ENDLESS TRACK

An endless track is provided which is particularly adapted to be supported by a slide rail suspension system and moved in an endless path thereabout. The endless track comprises a main body portion having a ground engaging surface and an inside surface and is provided with a plurality of bearing inserts fixed to the main body portion and such inserts comprise a part of the inside surface. Each of the inserts is arranged in an associated row which extends in an endless path and each insert has an outside bearing surface which is adapted to engage associated rails of the slide rail system for movement of the track about such slide rail system with optimum flexibility and in a substantially frictionless manner. Certain ones of the inserts may have means for guiding the track as it is moved along its slide rail system.
