An arm cylinder is a type of hydraulic cylinder specifically designed to provide linear motion and force to the arms of various machinery, such as excavators, cranes, and robotic arms. These cylinders are crucial for enabling the movement and control of additional attachments or tools.



Arm cylinders incorporate various seals, such as piston seals and rod seals, made of wear-resistant materials like polyurethane and nitrile rubber. The cylinder body and threaded ends undergo fine surface treatment to improve wear resistance. Regular lubrication with suitable hydraulic oil is required to ensure smooth operation and longevity.
