Parts of a hydraulic cylinder

A hydraulic cylinder consists of the following parts: Cylinder barrel，Cylinder Bottom or Cap，Cylinder Head，Piston，Piston Rod，Rod Gland，Other parts，Cylinder bottom connection，Seals，Cushions. http://www.Emc-machinery.com

hydraulic cylinders should be used for pushing and pulling only. No bending moments or side loads should be transmitted to the piston rod or the cylinder. For this reason, the ideal connection of a hydraulic cylinder is a single clevis with a spherical ball bearing. This allows the hydraulic actuator to move and allow for any misalignment between the actuator and the load it is pushing.

Ningbo Eternal Machinery CO.,LTD. produce ELE Series Cylinder . This kind of durable high-pressure cylinder is designed for large and intermediate excavator with Maximum pressure of 35Mpa and operating temperature - 20℃ to 100℃.(for cold area - 40℃ to 90℃ )

EMC hydraulics & pneumatics can design cylinder according to our customers’ drawings and actual requirements. From die-casting,machining,honing,welding,painting to assembling,we have advanced facilities, first class technics and strict quality control system to guarantee superior quality , stable functions and durable feature . We have gained ISO2001:9000 system certification.

Features:

1. Small Size, Light weight, High intensity. High intensity,fatigue design,adapative cylinder designed as per loading frequency analysis are applied,and piston rod selection,processing and welding technology are inspected through ultrasonic falt detection. As it is designed for high pressure operation,it is featured in small size ,light weight,high intensity and high reliability.

2. Seal System. Seal rings of Parker as well as special designed sealing system are applied to prevent grit and dust,reduce oil leakage and obtain optimal piston rod oil film.

3. Cylinder body. The cylinder inner surfaces manufactured as per appropriate intensity and dimensions have excellent roughness and rigidity and better wearing capacity after roll finishing.

4. Piston rod. High frequency quenching followed by nickel chrome plating to improve rust proofing and wear and scar resisting performance.

5. Safety / buffer functions. Valves with slow stroke,counting balance and emergency close can be installed easily according to requirements. The concealed ones can absorb the impact of buffer device at the end of stroke.
