Hydraulic cylinders are used both for industrial purposes like in cranes, hydraulic presses, packing machines, forges etc. and for mobile applications like construction equipments, agricultural machines, and marine equipments, etc.

Cylinders permit hydraulic systems to supply force and linear motion without levers or mechanical gears. This happens by transferring force from the fluid through a piston to the operational point.

When compared with mechanical, electric systems or pneumatics, hydraulics can be more durable, simpler, and offer great force and strength.

For a case in point, a hydraulic pump carries about ten times more strength density than a similar sized electric motor. Hydraulic cylinders are moreover available in a remarkable array of scale to meet a broad range of application requirements.

Selecting the right kind of cylinder from the numerous options available among the variety of hydraulic cylinders provided by many hydraulic cylinder manufacturers is important for attaining maximum output and for attaining an utmost performance. That means one should take into consideration quite a lot of parameters before getting a cylinder. Fortunately, a multiple range of types of cylinders, their mounting techniques and "rules of thumb" are readily available.

Various Cylinder Mounting Methods

The mounting methods also act like an important part in the performance of a cylinder. By and large, fixed mountings on the centerlines of the cylinders are most preferred for straight line power transfer and to avoid wear and tear. Common types of methods of mounting include:

  • Flange mounts β€”The welding flange construction cylinder has flange mountings and it is a very strong and rigid option. But it has little acceptance for misalignments. Experts suggests cap end mount for rod end mounts and for thrust loads where major loading puts the piston rod in pressure or tension.
  • Side-mounted cylinders β€” These cylinders are easy to install and easy to service, but the mountings build a turning moment since the cylinders apply force to the load, increasing wear and tear. To evade this, define a stroke as long as the bore size of the side mounted cylinders. The side mounts need to be properly aligned. It is load supportive and guided appropriately.
  • Centerline lug mounts β€” These mounts absorb force on the centerline, however necessitate dowel pins to make safe the lugs to put a stop to movement at elevated pressures or underneath shock conditions.
  • Pivot mountings β€” These mountings soak up force on the centerline of the cylinder and let the cylinders change alignment at one plane. Common variety includes spherical bearings, trunnion mounts and clevis ones. Because these mounts let cylinder to pivot, these should be utilized with rod-end attachment that also pivots or spin around. Clevis mounts could be used in all orientations and are by and large recommended for shorter strokes and from small- to-medium bored cylinders.

The use of flange mounts in welding flange construction cylinders is the best solution generally, since the load is transferred throughout the centerline of the cylinder.
