This kind of hydraulic cylinder is especially designed for auto maintenance equipment, like 2 post lifts. In generally, our cylinder for 2 post lifts are most often used for the lifting, transferring and moving of auto parts. In comparison to other products with same parameters, hydraulic cylinders provided by Hoyo are featured by compact structure, light quality, reliable and high efficient performance, long lifespan, easy to install and convenient maintenance.
A smooth cylinder tube can effectively protect the inner sealed parts. That's why each of our tube must undergo strict examination and inspection, providing high smoothness and low friction coefficient.
Our guide sleeves can be disassembly independently and fast, making the maintenance convenient and economical.
Our piston rod is produced from carbon ally, processed by cylinder grinder and coated with hard chromium, providing a roughness degree of 0.2-0.4μm. not only that, all of our piston rods will shows no fatigue or wear under rated pressure.
The assemblage of all sealing elements is done in our clean room, allowing for good sealing performance. Our dust ring well protects our cylinder from being contaminated by liquids or wastes. All of our sealing elements can be designed and manufactured upon request.
We purchased a number of sophisticated and dedicate machines to complete mass production timely. These machines are included: CNC lathes, ultrasonic cleaning machines, coating lines, welding machines, assembling instruments, etc.
Hoyo is outfitted with numerous high precision testing devices and instruments, such as integrated test bench, durability test bench, hardness tester, thickness tester, roughness measuring instrument, ultrasonic fault detector, computer controlled pressure testing system, etc.
