Compact Cylinders

Bores from 6 to 32 mm

  

Double acting

Series of compact cylinders double acting.

The barrel with grooves allow the mounting of the magnetic reed 
switches directly in the tube without brackets; the magnetic reed 
switches will not protrude out the barrel profile. One or more 
magnetic reed switches can be mounted on the cylinder.
Six sides of this cylinder can be attached unto objects for space-
saving purpose.

For the magnetic reed switches type ASC see from page 1.110.2.
For rod mountings see from page 1.85.1.

Short Stroke Cylinders

Bores from 12 to 200 mm

 

 

Double acting

See page 1.1.3 to cal-
culate the cylinder 
force.

Should you require 
intermediate strokes, 
the overall dimensions 
of the cylinder body will 
be those of the cylinder 
of the following stand-
ard stroke (in fact the 
intermediate stroke is 
obtained applying a 
distancer).

Series of short stroke cylinders with extruded aluminium profile 
barrel (up to the bore 100 mm) and fixing holes directly in the 
profile.
In the magnetic type, up to the bore 100 mm, the sensor can 
be fixed in the groove for sensor mounting by the bracket not 
included in the kit.
The sensor is to be fixed on the external tie rods with the bores 
125, 160 and 200 mm.
Standard elastic dampers (except the non magnetic type up to 
the bore 100 mm).
For the magnetic reed switches type ASV see from page 1.110.1.
For the bracket type AS108 

see page 1.120.1

For mounting accessories 

see from page 1.20.20.

For the rod with male thread 

see nipple page 1.20.20.

For rod accessories 

see from page 1.85.1.

How to order: 40 / 50 BDP

The options can be combined (when this is possible)

On request, they can be supplied

1.23.1

Compact Guided Cylinders

Bores from 10 to 63 mm

  

Double acting

Series of compact guided cylinders magnetic as standard.
A one piece body is provided with grooves allowing the mounting 
of the magnetic reed switch without further brackets; this makes 
the magnetic sensor not protrude outside the body itself.
The bottom plates are provided with elastic cushionings.

For the magnetic reed switches type ASC see from page 1.110.1.

How to order: 32 / 50 GEDBV

The options can be combined (when this is possible).

See page 1.1.3 to calculate the cylinder force.

Should you require intermediate strokes, the overall dimen-
sions of the cylinder body will be those of the cylinder with 
the following standard stroke (in fact the intermediate stroke 
is obtained applying a distancer).

On request, they can be supplied 

according to 2014/34/EU -
