LHA 25 double action hydraulic cylinder
– for high demands
On the following pages we present our LHA cylinder
range, a versatile type of cylinder designed for 250 bar
which is suitable for heavy-duty mobile and industrial
applications as well as harsh marine environments.
PMC Group’s cylinder programme
PMC Group offers a standard range of hydraulic cylinders, although much of our production
consists of customised special applications. We deliver cylinders with piston diameters of
20 – 800 mm and stroke lengths of up to 12 m, depending on the dimensions and design in
both black and stainless steel grades.
Standard cylinders
Special cylinders
Our LHA 25 cylinders are type-approved by DNV for
pressures up to 250 bar, depending on stroke length.
You can design an LHA 25 yourself using our drawing
generator at www.pmccylinders.se.
We manufacture special cylinders to match the customer’s
needs and wishes, e.g. for
Telescopic cylinders
We design and manufacture telescopic cylinders for all
industrial purposes.
– industrial applications,
– offshore and marine applications,
– energy power plants.
This includes stainless steel and subsea cylinders and
units with built-in transmitters and integrated valves.
Single action/plunger cylinders
We have delivered plunger cylinders for lifting bow doors
on ferries, ferry quay ramps, etc. for many years.
Our LHA 25 double action hydraulic cylinder is
presented on the following pages.
Most of our customers are to be found in four fields:
Energy, Offshore & Marine, Mobile Systems and Industry.
PMC holds a leading position in the energy field as
a supplier to the wind-power industry. Our industrial
customers are mainly steelworks, papermills and mining
companies who automate with the help of hydraulics.
In Offshore & Marine, PMC collaborates with many of
the world’s leading equipment manufacturers. Mobile
Systems comprise manufacturers of such things as forklift
trucks, mobile cranes, logging machines and mining and
construction equipment.
With our service organisation we can quickly be on the
spot to solve problems that arise in production. We
naturally stock spare parts and other components needed
to avoid needless stoppages and delays in production.

Double action hydraulic cylinder LHA 25
LHA 25, Linear Hydraulic Actuator
LHA (Linear Hydraulic Actuator) 25 is a result of a joint venture between the industrial and mobile communities in
Sweden and the offshore and marine communities in Norway. The result is a flexible cylinder designed for 250 bar, which
is ideal both for use in both industrial and mobile applications as well as in maritime surrundings.
The cylinder has been type-approved by DNV and has standard piston diameter dimensions of Ø 32 to Ø 400 mm.
