Self-Aligning Ball B. SKF 2302 E-2RS1TN9

The SKF 2302 E-2RS1TN9 self-aligning ball bearing compensates for misalignment whilst sealed during operation, with an installation dimension of 15 × 42 × 17 mm.

The 2302 E-2RS1TN9 self-aligning ball bearing is a double-row rolling bearing made from standard 100Cr6 bearing steel with a hollow-spherical outer ring raceway. This design automatically compensates for misalignment and shaft deflection during operation. The SKF bearing has a cylindrical bore of 15 mm, an outer diameter of 42 mm and a width of 17 mm. Thanks to its factory-fitted seal, this component is suitable for applications where contamination must be prevented.

In which applications does the 2302 E-2RS1TN9 self-aligning ball bearing compensate for misalignment?

Its main area of application is in bearing arrangements where angular misalignment between the housing and the shaft needs to be compensated for. Typical conditions include longer shaft spans with elastic deflection under load. As the rolling elements pivot on the spherical outer raceway, the bearing continues to rotate smoothly even with slight misalignments. The double-sided contact seal protects the raceways from ingress of particles and moisture.

What is the function of the 2RS1 seal and the polyamide cage?

The suffixes refer to two key features of the design: the designation 2RS1 indicates sealing lips on both sides that retain the lubricant inside the bearing and make it difficult for contaminants to penetrate. The designation TN9 stands for a ball-guided polyamide cage. This plastic cage is characterised by its low weight, elastic properties and smooth running. Together with the standard radial bearing clearance and tolerance class P0/ABEC 1, the component fits precisely into standard assemblies.
