5. 3/8NPT oil inlet design is more conducive to piston retraction
6. Note: This product is a non-standard product, all such products
are customized according to user requirements Technical data is for
reference only
Common knowledge of hydraulic cylinders
1. Calculation method of hydraulic jack: hydraulic area x working
pressure
2. If the hydraulic cylinder is not used for a long time, please
keep some hydraulic oil inside the cylinder
3. Please use anti-wear hydraulic oil for hydraulic oil
4. Please change the hydraulic oil regularly
6. The bottom of the hydraulic jack must be placed on a level place
before it can be used
7. Do not use hydraulic jacks for partial load
8. Please take safety precautions when using hydraulic jacks
9. We are a complete manufacturer of the system. We not only
manufacture hydraulic cylinders but also provide high-pressure oil
pumps, pressure gauges and various high-pressure valves and
intelligent hydraulic systems
