60201949 Piston Motor Sany SY1350C1C3KH Tracked hydraulic excavator spare parts

As a core actuator in the hydraulic system of construction machinery, the 60201949 piston motor boasts four major advantages: high efficiency, high torque, precise control, and strong durability. It is widely used in the traveling, slewing, and mixing mechanisms of excavators, tunneling machines, and other construction machinery, as well as in heavy equipment in metallurgy and mining, playing a crucial role in converting hydraulic energy into mechanical energy and outputting powerful power. Utilizing a precision swashplate and piston-driven structure, high-pressure hydraulic oil propels the piston in reciprocating motion, which is then converted into rotary motion by the swashplate. This results in highly efficient energy conversion, low energy consumption, low noise, and the ability to output ultra-high torque at low speeds to suit heavy loads. It offers wide speed adjustment, controllable start and stop, and precise response to load changes. Its compact design and high power density allow for easy adaptation to equipment layouts and can withstand complex working conditions such as high dust levels, strong vibrations, and high-pressure oil contamination, preventing insufficient power and ensuring stable equipment operation.
Compared to ordinary piston motors, this product uses high-quality materials and is precision-machined, strictly adhering to relevant industry standards. The pistons are made of GCr15 alloy steel (hardened and ground), the cylinder body is precision-machined from 45# steel, and the seals are made of FKM fluororubber for superior sealing. Manufactured through multiple precision processes, it features precise fit and minimal leakage, effectively solving problems such as low efficiency, insufficient torque, seal leakage, and short lifespan of ordinary motors, reducing maintenance costs, and precisely matching the hydraulic power requirements of engineering machinery.
