Hitachi excavator filters product requirements 1. Strength requirements, production integrity requirements, withstand pressure difference, bear installation external force, bear pressure difference alternating load 2. Requirements for smoothness of oil passage and flow resistance characteristics 3. Resistant to a certain high temperature, compatible with the working medium 4. The fibers of the filter layer cannot be displaced and fallen off 5, to carry more dirt 6. Normal use in high altitude and cold areas 7. Fatigue resistance, fatigue strength under alternating flow 8. The cleanliness of the filter element itself must meet the standard We are top supplier of Donaldson filters in China, you can get lowest price of original Donaldson filters from us!

Kyushan is established in 2004 , we produce OEM mini excavator swing bearing replacement, slew drive, pinion, FH has passed ISO9001-2005, SGS, CAPE etc, FH also accept the service durability test, resist fatigue test, anti-corrosion test and anti-terrible temperature test, which is widely used for Construction machinery, port, AI and new energy industries.

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.
