Excavator hydraulic cylinder cup liner

Hydraulic cylinder cup for excavators (taking oil-free lubricated bearings as an example) Product parameters: Base material: Using steel plates as the substrate to provide stable structural support. Intermediate layer material: Sintered spherical bronze powder enhances wear resistance and load-bearing capacity. Surface Treatment The surface may be covered with a mixture of polytetrafluoroethylene (PTFE) and lead, or other low friction materials to reduce friction and wear. Lubrication characteristics: Oil free or low oil lubrication design, suitable for environments where refueling is impossible or difficult, reducing maintenance requirements. Friction and wear performance: Low friction coefficient reduces energy loss and heat generation. Good wear resistance and extended service life. Carrying capacity: Having appropriate elasticity and plasticity, it can distribute stress over a wider contact surface and improve load-bearing capacity. Work accuracy: The static friction coefficient i…
