Series Advantages
Product Advantages
Superior Efficiency: The motor features a static pressure balance structure between the shaft joint and the connecting rod. This perfectly smooths friction, decreases heat loss, and significantly increases both mechanical and starting efficiency.
High Working Pressure: Thanks to the reduced friction and advanced internal balancing, the hydraulic radial piston motor can comfortably sustain higher working pressures.
Extended Service Life: The main shaft employs a separated (fissam) structure, and all key components undergo special heat treatments using premium materials to drastically prolong the motor's lifespan.
Direct Interchangeability: Specifically designed to mirror the dimensions and performance of the KAWASAKI-STAFFA HMB series, meaning you can swap out old motors directly without expensive system redesigns.
