Excavator hydraulic cylinder cup liner

Oil free lubrication bearings are made of steel plates as the matrix, with spherical bronze powder sintered in the middle, A sliding bearing made by rolling a mixture of polytetrafluoroethylene (PTFE) and lead on the surface. It has the characteristics of low friction coefficient, wear resistance, good corrosion resistance, and no oil lubrication. The use of this product has the advantages of reducing costs, reducing mechanical volume, avoiding shaft biting, and reducing mechanical noise. 1. No oil lubrication or low oil lubrication, suitable for places where refueling is not possible or difficult, and can be used without maintenance. 2. Good wear resistance, low friction coefficient, and long service life 3. Having an appropriate amount of elasticity and plasticity can distribute stress on a wider contact surface, improving the bearing capacity. 4. The static and dynamic friction coefficients are similar, eliminating creep at low speeds, thereby ensuring the working accuracy of the ma…
