roller bearing steel (100Cr6) to standard tolerance P0/PN or ABEC 1, the version with a cylindrical bore is suitable for a wide range of machine designs in industrial applications.

Where is the 2202 ETN9 self-aligning ball bearing used in cases of misalignment?

This self-aligning ball bearing is primarily selected for bearing arrangements where there are housing misalignments or where shafts deflect elastically under load. Relevant areas of application can be found in general mechanical engineering in systems with larger bearing spacings. As the bearing is of an open design, external seals in the housing provide protection against dirt, whilst grease or lubricating oil reaches the rolling elements directly.

What advantages does the polyamide cage offer in the 2202 ETN9?

The suffix ETN9 denotes a lightweight polyamide cage that precisely guides the rows of balls and promotes smooth running. Together with the standard radial bearing clearance, this roller bearing covers a temperature range from -30 to +120 degrees. In terms of design, the material is characterised by its low weight. Prior to installation, the mounting dimensions of 15x35x14 mm and the housing seal must be checked for compatibility.
