Synchronizing Rephasing Hydraulic Cylinders
PWM Synchronizing Hydraulic Cylinders are engineered to deliver precise, coordinated motion across multiple hydraulic actuators by utilizing advanced rephasing technology. This technology ensures that a master cylinder and one or more slave cylinders extend and retract in perfect synchronization, maintaining level positioning and balanced operation of heavy-duty equipment. Synchronizing cylinders are critical in applications where precise load distribution, consistent depth control, and smooth multi-point motion are essential—such as in agriculture, construction, mining, and material handling machinery.

- PWM’s standard synchronizing cylinders incorporate a precision-machined rephasing groove located at the piston’s full extension point. At this position, hydraulic fluid is allowed to bypass the piston seal, automatically correcting stroke variations across multiple cylinders in the system. Key benefits of this design include:
- Automatic Alignment – Ensures uniform cylinder extension and retraction, preventing uneven implement positioning.
- Consistent Depth Control – Maintains the desired working depth of wide or multi-point implements without operator adjustments.
- Self-Purging System – Allows trapped air to be efficiently expelled from the hydraulic system, reducing erratic operation and enhancing responsiveness.
- For applications requiring greater flexibility, PWM offers a ball-check rephasing cylinder option. This design incorporates a custom-machined port with a hardened ball mechanism that seals the rephasing groove when needed. This configuration provides:
- Controlled Retraction at Any Position – Allows operators to retract cylinders without reaching full stroke.
- Greater Versatility – Enhances system functionality in specialized equipment where mid-stroke synchronization and retraction precision are critical.
- Improved System Reliability – Prevents unintentional bypassing and ensures stable hydraulic control under varying load conditions.
- PWM Synchronizing Cylinders are designed and manufactured to meet demanding industrial performance requirements:
- Operating Pressure: Rated up to 3,000 PSI.
