High-Power Rotary Motion with Variable Displacement for Demanding Hydraulic Drives.
A piston motor is a type of hydraulic motor that uses reciprocating pistons inside cylinder bores to convert hydraulic pressure into continuous rotary motion. Unlike gear or vane motors, piston motors handle much higher pressures and offer variable displacement options—meaning speed and torque can be adjusted on the fly. Yagang piston motors are available in axial piston (most common) and radial piston designs, with displacements ranging from small (10 cc/rev) to large (140+ cc/rev). They deliver smooth rotation at both low and high speeds, handle pressures up to 5,000 PSI, and provide high starting torque efficiency. Common applications include track drives on excavators, winch drives on cranes, conveyor drives in mining, and fan drives on off-highway vehicles. When a job needs serious power in a compact package, piston motors are usually the answer.
Piston motors pack more power per pound than other hydraulic motor types. Yagang axial piston motors use a rotating cylinder block and angled swashplate to convert linear piston motion into shaft rotation. This design delivers high torque output from a relatively small envelope—ideal for mobile equipment where every inch matters. Radial piston motors offer even higher starting torque for applications like auger drives or wheel motors on heavy machinery.
Fixed displacement motors run at a speed proportional to flow. Yagang offers variable displacement piston motors that let operators adjust the swashplate angle—changing the motor's displacement while the machine runs. Decrease displacement for higher speed (lower torque); increase displacement for higher torque (lower speed). This flexibility is invaluable for applications like hydrostatic transmissions, winches that need both fast spooling and heavy pulling, or mixer drums that change resistance mid-cycle.
Piston motors see tough service: long run times, pressure spikes, and sometimes poor filtration. Yagang piston motors feature hardened cylinder blocks, high-strength pistons with slippers, brass or composite valve plates for efficient porting, and tapered roller bearings that handle both radial and axial loads. Case drain ports prevent pressure buildup in the housing. These motors survive continuous operation at 4,000–5,000 PSI without losing efficiency or developing excessive internal leakage.
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.

Axial piston motors have pistons arranged in a circle parallel to the shaft axis. They are more common, compact, and efficient for most mobile and industrial applications (track drives, winches, fans). Radial piston motors have pistons arranged radially around a cam lobe—they deliver very high starting torque at low speeds but are larger and heavier. Choose axial for general use, radial for extreme low-speed high-torque demands.
Yagang piston motors cover displacements from 10 cc/rev to 140+ cc/rev for axial designs, and higher for radial models. Continuous operating pressure is up to 5,000 PSI (350 bar) with peak pressures up to 6,000 PSI. Speed ranges vary: larger displacements handle 1,000–2,000 RPM, while smaller displacements can reach 4,000+ RPM. Always check the specific model datasheet for exact ratings.
Yes. As an experienced OEM piston motor supplier, we produce motors that meet or exceed original equipment specifications. Our engineering team works from OE part numbers, sample motors, or customer drawings to replicate displacement, mounting flange (SAE or ISO), shaft configuration (keyed, splined, tapered), port sizes and orientation, and auxiliary options (speed sensors, parking brakes, flushing valves). We also offer reverse engineering for discontinued or hard-to-find models.
Our MOQ for standard piston motor models is typically 5–20 pieces, depending on displacement and configuration. For custom or OEM orders, we offer flexible MOQ arrangements—including single-unit prototyping or small-batch validation before full wholesale procurement. Lead time for stocked models is 3–7 days after order confirmation. Custom orders typically require 20–35 days based on complexity, quantity, and component availability.
Absolutely. We provide comprehensive private labeling solutions for B2B clients, including motor housing marking with your brand logo and part numbers, custom paint colors, and branded packaging. For high-volume wholesale partners, we can also offer custom nameplates, serial number tracking, and modified port or mounting configurations exclusive to your distribution channel.
