The new square-profile barrel the PES III range of pneumatic cylinders offers cleaner lines for use in hygiene conscious environments.
The new square-profile barrel of Asco Joucomatic's PES III range of pneumatic cylinders offers the twin benefits of cleaner lines for use in hygiene conscious environments, and also the option of T slots or dovetail grooves to give OEMs the maximum choice and flexibility in respect of sensor mounting positions.
The PES III range is designed to provide the benefits of true European interchangability.
Offered in sizes from 32 to 100mm bore, it complies with all relevant European standards: VDMA, ISO and AFNOR.
This wide ranging compliance provides benefits to machine builders and equipment suppliers, as it helps them to achieve total conformity between their machine actuation systems and their customers' installed plant and equipment.
The combination of the new profile barrel and cavity-free end caps means that the PES design is one of the cleanest available; its uncluttered lines adding to the aesthetics of any machine.
At the same time, the new square barrel with its multi-groove configuration offers OEMs the flexibility to mount either Reed switches or magnetic detectors in almost any position along the barrel length, to meet specific design considerations.
Easy to maintain, the PES III range is designed for operation on dry filtered air.
Key to this operation is a low friction piston seal, which ensures low breakaway pressure and is insensitive to distortion or temperature differences (in the range -20 to +60C).
Other features of the PES III range include a one piece integrated tube sealing and cushioning unit, which allows easy cylinder maintenance.
The cushioning itself is provided by a cartridge-like system, which integrates a captive micrometric screw for high precision adjustment.
Several options are available to users of the PES range.
These include though rod versions, units with round aluminium barrels and tie rods; cylinders with dynamic rod locking devices and units equipped with Asco Joucomatic's patented Omega seal.
The Omega seal offers the benefit of constant low speed performance without slip stick or jerking.
The unique dynamics of the seal also ensure that high-speed performance is also excellent, at up to 3m/s.
The introduction of Omega extends the range of applications for pneumatic cylinders and means that in many low speed applications engineers can now employ the simplicity and the convenience of pneumatic actuation, and achieve considerable cost savings by not having to invest in hydraulic rams, pumps, valves relief valves etc.
