Where are telescopic cylinders used?
Telescopic cylinders are used in applications requiring long stroke but a short retracted length. The most common telescopic cylinder application is dump beds or trailers. They can fit between the frame rails of the chassis, but can extend far enough to dump even the longest beds. Telescopic cylinders use nested barrels, each like both a […]
5 tips for cylinder maintenance
Proper, consistent cylinder maintenance is necessary to keep your fluid power systems running smoothly and efficiently. Following these five tips is a step in the right direction. 1. Keep your oil clean. This should go without saying, but I wouldn’t have to say it if the majority of hydraulic failures weren’t still from contaminated oil. […]
Why are hydraulic cylinders used instead of pneumatic cylinders?
Pneumatic cylinders use compressed air to create linear force. Pneumatic pressure acts upon the piston of the cylinder at a level equal to that pressure times the area of the piston. Pneumatic systems rarely provide much more than a hundred pounds per square inch of pressure to the piston. The nature of compressed air allows […]
How do hydraulic cylinders fail?
Hydraulic cylinders fail by physical damage or by deterioration of their seals. Physical damage to a hydraulic cylinder is usually from an external source, such as another machine or a falling object. Damage can take the form of a bent rod or dented barrel, both of which could prevent the cylinder from stroking fully. Physical […]
What are hydraulic cylinders used for?
Hydraulic cylinders are used for creating mechanical force in a linear motion. A hydraulic cylinder is a tube capped at either end with a rod sticking out of one side. Attached to the rod, interior to the cylinder, is a piston. The piston separates the internal rod side from the internal cap side of the […]
How do you mount a hydraulic cylinder?
A hydraulic cylinder is mounted by attaching it at two points of the machine it’s creating linear force for. The rod end of the cylinder must be attached to the part of the machine receiving the force, i.e., the part of the machine you want to push on. The other mounting point is somewhere on […]
How do you specify a hydraulic cylinder?
Hydraulic cylinders are specified by the force required to be pushed and moved, and they are specified by their method of mounting. There are subordinate functions to be considered when specifying a hydraulic cylinder, such fluid type, column strength and material construction. However, 90% of cylinder applications are not exotic, and simply identifying force and mounting […]
How do hydraulic cylinders fail—contamination
Today’s fluid-power users, for the most part, are well aware that keeping hydraulic fluid clean is essential in preventing premature failures and unexpected downtime. Nonetheless, contamination remains a major cause of hydraulic-cylinder failure, particularly because it leads to seal failure and leaks. And it can come from several different and unexpected sources. Internal contamination is […]
