Product Knowledge
Oil seals are critical components that prevent fluid leakage and contamination in rotating shafts. The ZR280C oil seal is used in the hydraulic system of Zoomlion’s rotary drilling rigs, while the QSM11 oil seal is essential for sealing the crankshaft in Cummins QSM11 diesel engines. Both are designed to withstand high pressure, temperature, and chemical exposure.
