Extremely strong and versatile cylinders

The double-acting steel cylinders from LUKAS feature hydraulic retraction, making them more versatile than single-acting cylinders. They retract faster and can also be used for pulling work. In addition, thanks to a special overpressure valve, they also offer the user more safety.


  • Hydraulic piston retraction
  • For large loads up to 560 tonnes
  • Wide range of models available
  • Particularly robust and solid for challenging conditions
  • Overpressure valve protects users in the event of operating errors
  • Corrosion-protected thanks to baked enamel surfaces
  • Hard chrome plated pistons to prevent scoring and corrosion

LUKAS steel cylinders are mainly used in order to lift or precisely position heavy loads weighing up to 560 tonnes. Because of the wide range of models and their high level of standardisation, they can be integrated into existing systems at any time.


  • Standard external thread for easier assembly
  • Attachment holes in the cylinder base as standard
  • Standard with internationally typical screw couplers
  • With optional LUKAS quick coupler for integration in an existing 500-bar system
  • Internal thread in the piston rod for additional tools
  • Good lateral load tolerance
  • Full-load stroke limit
  • Scraper rings prevent pollution and wear
