Belparts excavator SY26 swing motor KSMN-16BD-21B slewing motor gearbox kit for Sany

The excavator swing motor is the core component responsible for the machine's 360° rotation, converting hydraulic energy into precise mechanical motion. Our cutting-edge swing motor series combines decades of engineering expertise with advanced materials science to deliver unmatched performance in harsh working conditions.

The slewing motor does not operate independently but works in coordination with various hydraulic control components, including:

• Main Control Valve: Regulates the direction and flow of hydraulic oil to control slewing speed and direction.

• Anti-shock Valve: Prevents sudden pressure spikes in the hydraulic system due to inertial impact when stopping rotation, protecting the motor and pipelines.

• Parking Brake: Typically uses a spring-applied, hydraulically released mechanism to ensure the excavator does not rotate unexpectedly due to external forces when parked.

• Make-up Valve: Prevents motor cavitation, ensuring smooth rotation.
