A cylinder is a mechanical device for rotating a load. To mount a cylinder, you need a mounting bracket. There are various mounting brackets for cylinders available in the market. Some of the commonly used ones include tie rod mounts, eye brackets, rod clevises, and autoswitch bands. These mounting brackets help to install the pneumatic cylinders in the desired location.
The mounting brackets are used to couple the rod end and the mounting surface. They are available in a variety of dimensions. ISO 15552 and ISO 6431 define different mounting accessories and cylinder mounting brackets. You can purchase the mounting brackets that meet your specific needs. These accessories are interchangeable and easy to use. They are available for both ISO and non-ISO cylinders. To get the right mounting brackets, you need to know the dimensions of your cylinder.
A rod-end spherical eye for a pneumatic cylinder is a type of mounting attachment for linear loads. It is typically coupled to a piston rod and rotates with it. This type of mounting bracket allows the cylinder body to move, but the piston rod is sometimes misaligned. This can cause unwanted forces. Rod-end eyes can compensate for misalignment issues by tilting with cylinder motion.
Pistons are mounted inside a pneumatic cylinder. The piston is attached to a carrier where the load is mounted. The piston moves in a straight line and always towards the side of the chamber with lower internal pressure. A piston with a movable rod has a low profile and a small diameter. They are also suitable for applications with limited space. To maintain a pneumatic cylinder, ensure the components are accessible.
Another type of cylinder rod eye is non-repairable. These are designed for economy and do not need to be repaired, and their end caps are welded to the barrel. This type is cost-effective when a cylinder is not required to have a high service life. The end caps are typically made of stainless steel. A double rod end model also features long bolts that thread into the end caps. These types of mountings also tend to sway under a load.
The piston rod is larger than normal. This prevents buckling, which is a problem with long-stroke thrust applications. A stop tube limits the amount of side-loading a cylinder experiences in its extended position. The fixed clevis mount is usually a poor choice for cylinders with short strokes, because the rod is forced to move in two directions, leading to misalignment and unnecessary side-loading on the bearings. If your cylinder has a fixed clevis mount, you should look into a cap spherical bearing mount. These mounts are most appropriate for air or medium-duty hydraulic service.
A pneumatic cylinder is more flexible than an equivalent conventional coiled spring. This means that when it stretches due to a change in temperature or strain, it will elongate. In fact, a 6,000 psi pulse can stretch a steel cylinder 0.024 in, while a cast iron or aluminum cylinder can elongate up to 2.5 times that. This elongation is common for hydraulic cylinders and will eventually lead to a leak. If you do not get a new cylinder for your cylinder, consider changing the design.
Another type of piston is the double-acting cylinder. This design enables a pneumatic cylinder to retract faster than it extends. A double-acting cylinder is generally larger than a single-acting cylinder and has a bigger piston and a smaller diameter. It also requires a stronger cushioning system. In addition, double-acting cylinders have longer strokes. Hence, they are more expensive than single-acting cylinders.
Tie rod cylinders are the most common type of pneumatic cylinders. They have a rod that extends over end caps and is mounted on a surface or machine member. They absorb forces symmetrically and avoid the possibility of shear stress on the mounting bolts. They also have a smaller tolerance for misalignment. However, they may not be suitable for all applications. This means that you should use the proper cylinder mounting brackets.
A rodless cylinder is a type that has no rod and is used in low-pressure hydraulic service. These cylinders have a high breakaway force and can function in hazardous environments. Another type of rodless cylinder uses magnetic brake. This is designed for precise positioning and motion control. In addition, they do not require any maintenance or repairs. You can also use a rodless cylinder in combination with pneumatic directional control.
