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, 24 and 25 Mini-Cylinders (DIN/ ISO 6432)
Series 16, 24 and 25 mini-cylinders are designed according to the European Standard Specifications CETOP RP52-P and DIN/ISO 6432.The choice of materials and other design features have provided the basis for a complete range of versatile and very reliable cylinders.The precise method of crimping the barrel at the head and cap ensures that all the parts are perfectly aligned. Since the Series 16 and 24 may operate at very high speeds, bumpers are attached to the piston as standard in order to reduce noice and wear resulting from high impact loads. Series 24 and 25 are suitable for mounting magnetic proximity switches.Series 25 has an adjustable pneumatic cushion and a magnetic piston. Various mounting accessories are available to enable the cylinders to function in a variety of applications.
Short-stroke cylinders Series RPA
Double-effect, magnetic
With hollow through rod and mounting stud
Bores: 20 and 30 mm
The Series RPA short stroke cylinders are double acting actuators with aluminium hollow through rod and mounting stud. Available in two sizes, Ø 20 and Ø 30 mm, with different strokes and dimensions of the mounting stud, these actuators are equipped with the non-rotating function of the rod.
The Series RPA are prepared for the mounting of magnetic sensors (Series CSD), in fact, on the external profile, along the cylinder tube, you can find sensor positioning slots.
Their compact and light design together with the adopted technical solutions make these cylinders suitable to be used, combined with suction pads, in End Of Arm Tooling (EOAT) systems, especially in the sector of plastic injection moulding.
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.
