Abstract

In order to create a track roller for crawler chains, consisting of a track oller body, an axle traversing the same as well as bearings and seals arranged between the track roller body and the axle, whereby the axle is affixed to a mount with its ends axially protruding from the track roller body, which has a long life when used as intended, the invention proposes that the bearings (3) radially arranged between the track roller body (1) and the axle (2) be designed as pivoting bearings, so that the load-caused bending of the track roller body or the axle can follow without jamming.
