• Arm cylinder is the top one, and it's usually be called as top cylinder;
• Bucket cylinder is the one that connects and controls the bucket.

Basic Requirements For Sealing Materials:

• Have certain mechanical properties, such as tensile strength, elongation, etc.;
• Appropriate elasticity and hardness, small compression set;
• High temperature and low temperature resistance, no decomposition or softening at high temperature, and no hardening at low temperature;
• It is compatible with the working medium, without swelling, decomposition, hardening, etc.;
• Good oxygen resistance and aging resistance, durable;
• Abrasion resistance, no corrosion to metal;
