Product catalog summary
Overview: This document provides technical specifications and operational guidelines for RXD and RXS pneumatic cylinders, focusing on their braking systems and connection configurations.
Specifications:
  • The RXD and RXS cylinders are designed for precise stopping, quick response, and smooth starts.
  • They utilize 5/2 solenoid valves to manage pressure and ensure optimal performance.
  • Components include double and single acting braking devices, flow regulators, shuttle valves, and pressure regulators.
Operational Procedures:
  • For RXD (Double Acting), air is supplied to port AA to apply the brake and removed to release it at port BB.
  • For RXS (Single Acting), the brake is applied by default and released by supplying air to port BB.
  • Brakes can be applied at any point along the cylinder stroke in both directions.
Performance Data:
  • Speed and stopping tolerances vary between RXD and RXS, with RXD offering tighter tolerances.
  • Standard bore sizes range from 32mm to 100mm, with corresponding stroke lengths.
Technical Features:
  • Constructed with aluminum alloy end caps, chromium-plated steel piston rods, and stainless steel tie rods.
  • Operating temperature ranges from -10°C to +80°C, with a pressure range of 2 to 10 bar.
  • No lubrication is required, and the medium used is filtered air.
Additional Information:
  • Special configurations are available upon request, including integration with twin rod cylinders and torque actuators.
  • Minimum unclamping pressures are specified for both RXD and RXS models.

A-79 CILINDRI PNEUMATICI PNEUMATIC CYLINDERS EXAMPLE FOR RXD - RXS CONNECTION / ESEMPIO DI COLLEGAMENTO PER RXD - RXS This system realizes the best conditions for the exploitation of RXD - RXS cylinders operating features: speedy stop, stopping accuracy, starts without jerks. Making use of the two valves 5/2 (4-5) besides taking advantages of “closed centres in pressure” system, we have the possibility to allow the inlet pressure of the rear port to be lower, to compensate for the piston-rod. Con questo sistema si realizzano le migliori condizioni per lo sfruttamento delle caratteristiche dei cilindri RXD - RXS: velocità di intervento, precisione nell’arresto, partenze senza scatti. L’impiego di due valvole monostabili (4 e 5) oltre ad ottenere i vantaggi del sistema “centri chiusi in pressione”, offre la possibilità di alimentare la camera posteriore del cilindro da bloccare ad una pressione inferiore per compensare la differenza di sezione di spinta dovuta allo stelo.

A 7 3 2 2 4 5 6 With the Double Acting brake unit, type RXD, the brake is applied by supplying air to port AA.To release the brake, air must be removed from port AA and applied to port BB.The clamping force of this unit is directly proportioned to the supply pressure at port AA. With the Single Acting brake unit, type RXS (see fig. 1), the brake is normally applied to the piston-rod with a campling force as shown in the table (see page A-79). To release the brake, air is supplied to port BB. In both DA & SA versions the brake may be applied at any point of the cylinder stroke, in every direction of the piston rod. Il bloccaggio dello stelo, nel cilindro RXD con dispositivo a doppio effetto, avviene inviando aria compressa all’ingresso AA in modo continuativo. Lo sbloccaggio si effettua mediante l’invio di un impulso d’aria all’ingresso BB. La forza di bloccaggio sarà direttamente proporzionale alla pressione di ingresso in AA. Nei cilindri con dispositivo di bloccaggio a semplice effetto RXS (vedi fig.1 ), lo stelo in assenza d’aria è bloccato con una forza costante come indicato nella tabella esplicativa (vedi pagina A-79). Lo sbloccaggio si effettua mediante invio continuativo di aria compressa all’orifizio BB. Il bloccaggio dello stelo, in tutte le versioni, può avvenire in qualsiasi punto della corsa ed in entrambe le direzioni. RXD .. / ... RXS .. / ...
