JB/T 8728-2010 (English Version) PDF

Scope: This standard specifies crankshaft connecting rod radial piston motors, crankshaft connecting rod radial piston motors, crankshaft swing cylinder radial piston motors, inner curve radial piston motors, and radial steel ball motors (inner curve radial ball motors). Structural types, basic parameters, technical requirements, test methods, inspection rules and markings, and packaging of six low-speed and high-torque hydraulic motors, including piston motors) and double-swashplate axial piston motors. This standard applies to the above-mentioned low-speed and high-torque hydraulic motors that use hydraulic oil or other mineral oils with equivalent performance as the working medium. Other structural types of low-speed and high-torque hydraulic motors can be used as a reference.
