How to select a carrier roller for your excavator/bulldozer/loader ?
When you select a carrier, it is important to select according to your excavator's brand and model.
6 tons, 13 tons, 20 tons, and 30 tons cannot be mixed, as the size, shaft diameters, and installation distances of these carrier rollers are different. The groove spacing of the carrier roller must be consistent with the track pitch, otherwise it is very easy for the chain to get stuck, wear out quickly, and fall off easily.
