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 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.
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.
Stainless steel mini-cylinders Series 94 and 95
Single-acting and double-acting, magnetic
Series 94: ø 16, 20, 25 mm
Series 95: ø 25 mm, cushioned
The Series 94 and 95 cylinders can be used in critical applications in which a high corrosion resistance is required (for example off-shore, marine, food).
Their construction enables the replacement of all seals.
Series 95 is normally equipped with adjustable end-stroke cushioning by means of a screw on the end block.
In addition both Series 94 and 95 are equipped with a mechanical cushioning in order to make the impact of the piston less noisy as it reaches the end of the stroke.
Stopper cylinders Series ST
Single and double-acting, magnetic, non-rotating
Sizes 20, 32, 40, 50 mm
The Series ST Stopper cylinders are pneumatic actuators with rod, complying with UNITOP and ISO 21287 standards, where rod and bushing have been specifically enlarged to ensure high resistance to radial loads and shocks.
These cylinders are available in two versions, double-acting and single-acting, and with rear spring.
The non-rotating rod version is also available.
The detection of the piston position is enabled by means of proximity switches (Mod. CST or CSH) which are mounted in slots along three sides of the cylinder profile.
It is possible to cover the slots with a proper profile (Mod. S-CST-500).
The high resistance to shocks and radial loads and the easy mounting makes Series ST particularly suitable for use in transport/conveyor lines where it is required to stop the transit of workpieces and workpiece-holder pallets.
