Cylinders allow hydraulic systems to use linear motion and force without mechanical gears or levers by transferring the pressure from fluid via a piston to begin operation. Hydraulic cylinders are at work in both industrial applications (hydraulic presses, cranes, forges, packing machines), and mobile apps (agricultural machines, construction equipment, marine equipment). And, in comparison with pneumatic, mechanical or electric systems, hydraulics can be simpler, stronger, and offer greater power. For example, Long Stroke Hydraulic Cylinder has about ten times the power density of an electric motor of similar size. Hydraulic cylinders are also available in a remarkable array of scales to meet an array of application requirements.

Selecting the right cylinder to have an application is essential to attaining maximum performance and reliability. This means taking into account several parameters. Fortunately, an assortment of cylinder types, mounting techniques and “rules of thumb” are for sale to help.

The 3 most common cylinder configurations are tie-rod, welded and ram styles. Tie-rod cylinders use high-strength threaded steel tie-rods, typically on the away from the cylinder housing, to supply additional stability. Welded cylinders come with a heavy-duty welded cylinder housing using a barrel welded straight to the final caps, and require no tie rods. Ram cylinders are simply the things they seem like-the cylinder pushes straight ahead using very high pressure. Ram cylinders are employed in heavy-duty applications and almost always push loads rather than pull.

For all sorts of cylinders, the crucial measurements include stroke, bore diameter and rod diameter. Stroke lengths differ from less than an inch to a few feet or even more. Bore diameters can vary from an inch up to greater than 24 in., and piston rod diameters vary from .5 in. to more than 20 in. In practice, however, the option of stroke, bore and rod dimensions might be limited by environmental or design conditions. For example, space might be too limited for your ideal stroke length. For tie-rod cylinders, increasing the dimensions of the bore does mean increasing the number of tie rods required to retain stability. Enhancing the diameter of the bore or piston rod is an ideal way to make amends for higher loads, but space considerations might not allow this, whereby multiple cylinders is usually necessary.

Mounting methods also play an important role in cylinder performance. Generally, fixed mounts on the centerline in the cylinder are perfect for straight line force transfer and avoiding wear. Common varieties of mounting include:

Flange mounts-Very strong and rigid, but have little tolerance for misalignment. Experts recommend cap end mounts for thrust loads and rod end mounts where major loading puts the piston rod in tension. Side-mounted cylinders-Easy to install and repair, nevertheless the mounts create a turning moment since the cylinder applies force to your load, increasing damage. To avert this, specify a stroke at least as long as the bore size for side mount cylinders (heavy loading has a tendency to make short stroke, large bore cylinders unstable). Side mounts need to be well aligned and also the load supported and guided.

Centerline lug mounts -Absorb forces on the centerline, but require dowel pins to secure the lugs to prevent movement at higher pressures or under shock conditions. Pivot mounts -Absorb force on the cylinder centerline and enable the cylinder change alignment in a single plane. Common types include clevises, trunnion mounts and spherical bearings. Because these mounts allow a cylinder to pivot, they should be used in combination with rod-end attachments that also pivot. Clevis mounts can be used in any orientation and are generally suitable for short strokes and small- to medium-bore cylinders.

Operating conditions-Cylinders must match a certain application regarding the level of pressure (psi), force exerted, space requirements imposed by machine design, and so on. But understanding the operating requirements is simply half the challenge. Cylinders should also withstand high temperatures, humidity as well as salt water for Air Cylinder Components. Wherever temperatures typically rise to greater than 300° F, standard Buna-N nitrile rubber seals may fail-choose cylinders with Viton synthetic rubber seals instead. When in doubt, assume operating conditions will be more rugged compared to they appear at first glance.

Fluid type-Most hydraulics use a form of mineral oil, but applications involving synthetic fluids, including phosphate esters, require Viton seals. Once more, Buna-N seals will not be adequate to handle synthetic fluid hydraulics. Polyurethane is also incompatible rich in water-based fluids including water glycol.

Seals -This is among the most vulnerable aspect of 2 Post Floor Clear Car Lift. Proper seals is effective in reducing friction and wear, lengthening service life, as the wrong kind of seal can lead to downtime and maintenance headaches.

Cylinder materials -The kind of metal utilized for cylinder head, base and bearing can easily make a significant difference. Most cylinders use SAE 660 bronze for rod bearings and medium-grade carbon steel for heads and bases, which is adequate for most applications. But stronger materials, including 65-45-12 ductile iron for rod bearings, provides a substantial performance rldvub for tough industrial tasks. The kind of piston rod material may be essential in wet or high-humidity environments (e.g., marine hydraulics) where17-4PH stainless steel could be stronger than the standard case-hardened carbon steel with chrome plating employed for most piston rods.
