Product Introduction

Single acting hydraulic cylinder only have one oil inlet port to either extend or retract the hydraulic cylinder. In principle, single-acting cylinders have only one effective piston area. Once full stroke is hit the movement to return the cylinder to its start position is usually achieved by using the load lifted, gravity or a spring. An additional port is usually added on the non-oil side of the tube, this allows the hydraulic cylinder to breathe air in and out as it is extended or retracted. Usually this port would be fitted with either a breather or a hose that would connect this area to the hydraulic tank, this is to reduce corrosion issues caused by moist air being drawn in and out of the cylinder tube.

Single acting hydraulic cylinders are mostly equipped with plunger pistons. However, they can also be formed by the single sided application of pressure to a differential piston.

We can production many kinds of single acting cylinder and double acting cylinder. Please send us your requirements. we can customized for you.

1.Rod are chrome plated.
2. Tubes are quenched and tempered.
3. Tube inner hole goes through deep hole boring machine processing. Surface roughness is 0.4Ra and circular degree is 0.025.
4. Good quality yet lower price.

Q3: How can I buy a cylinder from you?
A: Very easy! Just leave me a message or email or call me directly, let me know you are interesting in our products. I will reply you soon and we together talk to confirm details. According to your detail requirements we product samples for you testing.

Q4: Could you quote you the price for the cylinder?

A: 1. Please advice the drawing with your technical requirements.
2. Please advice the model No. if it is a standard hydraulic cylinder.
3. Please advice cylinder tipping capacity, number of stages, closed length, mounting type and size.
4. Please also advice order quantities, this is very important.

Q5: Do your products come with a warranty?
A: Yes, we have 12 months warranty. Under warranty period, if the quality problems we will free repair or replace new one for you.

Q6: Hydraulic cylinder internal leakage?
A: 3 main reasons causing internal leakage: Overload, polishing bad controlled, cheap seal kits.
