Radial Insert Ball B. SKF 1726205 -2RS1

The SKF 1726205 -2RS1 tension bearing, measuring 25x52x15 mm and featuring a ground seal on both sides, offers a compact solution for housings with a spherical seat.

This SKF 1726205 -2RS1 clamping bearing is based on the geometry of conventional deep-groove ball bearings and is made from 100Cr6 rolling-element bearing steel. Unlike many other bearing units, this design has no widened inner ring and no additional fasteners such as grub screws or eccentric rings. It is secured directly via a suitable shaft fit. The roller bearing primarily absorbs radial forces and operates within a temperature range of -20 to +120 degrees Celsius.

What is the 1726205 -2RS1 clamping bearing suitable for?

Design engineers primarily use this bearing where there is limited axial space available on the shaft. Thanks to the spherical shape of the outer ring, the unit compensates for static misalignment when fitted in a suitable housing with a spherical bore. In this way, the system compensates for shaft misalignment caused during assembly or by frame distortion. Typical applications can be found in general mechanical engineering as well as in bearing arrangements with spherical housing mounts.

What are the advantages of the spherical outer ring with a 2RS1 seal?

The spherically ground outer ring allows for angular misalignment within the bearing housing without the risk of edge pressure or premature wear on the raceways. The 2RS1 seal, which seals on both sides, effectively protects the interior against the ingress of dirt particles and splash water. At the same time, the lubricant remains within the bearing chamber. Manufacture to tolerance class P0 (ABEC 1) ensures dimensional accuracy in accordance with standards for standardised fits.
