Each piston is arranged radially. When pushing the piston, a compressed air pressure is transmitted to a crank through its rod, thereby rotating the crank. A rotary valve rotates in synchronization with this crank and supplies air to each cylinder or exhausts air from the cylinder.

• This air motor has been delivered to many customers over the years. The motor is mounted on a base or flange. Additionally, it has various options such as a brake, a reducer, a control valve, or other item.
• If the motor is used in a meter-out circuit (speed control by a throttle valve), strong engine braking can be expected.
• Each sliding part is subject to oil-bath lubrication. A line oiler is not fundamentally required, but in the case in which the motor is operated continuously, used infrequently, or used vertically (output axis in a downward direction), we recommend that the line oiler be placed on the air supplying side(primary ductwork).
• An air motor with a control valve enables a user to control its rotating speed or direction.
• The motor provides high torque in a low-speed range. Therefore, it is used for machines requiring high starting torque such as winch and hoist.
