A one-stop self-lubricating bearing supporting service provider spanning the entire industrial chain
Relying on the mature material system and precision manufacturing technology of the full range of oil-free self-lubricating bearings, the products deeply penetrate the industrial intelligent manufacturing scenes of various industries, achieving full coverage of all working conditions in all fields.
The universal tensile testing machine tests the tensile strength of the substrate, the peeling strength of the coating, and the bonding strength of the lining to prevent bearing pressure delamination and delamination cracking.
The friction and wear testing machine simulates actual working conditions, tests the friction coefficient and wear resistance, verifies the self-lubricating performance, and is the core performance testing equipment for oil-free bearings.
The hardness tester detects the hardness of the steel plate substrate and sintered copper powder. If the hardness is too high, it is prone to brittle cracking, and if it is too soft, it is prone to deformation. It controls the raw materials and sintering process.
