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, pivot and trunnion. 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. Trunnion
mounted cylinders require that pillow blocks or mated
bearings be fitted as close to the head of the cylinder
as possible to minimize bending stresses in the head.
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.

6025 Series
back
to top
The
Thomas 6025 Series is ideally suited for applications
that require low pressure, quiet operation, and long
life. Features and benefits include: low watts and
high efficiency, resulting in lower operating costs;
fewer moving parts, resulting in easier parts replacement
or rebuild; and it starts under pressure/vacuum, resulting
in less down time and more continuous operation.
