    Excavator Undercarriage Parts SK350 Track Roller For KOBELCO

    Excavator track rollers are one of the important accessories of excavators. They are used to support the weight of the excavator, while rolling on the track (rail link) or the track plate of the track. Slip off. Crawler track rollers can be divided into unilateral track rollers and bilateral track rollers according to their structure, using sliding bearings and rolling shafts. The supporting rims are quenched and their hardness reaches 355-440 HB.

    Excavator Undercarriage Parts PC400 Sprocket For KOMATSU

    A sprocket is a type of wheel with cog-type buckle sprocket, which is used to mesh with a block with a precise pitch on a chain link or cable. PC400 sprocket is mainly used in Komatsu excavators and bulldozers

  • Excavator Undercarriage Parts EX300 Sprocket For HITAHCI

    Excavator Undercarriage Parts EX300 Sprocket For HITAHCI

    The compact structure of EX300 sprocket can realize large transmission ratio, high efficiency and long service life. Chain drive has the characteristics of high sprocket teeth and chains participating in meshing at the same time, large sprocket cogging arc and small gear stress concentration. Therefore, the EX300 chain drive has a large load carrying capacity and the sprocket surface wear is relatively light.

    EX400 sprocket drive has extremely high speed and low noise. In chain transmission, the processing accuracy and installation accuracy of chain and stainless steel sprocket and the accuracy of center distance are lower than the requirements of gears. It is easier to change the parameters (transmission ratio, center distance, etc.) of the existing chain transmission to achieve simple installation and maintenance.

    The sprocket is divided into a driving sprocket and a driven sprocket. The driving sprocket is mounted on the engine output shaft through a spline; the driven sprocket is mounted on the motorcycle driving wheel and transmits power to the driving wheel through the chain. Generally The driving sprocket is smaller than the driven sprocket, which can reduce the speed and increase the torque.

    Excavator Undercarriage Parts E330 Sprocket For CAT

    After the standard heat treatment of the drive wheel blank of our sprocket, the hardness of the substrate reaches above HB235, and the drive teeth are subjected to medium frequency induction hardening and low temperature tempering. The surface hardness can reach HRC48-54, and the hardening depth is higher than 5-10mm (HRC45). It not only provides accurate power under harsh working conditions, but also has excellent wear resistance and has the effect of extending product life and reducing customer costs.
