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

The track rollers of mini undercarriage parts is to distribute the energy and load of the excavator during work, and to prevent the track and the fuselage from derailing when the excavator is walking. Since most of the track rollers work in sand or harsh working environments, and bear a greater impact force than other components, they are prone to wear, breakage, oil leakage, etc. after a period of work.

Therefore, the track rollers must have a very high bearing capacity, wear resistance and sealing. Kyushan load-bearing wheel adopts high-performance oil seal to ensure that the machine runs smoothly and has a stronger seal. With Kyushan's advanced welding and processing technology, the track rollers has a stronger bearing capacity and is more wear-resistant.

The komatsu excavator undercarriage parts carries the full weight of the excavator and is responsible for the driving function of the excavator. The main damage form is wear, which is concentrated in the following contact parts: the outer surface of the drive wheel teeth and the track pin sleeve: the guide wheel and the track link raceway surface of the track; the roller and the track track link raceway The surface of the carrier roller and the track link of the track; the contact surface of the track pin and the pin sleeve; the track shoe and the ground, etc.

The composition and function of the kobelco undercarriage parts assembly:
1. Support the upper weight of the entire excavator.
2. The power source and actuator for walking and steering.
3. Support the reaction force of the working device when excavating.

The main components of kobelco undercarriage:
1. Lower frame body (welding parts),
2. Guide wheel, driving wheel, carrier wheel, roller, track
3. Bulldozer and oil cylinder.
4. Central rotary joint.
5. Slewing raceway ring (slewing bearing).
6. Travel reducer and motor.

volvo undercarriage parts needs to withstand the harshest working conditions than any other part of the excavator. Not only does the chassis support the overall weight of the machine and propel the entire machine, it also continuously withstands the impact of rocks and other obstacles during operation. volvo undercarriage inspections reduce the risk of unexpected failures and expense - failures that can seriously jeopardize normal operation and potentially affect the entire job site.

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.

Final Drive & Swing Components for excavator:
Planetary volvo excavator sprocket must withstand the high forces of torque generated by the engine and transfer these loads to move the equipment.
All volvo excavator sprocket and final drive gears are manufactured to precise tolerances for reliable operation. The manufacturing method includes a heat treatment process that increases bending strength, prevents case crushing and provides exceptional wear resistancefor a long service life.

The pc200 sprocket wheel, is one part of undercarriage parts for crawler heavy equipments such as excavator, bulldozer, crane, drilling machine etc.
 
The pc200 sprocket wheel is made by casting, machining, heat treatment, painting etc.The pc200 sprocket wheel is made by casting, machining, heat treatment, painting etc.
 
The quality and working life depends on the quality of casting steel, the hardness of rail surface, the depth of hardness layer etc.

The shape of the sprocket pc200 is toothed. When the excavator digs the ground, the stress of the traveling device is relatively large. In addition to the pressure caused by the rotation and twisting of the car body, the toothed sprocket pc200 is in the front, which can play a relatively stable mobility.
