Attentions In Type Selection of Hydraulic Cylinder

Lifting Force Solutions

Always choose a cylinder with extra 20% ~ 30% more capacity than required.

Please use cylinders with sufficient lifting margin when combined to use several Hydraulic Cylinder, which may possibly cause uneven load .

Stroke Solutions

Please use cylinders with sufficient stroke margin.

Return-stroke Function

Single Acting

Spring return: Piston rod retracts by built-in spring. When this kind of cylinder is used horizontally or the front end of the piston rod is provided with an accessory part, it will result in difficult return or no return.

Load (external force) return: No spring. To get the piston rod return back, there must be “external force”.

Return speedsof above two returnways may be not same . No pulling force, the two types of cylinders can not be used to pull load.

Double Acting

Hydraulic return: chosen when pulling force is necessary. Faster return can be achieved by hydraulic.

Used when reverse, horizontal use or front end of piston rod is provided with a subsidiary part.

Pullingforceis about 1/2the lifting force. Please confirm with the specification sheet.

Working Speed Range

Capacity of cylinder and flow of pump station is different, the speed of cylinder is also different.

Please consult our sales engineer about specific speed.

Use Frequency

Please choose the RC or RR Series when the frequency of use is high.

Use Environment

Please use when ambient temperature is within -20℃ ~ +40℃.

Cylinder sealing ring used when ambient temperature is within -25℃ ~ +80℃.

Allowable Transverse Load

When cylinder takes all the load, please noted that don’t add oblique load and impact load, allowed transverse load (Don’t exceed 5% lifting load.).

Lifting Direction

Cylinder can be used "vertically, horizontally, obliquely, reversely", but must add load to the piston rod vertically.
