Anti-rotation guide units Series 45

Suitable for cylinders:
  • DIN/ISO 6432 (Ø 12, 16, 20, 25 mm)
  • ISO 15552, previous DIN/ISO 6431 (Ø 32, 40, 50, 63, 80, 100 mm)
Series 45 guide units can be used with all DIN/ISO 6432 cylinders of Ø 12 ÷ Ø 25 and ISO 15552, previous DIN/ISO 6431, cylinders of Ø 32 ÷ Ø 100. They have been developed in order to prevent piston rod rotation and can support possible radial loads. Series 45 guide units are available in three different models depending on the applicable loads. The UT and HT guides with crawling supports are self lubricating, while HB guides have a ball bush. To ensure the right choice of the loads in relation to the stroke, please refer to the graphs. The shorter the stroke the higher will be the applicable loads.

Compact cylinders ISO 21287 Series 32

Single and double-acting, non-rotating, auto-cushioned ø 12, 16, 20, 25, 32, 40, 50, 63, 80, 100, 125 mm
Series 32 cylinders, thanks to their compactness, are suitable for installation in confined spaces. Being in compliance with the ISO 21287 Standard, the cylinders Series 32 can be used in conjunction with mountings/accessories suitable with ISO 15552 standard.

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.

Compact cylinders Tandem and Multi-position versions Series 32

Double-acting, magnetic ø 25, 40, 63, 100 mm
Thanks to their great compactness Series 32 cylinders, Tandem and Multi-position, are suitable to be installed within confined spaces and can be used with the same mounting elements of other standard cylinders ISO15552. The Tandem version enables to obtain up to 2 times the thrust force of a normal cylinder (standard traction force), while the Multi-position version can obtain up to three positions with one cylinder only.

Compact cylinders, Tandem and Multi-position versions Series 31

Double-acting, magnetic Ø 12, 16, 20, 25, 32, 40, 50, 63, 80, 100 mm
The compact dimensions allow Series 31 cylinders to be installed within very small spaces. These cylinders are suitable for use with feet, flange and trunnion mountings. In order to complete the compact cylinder series, two new versions have been introduced: tandem and multi-position. The new Tandem version with 2, 3 or 4 stages generates a thrust force which is 2, 3 or 4 times that of the normal cylinder (standard traction force). The Multi-position version allows a maximum of 3 different positions which are determined by the stroke of the individual actuators.

Compact mini-cylinders Series 14

Single-acting Bores ø 6, 10, 16 mm and strokes 5, 10, 15 mm
With super-rapid fitting ø 4 and M5 port
Series 14 single-acting compact mini-cylinders have been designed for installation in very small spaces. The design allows the cylinders to be inserted into threaded blocks incorporated in the machine. All the minicylinders are supplied with a super-rapid fitting incorporated in a tube ø 4 or with a M5 thread. They are available in two versions with either a threaded or a non threaded piston rod.

Cylinders aluminium profile Series 41K

Double-acting, cushioned, magnetic Ø 160 - 200 mm
Series 41K cylinder comply with the ISO 15552 standard and can be assembled with the entire range of standard accessories. The mounting brackets used on the end-blocks tube are designed in an extremely secure way, making use of cylinder tie-rods positioned internally and not visible on the assembled cylinder. This cylinder series is normally equipped with adjustable endstroke cushioning by means of a screw positioned on the end-block.

Cylinders Aluminium profile Series 61

Single and double-acting, magnetic, cushioned Standard, low friction, low temperatures and tandem versions Ø 32, 40, 50, 63, 80, 100, 125 mm
Series 61 cylinders comply with the ISO 15552 standards and can be assembled with the entire range of standard accessories. A permanent magnet, mounted on the piston in these cylinders, enables information to be received regarding the piston position by means of proximity switches mounted in grooves along the cylinder profile. These grooves can be covered with a slot cover profile.This cylinder series is equipped with adjustable end-stroke cushioning. Moreover, they are equipped with a mechanical cushioning in order to reduce the impact of the piston as it reaches the end of the stroke.

Cylinders ISO 15552 Series 63

Single and double-acting, magnetic, cushioned Ø 32, 40, 50, 63, 80, 100, 125 mm
The Series 63 pneumatic cylinders have been developed to guarantee high performance and versatility. Thanks to a new system of adjustable pneumatic cushioning, the cylinders can always guarantee the best regulation whilst significantly reducing noise caused by the impact of the piston on the end block.Besides the standard version, which can be used in many sectors, specific solutions have been developed for applications such as food processing, agriculture, in tensioning, dosing systems and dancer arms for winding applications. There are also versions for demanding application environments, capable of withstanding extreme temperatures, corrosive atmospheres etc.

Cylinders Series 40K

Double acting, cushioned, magnetic Ø 160 - 200 - 250 - 320 mm
Series 40K cylinders comply with the ISO 15552 standard and can be assembled with the entire range of standard accessories. A permanent magnet on the piston of these cylinders is able to send, through proximity switches mounted on the cylinder sliding axis, electrical signals to indicate its position.This series is normally equipped with end-stroke cushioning which can be adjusted through a screw on the end block.

Cylinders Series 42

Single and double-acting, magnetic, cushioned Ø 32, 40, 50, 63 mm
Series 42 cylinders have been designed without tie rods to assure an extremely clean design. Stainless steel has been used for the tube and the rod, while the end cover is made in anodized Aluminium. These cylinders are normally equipped with adjustable end-stroke cushioning and with a mechanical cushioning in order to make the impact of the piston less noisy as it reaches the end of the stroke.

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.
Both versions are equipped with fixed cushioning to prevent direct impact with the end covers. The design of the cylinder body allows the mounting of the cylinder using either top, bottom or side faces. Several “T” shaped grooves in two faces allow sensors to be fitted in a number of positions.
