MingYu Sealing Technology engineers and manufactures high-performance shaft seals, piston rod seals, and rotary lip seals designed for demanding hydraulic, pneumatic, and mechanical drivetrains. Built under rigorous ISO 9001 and IATF 16949 quality frameworks, our precision-molded dynamic sealing elements deliver zero-leakage fluid retention, superior dry-run protection, and high-pressure extrusion resistance across critical rotating and reciprocating equipment.
Heavy-duty hydraulic cylinder rods, industrial press plungers, and pneumatic linear actuators.
Industrial speed reducers, electric motor driveshafts, pumps, and rotary transmission hubs.
Excavator boom cylinders, agricultural steering rods, and vehicle axle drive shafts.
| Material Type | Temp. Range | Dynamic Characteristics & Resistance | Pressure Rating |
