How can I obtain three fixed positions using
Use two cylinders of the same stroke, joined
back-to-back or rod-to-rod and operate by
individual control valves.
Can a standard cylinder be operated in the slow
At very slow speeds hydro-pneumatic control is
What does ISO stand for?
ISO stands for International Standards
Organization an International body which
formulates various standards which equipment
should conform to allowing for interchange of
products between manufacturers.
Do cylinders and valves require lubrication?
Most Schrader cylinders and valves are
designed for use in non-lube operation. Airline
lubrication however will increase the service
life. If lubrication is used, it must be
maintained for the service life of the product.
Are your cylinders available in non-standard
Yes, we can make a cylinder to order in any stroke
length you require up to a design maximum.
What is the longest stroke we can use on a
This depends on mounting and loading style.
Do reed switches come with standard cylinders?
No, they need to be ordered separately. But these
cylinder to be called as reed switch operated
What force can a cylinder exert?
This depends on the air pressure applied to the
What is the maximum temperature at which
Schrader cylinders can operate?
The maximum for cylinders with standard seals is
80°C. For cylinders with Viton seals it is 180°C.
How can I slow down my cylinder?
By using flow regulators or speed controllers to
control the exhausting air from the cylinder thus
reducing the speed.
I want to stop a cylinder at some point in its
stroke - how can I do this?
You can use a 5 port, 3 position valve which has a
closed centre position. This will stop the
cylinder in a mid position however the positional
accuracy of using this method is not good. And
Other method is using positioner to control
cylinder stroke with respect to input signals.
I have a competitor's product part number, how
do I find the equivalent Schrader part number?
Please contact us and we'll be happy to advise you
of the most suitable equivalent for your
application. When selecting an equivalent there
are many features that may have to be taken into
consideration these include: function, conformity
to a standard, port connections, envelope size,
orientation, performance, duty, materials of
construction, pressure rating and power rating.
Do you offer cylinders that are interchangeable
with other makes or brands?
Yes, VDMA24562, ISO6431 and from 12mm to 200mm
bore. Also. A brand of Compact Cylinder
interchangeable with other brands.

How do Single Acting cylinders work?
They have a power stroke in one direction only
with a spring, gravity or other external force to
return the rod.
What is the advantage of using a Double Acting
As they use compressed air to power both the
outstroke and the in stroke, superior speed
control is possible. Double Acting cylinders
include Non-cushioned, and Adjustable cushioned
What are the main uses of Rotary Actuators?
Used for turning components, operating process

What is the most suitable cylinder to use in a
limited space where only a short stroke is
Compact Cylinder & "CA & CB Series
What are Bellows?
Bellows is used for to protect dust on piston rod.
Why use a cushioned
Cushioning protects a cylinder and load by
absorbing the energy at the end of stroke. This
results in progressive deceleration and gentle
contact between the piston and end cover.
I need a cylinder with a long stroke, how can I
be sure the piston rod won't buckle?
Some applications require very long stroke
cylinders. If there is a compressive axial load
applied to the piston rod, care must be taken to
ensure that the system parameters of rod length,
diameter and load are within the safety limits to
prevent buckling. In this case while manufacturing
