What are the differences between the friction-welded mini excavator track rollers and the traditional type of track roller? 1.Friction-welding mini excavator track rollers is better in the wear-resistance and has longer working lifetime. 2.Consumption of material For traditional track roller, the roller bodies are connected by the welding rod. For friction-welding mini excavator track rollers, the roller bodies are connected by the friction between roller bodies.Friction part of roller will be added more material to make sure roller is conformed to the standard size after friction-welding. 3.Interior parts For traditional track roller, the welding is done after two processes of fine machining, therefore the requirement to the size of interior parts is not that severe. For friction-welding track roller, after the welding, there is one more fine ma-chinning with concentric locating to make sure the conformity of inner sizes.And for which, the requirement to the size of interior parts is severe.Interior parts for friction-welding track roller are with higher standard. 4.Differences on the manufacturing processes

Hitachi excavator undercarriage parts mainly track rollers, sprockets, idlers, carrier rollers, and tracks. Track roller: As the name implies, it plays a supporting role and is located between the lower surface of the left/right beam of the undercarriage and the crawler, depending on the tonnage of the excavator. Usually there are 5-10 on one side. Driving sprockets: plays the role of driving the crawler, fixed on the traveling motor, and transmits the driving force of the traveling motor to the crawler through the gear structure. Usually 1 on each travel motor. Idler wheel: plays the role of guiding the track and is located at the end opposite to the driving force. Usually there are 2 per excavator.

Track adjuster assemblies are available to suit most makes and models of Excavators and Dozers A track adjuster assembly consists of a recoil spring,cylinder and a yoke, It is made by forging, heat treatment.All adjusters are manufactured to OEM specifications, are fully inspected and tested to ensure correct fitment and performance.

High-efficiency, High-quality Komatsu track adjuster Track adjuster assemblies are available to suit most makes and models of Excavators and Dozers A track adjuster assembly consists of a recoil spring,cylinder and a yoke All adjusters are manufactured to OEM specifications, are fully inspected and tested to ensure correct fitment and performance Maintaining proper track tension is critical for receiving satisfactory track life. Adjusters are designed to absorb shock, provide proper track tension and protect idlers and track systems. Weak or broken recoil springs, or poorly functioning adjusters may shorten track and idler lift.
