Roller arrangement for working machine undercarriage has axle mounting arrangement positioned in holder so that no point protrudes beyond plane defined by holder

摘要

The arrangement has a body element with a through passage and rolling surface, a first rim or shoulder attached to the body element and inner and outer side wall elements positioned relative to the body element's rotation axis so a linear extension of the outer side wall element intersects the rotation axis at an acute angle to define a holder. An axle mounting is positioned in the holder so no point protrudes beyond a plane defined by the holder. Independent claims are also included for the following: a working machine.
