Re-Phasing Hydraulic Cylinders

Bailey International LLC offers a line of Chief TCR re-phasing hydraulic cylinders that are engineered to be a high-quality, value-priced solution for OEM agricultural applications such as seeding, tilling, fertilization, and harvesting where synchronization is needed to lift separate loads. Using a single power source and controlling mechanism, Chief TCR re-phasing cylinders will lift separate loads in synchronization without the use of flow dividers, creating cost and time savings, the company claims. Using a group of hydraulic cylinders connected in series, the hydraulic fluid is fed into the extend port of the master cylinder from the fluid power source. As the master cylinder’s rod extends, fluid is pushed out from the cylinder’s retract port into the extend port of the next slave cylinder in the series, creating motion in that cylinder. The company notes that it is critical that the volume of fluid pushed from the master cylinder matches the volume that is received into a slave cylinder. The volume differences do not match perfectly so there is always a slight variance between the different size cylinders, which is why a bypass port is added to the cylinder, allowing it to fully stroke before starting retraction or extension. The TCR is offered in a variety of standard sizes, as well as custom sizes if needed.
