A stick cylinder controls the angular movement of the stick (arm) in an excavator, allowing the bucket to dig, lift, and handle materials. It extends or retracts to change the stick's position relative to the boom.
Typical bore diameters range from 80 to 200 mm, and rod diameters from 40 to 140 mm, per ISO 6020-2. These are reference ranges; the exact values depend on the excavator model and required force.
Common materials include high-strength alloy steel for the cylinder tube (e.g., 27SiMn), chromium-plated steel rod (e.g., 45#), polyurethane seals, and bronze bushings. Rod surface hardness is typically 50–60 HRC.
Selection requires matching bore, rod, stroke, operating pressure, and mounting type to the excavator's linkage and load requirements. Always verify parameters with the legal manufacturer or supplier for your specific application.
