>> Product Use

  1. Reduce wear: During the operation of the loader, there will be frequent friction and collision between the various parts. The liner can serve as a buffer layer to reduce these direct contacts, thereby reducing the degree of wear of the parts and extending the service life of the equipment. For example, the liner between the bucket and the connecting parts can effectively prevent the bucket from excessively wearing the connecting parts when loading and unloading materials.

  2. Sealing and dust prevention: The liner can play a sealing role to prevent dust, soil and other impurities from entering the key parts of the equipment, such as the hydraulic system, bearings, etc. Taking the liner of the hydraulic cylinder as an example, a good seal can prevent the leakage of hydraulic oil and prevent dust from entering the cylinder and affecting its normal operation.

  3. Shock reduction and noise reduction: The loader will generate large vibrations and noise when working. The liner has a certain elasticity, which can absorb part of the vibration energy and reduce the vibration amplitude of the whole equipment. At the same time, it can also reduce the noise caused by the collision and friction of the parts and improve the working environment of the operator.

  4. Adjust the gap: During the assembly process of the equipment, the liner can be used to adjust the gap between the parts to ensure the matching accuracy between the parts. For example, in the gearbox, the liner can adjust the gap between the gears to ensure the normal meshing and transmission efficiency of the gears.
