Stronger. Smarter. Built for the forest.
Custom hydraulic cylinders for forest machines

Forest machines must operate reliably through continuous cycles and highly demanding conditions—ranging from extreme temperature shifts and heavy shock loads to abrasive environments and limited service access deep in the forest

Norrhydro designs and manufactures high-performance hydraulic cylinders for all functions in forestry machines, engineered to withstand dynamic loads, abrasive conditions, and continuous operation. Built for reliability in demanding environments, our robust solutions minimise downtime, extend service life, and keep your machines running when it matters most.

 

Engineered to withstand dynamic loads  

Long life-cycle for extreme conditions:
  • Verified fatigue calculations and optimised structural design
  • Heavy-duty seals, piston rod wiper for extreme conditions
  • Tested and field-proven floating cushioning to minimize loads’ effect for machine structure
  • Minimised downtime through extended service intervals 

Environmental and sustainability requirements:

  •  ISO 12944 Corrosion classification C4M, C5M by request  
  •  ISO 9227 Piston rod corrosion resistance up to: NSS1000 R10  
  •  Cold-resistant sealing option (down to -40 C)
  • Bio-oil compliant 

From roots to reach

Cylinders for every motion:

  • Crane
  • Steering
  • Grapple
  • Harvester head
  • Tilt
  • Cutting and measuring
  • Outriggers (integrated force measurement)
