Excavator undercarriage parts/DAEWOO DH55/DH150/DH220/DH300/DH280/DX260/DX225 Top Roller / Carrier Roller/track roller After forging and heat treatment, in order to ensure the outer body side and the inner body side of the carrier roller to have enduring impact resistance and excellent surface wear resistance.

Short Description:

We specialize in producing high quality excavator and bulldozer carrier roller. Carrier roller is the part installed on the top inside the track.

This top roller is installed beneath the crawler belt to prevent the belt from sagging or rolling over. Their function is to support parallel and rolling of the tracks. Our top roller parts are suitable for mining, earthwork and all environment.

Our HOR series carrier rollers can be used on machinery from Komatsu, Caterpillar, Hitachi, Sumitomo, Kobelco, Kato, and Daewoo.

Undercarriage Parts Top Roller & Carrier Roller

Top Roller Description

Wheel body: forged from 50Mn round steel with good hardenability: The heat treatment process of quenching and tempering and medium frequency surface quenching ensures its strength and wear resistance.

Shaft: 45 # round steel material, heat treatment process of quenching and tempering and medium frequency surface quenching, surface hardness:HRC52-60. depth of hardened layer 3-6mm, excellent comprehensive performance.

Floating oil seal: made of high chromium and high molybdenum alloy.

Hardness HRC65-72 working surface roughness 0.1uM-0.2uM

O-ring: It is produced from butylene and acrylonitrile, which are copolymerized into butylene and acrylonitrile, and has better oil resistance and high temperature resistance.

We manufacture many types and models of carrier rollers and offer customized products that can meet your various needs.

Quality of products

Through quench-tempering processes to ensure excellent mechanical properties, high strength and superior wear resistance to avoid bending and breakage.

Our advanced forging techniques are used to produce the roller body, front cover and rear cover of our HOK series carrier roller.

All of our carrier rollers go through the 2.4MPa water pressure and passes the air tightness testing for excellent sealing.

Shaft uses high-quality manganese steel, quenched and tempered, high-frequency processing to meet the needs of high-intensity operations.

The undercarriage part’s machining and tolerance of fit are designed according to Chinese standards, though we adjust and install the undercarriage parts according to your country’s standards.
