العربيةMini Hydraulic Cylinders: Compact Ø40, Ø50 and Ø63
Mini hydraulic cylinders deliver tonnes of force from a small body. At 160 bar, the smallest FDH bore (Ø40) already pushes about 2 t — more than a Ø200 pneumatic cylinder at 6 bar.
Fenitsa's compact range starts at Ø40 bore with Ø25 or Ø28 rods; the table shows forces for Ø40, Ø50 and Ø63.
Typical Cylinder Functions
- Clamping and fixtures — machine tools and welding jigs.
- Small presses — punching, marking and assembly.
- Mobile equipment — locks, latches and small actuators.
- Automation — where pneumatics cannot give enough force.
Force Table
Fenitsa FDH bores; pull force with the smaller standard rod.
| Bore | Rod | Push 160 bar (t) | Pull 160 bar (t) | Push 250 bar (t) |
|---|---|---|---|---|
| Ø40 | Ø25 | 2.1 | 1.2 | 3.2 |
| Ø50 | Ø28 | 3.2 | 2.2 | 5.0 |
| Ø63 | Ø36 | 5.1 | 3.4 | 7.9 |
Design Requirements
- Short stroke and compact mounting (flange or clevis).
- Small hydraulic power unit or hand pump.
- Rod-end thread M16×1.5 on Ø40, M20×1.5 on Ø50.
- Stroke from 100 mm standard, other lengths on request.
Worked Example
For a push load of 1 t with a 25 % reserve, a Ø40 mm cylinder at 160 bar gives 2.1 t. With a 6 L/min pump it moves at about 80 mm/s and covers a 150 mm stroke in 1.9 s.
Frequently Asked Questions
What is the smallest Fenitsa hydraulic cylinder?
The FDH series starts at Ø40 bore with a Ø25 or Ø28 rod.
Mini hydraulic or pneumatic?
Below about 1.8 t pneumatics may be enough (a Ø200 air cylinder pushes 1,884 kg at 6 bar); above that, a small hydraulic cylinder is far more compact.
Can a mini cylinder run on a hand pump?
Yes, single- and double-acting compact cylinders are often driven by a hand pump for occasional use.
How much force does a Ø50 hydraulic cylinder produce?
At 160 bar a Ø50 mm cylinder pushes 3.2 t. Force = pressure × piston area; the pull force is lower because the rod reduces the area.
