Reliable, Compact, and Efficient Rotary Power Solutions for Demanding Industrial and Mobile Hydraulic Systems.
A hydraulic gear motor is a mechanical actuator that converts hydraulic pressure and flow into rotary motion and torque. By utilizing the synchronized rotation of internal gears, these motors provide a cost-effective and dependable method for driving conveyors, fans, agricultural machinery, and construction equipment. Unlike more complex motor types, the gear motor is prized for its simple design, high tolerance for fluid contamination, and ability to operate efficiently at high speeds.
At Yagang, we specialize in manufacturing rugged gear motors engineered from high-strength cast iron or aluminum alloys. Our units feature precision-ground gears and advanced sealing technology to ensure maximum volumetric efficiency and a long service life. Whether you require a single-rotation or bi-directional motor, our standard and custom configurations are designed to integrate seamlessly into your hydraulic circuits, delivering consistent performance in even the harshest operating conditions.
Our hydraulic gear motor models deliver impressive rotary power in a compact footprint, making them the preferred choice for mobile equipment where space is at a premium and weight reduction is critical.
Thanks to their simple, robust internal geometry, these motors are less sensitive to fine particulate matter in the hydraulic oil than piston or vane motors, significantly reducing unplanned downtime and maintenance costs.
Every unit is equipped with high-pressure shaft seals and reinforced bearing plates, ensuring reliable startup even under cold-start conditions and preventing internal leakage during high-pressure continuous operation.
Yagang hydraulic cylinders ensure precision motion control for automated production lines. They address the need for reliable, low-maintenance actuation in packaging, handling, and assembly systems, minimizing downtime in continuous operations.
For high-speed, repetitive cycles in CNC and stamping equipment, Yagang hydraulic cylinders provide exceptional accuracy and rigidity. They are engineered to combat wear and maintain positioning precision over long service life.
As the core power component, Yagang hydraulic cylinders deliver consistent, high-force output for molding and forging. They are built to withstand extreme pressure spikes and ensure stable platen movement, crucial for product quality.
In high-heat, high-shock mill environments, Yagang’s heavy-duty hydraulic cylinders offer robust performance for rolling and handling. Their design focuses on heat resistance and structural integrity to withstand punishing conditions.
Subjected to extreme abrasion and shock loads in crushers and kilns, Yagang hydraulic cylinders are built for toughness. Their robust design prioritizes seal protection and piston rod strength to maximize uptime in the harshest environments.
Our process is built to ensure clarity, efficiency, and full client satisfaction, solidifying our role as your reliable hydraulic partner.
Our technical team assists you in selecting the precise standard cylinder model that meets your required bore, stroke, mounting style, and pressure ratings, ensuring optimal fit and function for your machinery.
Utilizing ISO-compliant quality systems, we manufacture your standard cylinders. Every unit undergoes rigorous in-house testing, including static pressure hold tests and dynamic cycle tests, exceeding industry requirements.
We manage efficient packaging and logistics, providing fast and secure shipping globally. Our focus on rapid delivery minimizes your downtime and accelerates project timelines.
We offer comprehensive technical documentation and readily available remote support for troubleshooting and maintenance guidance, ensuring sustained peak performance throughout the cylinder’s lifespan.
While they look similar, a gear pump converts mechanical energy into hydraulic flow, whereas a hydraulic gear motor does the opposite—it uses hydraulic flow to generate rotary mechanical power. Our motors are specifically designed with internal drainage and specialized seals to handle the back-pressure inherent in motor applications.
You need to identify your required output torque (Nm or in-lbs) and the desired RPM at your available system pressure (PSI or Bar). Our technical team can help you calculate the necessary displacement to match your pump's flow rate.
Absolutely. As an experienced manufacturer, we can customize mounting flanges (SAE A, B, or C), shaft types (splined, keyed, or tapered), and porting options to match your existing equipment or OEM specifications perfectly.
For standard hydraulic gear motor models in stock, we ship within 3–7 days. Custom OEM orders or large wholesale batches typically require 15–25 days, depending on the complexity of the housing or shaft modifications.
We provide a 12-month comprehensive warranty, 24/7 technical consulting, and ready-to-ship seal kits. For large-scale partners, we also offer private labeling and custom packaging to support your local brand presence.
