Product Overview

 

The OMS 160 series is a hydraulic motor that adopts the mature and reliable "orbital cycloid" technology (i.e., Gerotor technology). This series achieves efficient power conversion within a compact structure, making it particularly suitable for equipment with limited space but requiring continuous and reliable power. The specific model you inquired about has a nominal displacement of 160 cm³, a maximum continuous operating speed of 470 RPM, and is standard-equipped with a 1-1/4 inch 14-tooth spline output shaft and a standard magneto mounting flange, providing an out-of-the-box, well-balanced drive solution for industrial, agricultural, and municipal equipment.

 

Features and Advantages

 

1. Balanced performance and wide applicability
◦ Ideal displacement and speed combination: The 160cm³ displacement combined with a maximum speed of 470 RPM enables it to provide considerable torque while meeting the working speed requirements of many devices. It avoids excessive enlargement of displacement to pursue low-speed and high-torque, achieving a good balance between efficiency and power.
2. Reliable and robust power interface
◦ 1-1/4″ 14-tooth spline shaft: Compared with flat keys, spline connections can transmit greater torque, have better alignment and fatigue resistance, and are a classic and reliable configuration for medium-sized hydraulic motors.
◦ Magneto mounting flange: This is a highly standardized industrial mounting interface, which can ensure fast and accurate positioning and rigid connection between the motor and the driving components, greatly simplifying the installation process and improving system reliability.
3. Inherent advantages of orbital cycloid technology
◦ Compact structure and high power density: There are few internal moving parts and the structure is simple. It is usually smaller in size than piston motors with the same displacement.
◦ High starting torque and good low-speed stability: It is very suitable for occasions requiring load starting and stable operation in the medium speed range.
◦ Strong anti-pollution ability and good durability: The requirement for oil cleanliness is relatively lower than that of some precision piston motors, and the maintenance cost is lower.

 

Application scenarios

 

With its balanced performance and standard industrial interfaces, this motor is highly suitable for the following equipment:
• Agricultural and garden machinery: driving the fertilizer discharge shaft of medium-sized fertilizer applicators, the conveying auger of harvesters, and the cutterhead of large mowers.
• Industrial transmission and conveying: driving the drive rollers of factory conveyor lines, the rotating main shafts of packaging machinery, and material mixers.
• Municipal and special vehicles: driving the medium-sized brushes of road sweepers, the spiral snow collectors of snow removers, and the traveling or slewing mechanisms of aerial work platforms.
• General industrial fields: serving as the direct drive source for equipment such as hydraulic winches, cable reels, and fans.
