mini excavator undercarriage

The function of the oil filter is to caterpillar filters out the sundries, gums and moisture in the oil, and deliver clean oil to each lubricating part. In order to reduce the frictional resistance between the relatively moving parts in the engine and reduce the wear of the parts, the oil is continuously transported to the friction surface of each moving part to form a lubricating oil film for lubrication. The engine oil itself contains a certain amount of gum, impurities, moisture and additives. At the same time, during the working process of the engine, the introduction of metal wear debris, the entry of debris in the air, and the generation of oil oxides make the debris in the oil gradually increase. If the oil directly enters the lubricating oil circuit without being filtered, the sundries contained in the oil will be brought into the friction surface of the moving pair, which will accelerate the wear of parts and reduce the service life of the engine.

Hitachi excavator filters product requirements 1. Strength requirements, production integrity requirements, withstand pressure difference, bear installation external force, bear pressure difference alternating load 2.

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!

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.

The idler pc200, which is also called idler group, idler assy, front idler or idler wheel, is one part of undercarriage parts for crawler heavy equipments such as excavator, bulldozer, crane, drilling machine etc. The idler pc200 is made of idler shell, shaft, brackets, Bi-metallic Bearings and seal group. It is made by casting or forging, machining, heat treatment, assembly, painting etc. The quality and working life depends on the quality of raw steels, the hardness of rail surface, the depth of hardness layer, the quality of seal group etc. The misalignment of the idler excavator has a serious impact on other parts of the walking mechanism, so we need to adjust the gap between the guide wheel guide plate and the track frame to achieve the purpose of extending the life of the walking mechanism. When adjusting the gap, pay attention to use the gasket between the guide plate and the bearing to correct it. If the gap is large, remove the gasket; if the gap is small, add a gasket.
