Swivel Cylinder Radial Piston Motors
(Beta Series 1)

Main characteristics:

• Due to the absence of lateral forces between the piston and swing cylinder, the Beta series hydraulic motor incorporates a design where the bottom of the piston engages in static pressure with the crankshaft through rolling bearings, reducing friction loss during torque transmission. This design imparts high mechanical efficiency and notable starting torque (achieving over 92% mechanical efficiency during startup).
• The inclusion of a flat distribution device in the Beta series ensures simplicity, reliability, excellent sealing, and minimal leakage. The plastic piston seal in the piston and swing cylinder contributes to high volume efficiency, reaching up to 98%.
• The structural modifications aimed at reducing friction loss and enhancing sealing performance result in improved low-speed stability. The motor can smoothly operate at conditions as low as 10 r/min, with a broad speed range (adjustable up to a ratio of 1000).
• Thanks to the close fit between the piston and bearing sets facilitated by card rings, the Beta series hydraulic motor can operate under suction conditions. Moreover, it can move freely at high speeBeta after the motor inlet port, demonstrating efficient operation.
• The Beta series hydraulic motor can withstand high pressures, reaching a maximum of 31.5 MPa. Its characteristics include a light reset, compact size, and high power.
• With a simple and well-designed structure utilizing large capacity bearings, the Beta series hydraulic motor is known for reliability, long lifespan, low noise, and the ability to handle radial forces on the drive shaft. Its direction of rotation is also reversible.
