OVERVIEW
A gear motor is a hydraulic actuator that converts pressurized fluid into rotary mechanical power through a pair of meshing gears. Oil entering the motor acts on the gear teeth and is carried around the housing, creating torque that rotates the driven gear and output shaft.
Hydraulic gear motors are compact, economical, and mechanically simple, with dependable performance across a broad speed range. They are commonly used for auxiliary drives, conveyors, fans, spreaders, augers, and other mobile or industrial functions requiring robust fixed-displacement rotation.

Hydraulic Parts for All Construction Machinery
Pressurized fluid enters the gear motor and creates force on the exposed gear-tooth area. This force turns the gear set and output shaft, allowing hydraulic energy to drive rotating equipment without a direct electric or mechanical power connection at the work point.
A gear motor delivers useful torque from a small and lightweight package. It is well suited to fans, conveyors, augers, brushes, feeders, and other auxiliary mechanisms where installation space, straightforward mounting, and economical operation are important.
Many hydraulic gear motors can rotate in either direction when system flow is reversed, provided the selected model and drain arrangement permit bidirectional service. This allows simple forward and reverse control for conveyors, reels, doors, and positioning mechanisms.
Motor speed changes in proportion to supplied flow, enabling straightforward control with valves or variable pump output. Correct sizing keeps the motor within its permitted minimum and maximum speed while maintaining lubrication, efficiency, and stable operation.
The gear set, housing, bearings, shaft, and seals form a durable drive with relatively few components. With proper filtration, pressure protection, fluid viscosity, and alignment, a gear motor can tolerate frequent cycling and demanding mobile or industrial duty.

SUPPORT
Pressurized oil enters the motor and acts on the gear teeth, producing torque that rotates the gear set and output shaft. Fluid travels around the outside of the gears and exits through the return port after transferring hydraulic energy into mechanical motion.
A gear pump receives mechanical rotation and produces hydraulic flow, while a gear motor receives hydraulic flow and produces mechanical rotation. A motor may include different bearings, seals, porting, and pressure-balancing features to handle output loads and return pressure.
Key advantages include compact size, simple construction, competitive cost, broad availability, easy integration, reversible options, and dependable operation in mobile and industrial auxiliary drives. It is especially practical when advanced variable-displacement control is unnecessary.
Estimate the displacement from required torque, operating pressure, target speed, and available flow, then account for mechanical and volumetric efficiency. Confirm peak and continuous ratings, shaft and bearing loads, direction, ports, mounting, back pressure, duty cycle, and fluid conditions.
Absolutely. We provide OEM/ODM services and can manufacture according to your samples or technical drawings. Yes, there is a minimum order quantity, but it is flexible. Spare parts often have an MOQ of 1 piece, while complete pumps or motors vary by model—please inquire for details.
For in-stock items, we can ship within 3 days. For custom or non-stock items, delivery usually takes 7–15 days. We’ll confirm exact timing based on current inventory. We offer flexible shipping via express carriers (DHL, FedEx, UPS) and sea freight (CIF/FOB). We can also deliver to your designated freight forwarder in China.
We are a hybrid—both a manufacturer and a trading company. We produce our own products and also source specific components to offer complete solutions. We follow strict quality control protocols. All parts undergo CNC machining and heat treatment, and each is 100% tested before delivery to guarantee precision and reliability.
We accept T/T, L/C, Western Union, Alibaba Trade Assurance, and VISA. For new customers, we usually require full prepayment or a 30% deposit with the balance due before shipment. All products come with a 1-year warranty, provided they are installed and operated under normal conditions.
Tell us the model, application or target part number. Our sales team will help confirm specifications and quotation details.
