Overview

We offer several different mounting options for our pneumatic cylinders.  In the picture a “nose mount” cylinder is shown on the top and a “universal mount” is shown on the bottom.  A nose mount cylinder can only be mounted from the threads on top, a universal mount can be mounted from the top and bottom and can be pivoted from the rear.

Mounting Nut

·         Mounting Nuts allow you to mount a cylinder from the top or bottom.

·         Match the Mounting Nut thread size to that of the cylinder you will be using.

Jam Nut

·         Jam Nuts allow you to mount to the cylinder shaft end.

·         Standard use is to screw a Jam Nut onto shaft then screw on a shaft accessory such as a Clevis.  Jam nut is then tightened (e.g.  “jammed”) up against the Clevis to prevent it from unscrewing.

·         One Jam Nut is included with each of our cylinder shaft accessories (Clevis, Rod Bumper, etc.)

·         Match the Jam Nut thread size to that of the cylinder you will be using.

How proper mounting prevents premature cylinder wear

How you mount your cylinder affects both cylinder performance and cylinder life expectancy. That's because the wrong mounting or incorrect installation can result in side load. Side load occurs when a load is placed on the piston rod without guidance or support, or when the mounting and piston rod connection are misaligned. Side load creates excessive wear on the piston, piston rod, rod bearing and seals. Excessive wear leads to leakage and ultimately cylinder failure. By selecting the right cylinder mounting, you optimize cylinder strength, efficiency and alignment. Let's look at the two major types of mounts -- pivot and rigid -- and how they help avoid side load problems.

Pivot type mountings eliminate side loads when properly installed

There are several types of pivot mountings including clevis and rear pivot. To realize the benefit of a pivot type mounting, it's essential that a rod eye or rod clevis be used on the piston rod. Otherwise, it becomes a "rigid" mount cylinder, negating the benefit of the pivot. It's also important that the axis of all the pivot pins in a set are parallel or binding and side loading will occur. Long stroke pivot mount cylinders require stop tubes and dual pistons to spread out the distance between the rod bearing and piston to reduce the load at these two points.

Get maximum cylinder life with proper rigid mount cylinders

There are a number of rigid mounts available: side-mounted, nose-mounted, flange-mounted and face-mounted cylinders. Each must be carefully aligned with the direction of the load travel to avoid side loads. If, for some reason, proper alignment cannot be achieved, a rod end connection that allows for some lateral misalignment should be used.
