DALLAST customized production of various welded cylinders with spherical eye, please contact our sales team and send us your technical parameters, specific requirements or product drawings. Our team of professional technical engineers will accurately express our welded cylinders with spherical eye technical parameters on the drawings.
Sealing system
Relying on a unique sealing system designed to overcome the special field conditions of the cylinder, Prevents destructive pollution of hydraulic cylinders by soil dust. While thoroughly solving the leakage outside the hydraulic cylinder, the piston rod is ensured to obtain the best lubricating oil film, which prolongs the service life of the sealing.
Cylinder Body/Tube
Use special materials to achieve good surface finish and hardness through cold extrusion and tumbling. It has achieved lightweight and high pressure design requirements.
We generally choose materials with higher tensile strength and yield strength, eg: quenched and tempered 27simn, or cold drawn tube ST52-3, or Q345B,
Want to know the strength comparison between various materials 27sims/ST52-3/ Q345B ………? Please contact our technical department, who can teach you how to choice the material as a hydraulic cylinder tube in different environments.
Piston rod
Based on medium frequency quenching, the corrosion resistance of the piston rod is improved by double-layer bimetal plating (hard chrome plating + nickel plating).
FAQ
Belarus customers consulted with us about welded cylinders with spherical eye
Q: How do I know about the production?
A: We will double confirm your requirements and send you the sample before the mass production.
During the mass production, we will keep you informed of any progress. Besides, we will
do 100% quality inspection before shipment.
Q: How can I know the status of my products?
A: We will keep you posted for the production progress like material purchasing, production status, delivery time, tracking number until you received the products.
Q: How does the control the quality?
A: 1) During processing, the operating machine worker inspect the sizes by themselves.
2)After finished the first whole part, will show to QA for full inspection.
3)Before shipment, the QA will inspect according to ISO sampling inspection standard for mass production. Will do 100% full checking for small QTY.
4) when shipping the goods, we will attach the inspection report with the parts.
Q: What are the reasons for the frequent bending of the piston rod of the excavator cylinder?
A: More, you have to use the impact hammer. Basically, you must analyze the force.
When the cylinder is working with thrust and tension, it cannot receive momentum.
