Aluminum Actuator Inner Tubes

Actuator Inner Tubes: Critical Wear Surfaces for High-Performance Linear Actuation     Our actuator inner tubes serve as the precision-machined core of hydraulic and pneumatic cylinders, providing the durable, low-friction bore surfaces that ensure reliable piston sealing and efficient power transmission. Manufactured from high-grade steel substrates with advanced surface treatments, these inner sleeves deliver exceptional hardness, corrosion resistance, and dimensional stability under extreme pressure, temperature, and cyclic loading conditions.   Technical Specifications: Superior Surface Hardness: Induction-hardened or chrome-plated bore surfaces achieve 60+ HRC hardness ratings that resist scoring, galling, and abrasive wear from contaminated fluids Micro-Finish Bore Quality: Precision honing and roller burnishing create surface finishes below 0.2 μm Ra for optimal seal compatibility and minimal friction losses Corrosion-Resistant Coatings: Hard chrome, nickel-chrome, or…
