Series CGPM are self-centering, parallel
grippers, guided by means of an H-shaped sliding guide.
The series is available in 5 sizes with different strokes.
Thanks to the materials and surface coating used, the gripper offers a high performance over time, enhanced reliability and protection against the entrance of impurities.
grippers, guided by means of an H-shaped sliding guide.
The series is available in 5 sizes with different strokes.
Thanks to the materials and surface coating used, the gripper offers a high performance over time, enhanced reliability and protection against the entrance of impurities.
Extreme compact dimensions, high repeatability and the opening and closing speed make the Series CGPM particularly suitable in applications like pick & place, insertion and machine tending, that are typically found in the Assembly sector.
These pneumatic grippers are mainly used on automatic machines that require high production cycles and very precise positioning.

Compact cylinders Series 31
Double and single-acting, double-acting non-rotating, magnetic
Ø 12, 16, 20, 25 mm
Ø 32, 40, 50, 63, 80, 100 mm UNITOP
The compact dimensions allow Series 31 single and double-acting magnetic cylinders to be installed within confined spaces.
These cylinders are suitable for use with feet, brackets.These cylinders are available in 10 different bore sizes from Ø12 to Ø100.
The guides are inserted in the external profile parallel to the sliding axis on three sides.
These guides are used to locate the switches that sense the piston position.
The construction design of these cylinders provides excellent axis stability.
They are available either with a male or female thread.
These cylinders can be supplied in W version for high temperatures (140°C).
This last version is not magnetic.
Cylinders with integrated guide Series QC
Double-acting, magnetic piston, guided
ø 20, 25, 32, 40, 50, 63 mm
These actuators, suitable for use in very limited space, are available in two versions.
- QCT version: with sintered bronze bushes, suitable when the side loads applied to the cylinder are high.
- QCB version: with linear ball bearings, suitable for high precision and fast cycling applications.
Series 16, 23, 24 and 25
Series 16: Ø 8, 10, 12 mm - non-magnetic
Series 23: Ø 16, 20, 25 mm - magnetic, auto-cushioned
Series 24: Ø 10, 12, 16, 20, 25, 32 mm - magnetic
Series 25: Ø 16, 20, 25, 32 mm - magnetic, cushioned
Series 16, 23, 24 and 25 mini-cylinders are designed according to ISO 6432. It is possible to choose from three different types of cushioning: mechanical (standard bumper on Series 16 and 24), adjustable pneumatic cushioning (Series 25) and pneumatic auto-cushioning (Series 23).
This last version, thanks to a patented system, automatically adjusts the cushioning in order to provide optimal deceleration during the entire cushioning phase.
The cylinder enjoys smooth, jolt-free movement, reducing vibrations and noise, while also guaranteeing high reliability and constant performance over time.
The adopted technical solutions and the choice of materials have provided the basis for a complete range of versatile and very reliable mini-cylinders.
They are suitable to be used in a multitude of industrial applications, especially where operating conditions undergo changes over time like for example wear of machine components.
Various mounting accessories are available to fix the cylinders in different ways.
Short-stroke cylinders Series QN
Single-acting, non magnetic
ø 8, 12, 20, 32, 50, 63 mm
Series QN single-acting short-stroke cylinders have been designed so that they can be installed in very small spaces.
Due to the compactness and sturdiness of these cylinders, they are mainly suitable for positioning and locking.The available strokes are indicated in the tables.
Stainless steel cylinders Series 97
Single- and double-acting, cushioned, magnetic.
Ø 32, 40, 50, 63 mm
Series 97 stainless steel cylinders can be used in critical applications where a high level of corrosion resistance is required (for example: off-shore, naval, food industries).
These cylinders are normally equipped with end-stroke cushioning which can be adjusted through a screw on the end block.
In order to quieten the impact of the piston on the end block, these cylinders are also equipped with mechanical cushioning.
