Attachment types of series R2
The range of cylinders to ISO 6022 R2 series offers 7 different attachment types, based on the fulfillment of the required qualifications of your application area. In the following you will find a description on the basis of the application area and the installation location of how you can find the correct differential or Double rod cylinder and accessories.
For special applications, and stresses please do not hesitate to contact our technical office at any time at your disposal.

Main category of attachment types

Feet attachment

Cylinders with feet attachment are not able to absorb force along the rod axis, which leads to that the cylinder develops a rotatory force against the attachment screws.

At this attachment type, it has to make sure that the force, which acts on the ball joint, is reduced as much as possible. This type of attachment is only available in a design that equates the identification code 03 (not according to ISO 6022) and should only be used where the working pressure is less than 160bar.

Flange attachment
This attachment type especially lends itself for cylinders which have to upset forces along their own axis, and are therefore adequate for lineal movements.They are available in 2 different types, which are grouped in the following codes:

01 - Front flange (ISO MF3)
02 - Bottom flange (ISO MF4)

The choice of attachments depends not alone on the installation location, but depends mainly of reaction forces from acting on the cylinder depending on the working direction.

Trunnion attachment
Cylinders with trunnion attachments are suitable for pressure- and tension work in which the load must be transported in a curved movement and in which the forces must be absorbed along its own axis. Two forms of this type are available as rear and center trunnion, which are divided into the following codes:

Pivot pin
07 - clevis on bottom (ISO MP3)
08 - rod end on bottom (ISO MP5)

06 - trunnion middle (ISO MT4)

Rod attachment Double rod cylinder

Double rod cylinders are usually available with all attachments, the favorites are the following types:

07 - clevis on bottom (ISO MP3)
08 - rod end on bottom (ISO MP5)
