Fixed Hydraulic Cylinders
Fixed hydraulic cylinders, or rams, are mechanical actuators that allow hydraulics and systems to apply linear motion and force. They transfer the pressure from hydraulic fluid through a piston to the point of operation. Fixed cylinders operate without mechanical gears or levers, and are fixed components of machinery. Portable cylinders, by comparison, are moveable versions for many one-off applications (classified as lifting or pulling types).
What are fixed hydraulic cylinders used for?
Fixed hydraulic cylinders have evolved into a vast array of configurations, sizes and special designs. Cylinders are used in both industrial applications (including hydraulic presses, cranes, forges, compactors and packing machines) and mobile applications (agricultural machines, construction equipment, marine equipment, etc.). The mobile machinery industry relies nearly exclusively on hydraulic cylinders for linear motion.
Types of fixed hydraulic cylinders
The three most popular types of construction are tie-rod, welded rod and telescopic. All of these can be either single or double acting. Each type uses a different methodology depending on how the end caps are attached to the cylinder barrel, as well as internal nuances. Fixed hydraulic cylinders are also available in an array of scales, bore sizes and stroke lengths to suit various applications.
