Crawler Excavator Parts
This swing motor adopts advanced swash plate piston structure, with standard displacement and 250–350 bar working pressure, delivering powerful rotary torque and stable 360° slewing performance. Built with high-strength alloy shell and precision internal valve plate, plunger and bearing parts through heat treatment and fine machining. Integrated buffer valve, balance valve and mechanical brake structure effectively reduce hydraulic impact and ensure smooth start and stop. It features standard mounting flange and spline specification, high interchangeability, low internal leakage, stable operation under high temperature and heavy-load environments, and effectively improves working efficiency and service life.
Original matching specification for SANY SY335 series, accurate mounting size and direct replacement.
Large-torque piston structure provides strong rotary power with smooth and stable slewing performance.
Integrated buffer and brake design reduces impact, minimizing swing drift and improving operating comfort.
High-strength alloy housing and precision internal components enhance wear resistance and long service life.
Strict manufacturing process controls internal leakage, maintaining high efficiency under continuous heavy-duty operation.
Excellent environmental adaptability, stable performance in high temperature, dusty and frequent operation scenarios.
