The function of the roller is to transfer the weight of the locomotive group to the ground and roll it on the track. To prevent derailment, the roller should also be able to prevent the track from moving laterally relative to it. Rollers often work in mud and sand, and withstand strong impacts, the working conditions are extremely harsh, and the rim is easy to wear. The requirements for the roller are: the rim is wear-resistant, the bearing seal is reliable, and the rolling resistance is small.
Our products are according to the standard of OEM to manufacture.
Monolithic or rubber tracks, because they have raised teeth cast on the inner surface of the track shoes to prevent lateral movement of the track to the rollers, have a straight roller rim and do not require a flange. But each roller must be a double-row rim. The number of rollers can make the grounding pressure of the track more uniform, so that walking on the wet and soft soil can reduce the subsidence, but on the other hand, because the length of the track is certain, the number of rollers is more, the diameter of each of them must be small, which increases the rolling resistance, generally speaking, as the crawler walking mechanism of the combine harvester, the number of rollers is often 3~4, and a few use 6. Rollers are commonly used for plain bearings (such as iron-based powder metallurgy oil-impregnated bearings), but rolling bearings are also used. Regardless of the type of bearing, it is necessary to prevent muddy water from ingress. The rim of the roller should be wear-resistant, generally made of 45 steel, and the hardness of the rim surface after quenching is not less than HRC53.
