Excavator parts SK25SR Track roller

Kobelco SK25SR track roller is an important part of Kobelco SK25SR mini excavator chassis. Its main role is to support the body weight of the excavator, so that the excavator can walk smoothly under various ground conditions. It can also limit the lateral movement of the track and prevent the track from derailing.

Kobelco SK25SR track roller is usually made of high-quality materials, such as 50Mn, 40Mn2, etc., after forging, machining and heat treatment and other processes, with high strength, wear resistance and good sealing. The hardness of the wheel body surface after quenching is higher to increase the wear resistance, and can adapt to the complex working environment and heavy work load of the excavator.
