One common application of machine rollers is known from the field of machine tracks. Machine tracks in tracked machines, such as excavators, tracked tractors or other tracked machines, are typically used to support the weight of the machine on the track as it advances in an endless loop around a plurality of rotatable track engaging elements. Depending on the design of the track, a plurality of so-called track rollers may be mounted below or otherwise to the track roller frame and roll on the inside surfaces of the track links or shoes as the track moves around one or more idler wheels and drive sprockets.
