Festo ADNP Standard Cylinder

The Festo standards-based cylinder ADNP is manufactured from high-quality technopolymer (a polyarylamide compound reinforced with 50% glass fibre). Its compact design (50% less compared with large standard cylinders) means it can be used even in tight-fitting spaces.

Its minimal weight makes it ideal for mounting on moving machine parts. It is ideal, if no special functionality such as offered by the Festo ADN / AEN standard cylinder family is required. It is a Compact cylinder with ISO 21287 standard dimensions


  • Stroke lengths from 5 mm to 80 mm
  • Innovative technology for maximum speeds
  • Polymer end caps with integrated fittings — faster, lighter and low cost
  • Flexible in use thanks to customised variants
  • Emergency cylinder assembly service available

The strength of the ADNP lies in the detail. Take the patented 3K piston, for example: this piston has excellent running characteristics and outstanding cushioning characteristics in the end positions for high speeds and machine cycles. The compact 3K piston also saves fitting space, which means a longer piston rod bearing can be used. The result: greater guiding precision and higher maximum lateral forces.

Double-acting operation

  • Operating medium: dried compressed air, lubricated or un-lubricated
  • Basic weight for 0 mm stroke: 115 g
  • Operating pressure: 0.6 bar to 10 bar
  • Ambient temperature: -10° C to 60° C

Technopolymer construction offers key advantages when it comes to reducing costs while maintaining consistent quality:

  • Very high rigidity
  • Lower weight than aluminium
  • Resistant to oil, acids, alkalis, and solvents
  • Excellent surface finish
  • Reverse bending strength is higher than that of certain light metal alloys
