Excavator parts SH60(SF) Track roller

The Sumitomo SH60 (SF) track roller is an important part of the Sumitomo SH60 (SF) excavator chassis. It mainly assumes the role of supporting the weight of the excavator’s body, rolling on the guide rails of the tracks or the surface of the track plate, reducing the friction between the tracks and the chassis, and restricting the lateral slippage of the tracks, to ensure that the excavator can travel stably in the direction of the tracks. It is generally made of high-strength materials with good wear resistance and load-bearing capacity to adapt to the complex construction conditions of the excavator. The structure usually consists of wheel body, supporting wheel axle, axle sleeve, sealing ring, end cover and other components.
