CYLINDERS

Quebec Hydraulique's QH™ THUMB Series Hydraulic Cylinders are specifically engineered for hydraulic thumb applications on both track-mounted and wheeled excavators.hese cylinders are designed to withstand the rigorous demands of heavy-duty operations, ensuring durability and reliable performance in challenging environments. Key Features:

• Induction Hardened Chrome Plated Rod: ach cylinder is equipped with an induction-hardened, chrome-plated rod, providing enhanced resistance to wear and corrosion, thereby extending the cylinder's service life.
  
  
• Heavy-Duty Piston Construction: he piston is both threaded and adhesively bonded to the rod, ensuring a robust connection capable of handling high-pressure scenarios.
  
  
• Fixed Cushions: arge fixed cushions at both ends of the cylinder are standard, aiding in the smooth deceleration of the piston and reducing internal stress during operation.
  
  
• Spherical Bearings: versized spherical bearings are standard at both ends, accommodating misalignment and reducing wear, which contributes to the longevity of the cylinder.
  
  
• High-Pressure Rating: esigned to operate at a working pressure of up to 5000 PSI, these cylinders are suitable for demanding hydraulic applications.
  
  
• Protective Transfer Hose Guard: he transfer hose is shielded by a thick steel guard, offering protection against external damage and ensuring uninterrupted hydraulic fluid flow. Specifications:
  
  
• Bore Sizes: vailable in bore sizes ranging from 2 inches to 6 inches, catering to various force requirements.
  
  
• Rod Diameters: od diameters vary from 1 3/8 inches to 3 1/2 inches, providing options for different load capacities.
  
  
• Stroke Lengths: troke lengths are customizable to meet specific application needs, ensuring optimal performance.
  
  
• Port Configurations: epending on the bore size, ports are available in ORB or Code 61 4-bolt flange configurations, facilitating easy integration into existing hydraulic systems. Applications:
