piston.
One or more magnetic reed switches can be applied to the 
magnetic type.
For the magnetic reed switches type ASV see from page 1.110.1.
For mounting accessories see from page 5.30.1.
For rod clevis see from page 5.20.1.

How to order: 20/50 MDMXP

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

See page 1.1.3 to calculate the cylinder force.

Stainless Steel Cylinders ISO 15552

Bores from 32 to 200 mm

  

Double acting

New series of stainless steel 316 L cylinders conforming to 
ISO15552.
Round tube and external tie-rods, standard with adjustable 
cushionings.
Scraper ring in polyurethane specially developed for chemical 
and food industries.
The main features of this cylinder are the “clean” modern design 
and the attention to details. 
A particular attention has been given to the manufacture of the 
end caps; there are no external casting cavities, thus eliminating 
contamination traps.
In order to facilitate the replacement of the piston rod seal the 
nose has been developed for simple maintenances also on 
cylinders still mounted on a machine.

For the magnetic reed switches type ASV see from page 1.110.1.
For coupling cylinders/reed swiches/brackets see table on page 
1.120.5
For mounting accessories see from page 5.40.1
For rod accessories see from page 5.20.1.

The options can be combined (when this is possible).
The suffix of the options are to be added to the model number of the standard product, as shown in the following table.

Stainless Steel Round Cylinders

Bores from 32 to 63 mm

 

Double acting

New series of stainless steel round cylinder with bores from 
32 to 63mm., characterized by an essential design specifically 
developed to prevent the settling of impurities.

Cylinder body is smooth surface free of chamfers or cavities 
where dirt can settle. 
This series is fully in Stainless Steel AISI 316L.

These features make RXD cylinders specifically suitable for 
Food&Beverage, Chemical, Pharmaceutical and Medical 
industries and for all those applications where maximum  hygiene 
and cleaning are required, even in corrosive environments.

RXD Series are available in several configurations bespoke 
solutions are also possible.

Stainless Steel Round Cylinders

Bores from 32 to 63 mm

  

Double acting

Series of stainless steel cylinders not conforming to standards.
The heads are connected with the body through rolling: this 
guarantees perfect tightening.
Dumpers are in nitrile rubber to cushion the impact of the piston. 
RDMAX type are provided with adjustable cushionings at both 
ends (available only for bores 32 and 40 mm).
The standard cylinders are provided with rod nut.
One or more magnetic reed switches can be applied to the 
magnetic types.

For the magnetic reed switches type ASV  see from page 1.110.1
For mounting accessories 

see from page 5.35.1

For rod accessories
