In many applications, including on heavy equipment, machinery, and systems, the choice of the correct hydraulic cylinder will have a large impact on performance, efficiency and the life cycle of the cylinder and system. Poorly made or incorrectly sized hydraulic cylinders are more likely to fail, which can cause excessive downtime, loss of product and even the risk of damage or injury.
A single acting cylinder is an effective option in many applications. The term “single acting” refers to the fact they hydraulic fluids only work on one side of the piston, to push the rod up and out of the cylinder. The return of the rod into the cylinder can be accomplished by various options, but typically by the weight of the load or springs within the cylinder housing.
To this end, there is only one hydraulic port in the cylinder and one hydraulic hose to the cylinder from the pump. This reduces the number of parts and components on these cylinders, plus it makes installation easier in many different applications.
Design Considerations
As with any type of cylinder, there are multiple factors considered in the design. The weight, the angle and the actual physical installation of the cylinder in relation to the load and the equipment have to be considered.
For extended lift or push abilities, a telescoping single acting cylinder may be the best option. These cylinders, with multiple sections of the rod, are able to extend the lifting or pushing ability substantially more than found with a traditional cylinder.
Working with a specialized company manufacturing customized single acting cylinder models is the best option. These professionals can design the cylinder to meet the specific needs, either for a new piece of equipment or machinery or to replace an existing cylinder with may be failing or may have failed.
