العربية5 Ton Hydraulic Cylinder
A 5 ton hydraulic cylinder needs a bore of at least Ø62.5 mm at 160 bar; the nearest standard FDH bore is Ø63 mm, which delivers 5.1 metric tonnes (5.6 US tons). At the optional 250 bar, Ø50 mm is enough (5.0 t). The bore follows from F = p × A.
Fenitsa builds FDH series and special-bore hydraulic cylinders (rams) in this class as double acting units with flange, foot or clevis mountings; check your own load with the force calculator.
Bore Required for 5 Tons
Required bore D = √(4F / πp). The standard bore is the next larger FDH catalogue size.
| Pressure | Required bore | Standard FDH bore | Force of that bore |
|---|---|---|---|
| 100 bar | Ø79.0 mm | Ø80 mm | 5.1 t |
| 160 bar | Ø62.5 mm | Ø63 mm | 5.1 t |
| 250 bar | Ø50.0 mm | Ø50 mm | 5.0 t |
Push and Pull Force of Nearby Standard Bores
| Bore / rod | Push 160 bar | Push 250 bar | Pull 160 bar |
|---|---|---|---|
| Ø50 / Ø28 | 3.2 t | 5.0 t | 2.2 t |
| Ø63 / Ø36 | 5.1 t | 7.9 t | 3.4 t |
| Ø80 / Ø45 | 8.2 t | 12.8 t | 5.6 t |
Buckling: Maximum Free Length by Rod Diameter
Euler buckling with a steel rod (E = 210,000 N/mm²) and a safety factor of 3.5; the value is the buckling length Lk between two pivoted ends.
| Rod diameter | Force (160 bar) | Max. buckling length Lk |
|---|---|---|
| Ø36 mm | 49.9 kN | 980 mm |
| Ø45 mm | 49.9 kN | 1,540 mm |
Speed and Pump Flow
| Extend speed | Required flow | Hydraulic power (160 bar) |
|---|---|---|
| 25 mm/s | 4.7 L/min | 1.2 kW |
| 50 mm/s | 9.4 L/min | 2.5 kW |
| 100 mm/s | 18.7 L/min | 5.0 kW |
Where Is a 5 Ton Hydraulic Cylinder Used?
- Typical machines: hand-operated presses, lifting tables, welding fixtures, small tipping trailers
Workshop presses, clamping fixtures, lifting tables and light forming work sit in this class. The small bore keeps the cylinder compact and a low-flow power unit is enough.
Worked example: for 5 t, a 300 mm stroke and a 10 L/min pump, a Ø63 mm cylinder extends at about 53.5 mm/s, finishes the stroke in 5.6 s and moves 0.94 litres of oil per stroke.
Frequently Asked Questions
What bore do I need for a 5 ton hydraulic cylinder?
At least Ø62.5 mm at 160 bar; the standard choice is Ø63 mm, which gives 5.1 t. At 250 bar, Ø50 mm is enough (5.0 t).
Does 250 bar allow a smaller bore?
Yes. Force is proportional to pressure, so 250 bar gives about 56 % more force than 160 bar from the same bore. The cylinder, hoses and pump must all be rated for 250 bar. 5 t: Ø63 mm @160 bar → Ø50 mm @250 bar.
Does the stroke change the force?
No, but it changes buckling. On a Ø63 mm cylinder with a Ø36 mm rod the maximum buckling length is about 980 mm; a longer stroke needs a thicker rod or guidance.
What pump flow is needed?
About 9.4 L/min moves a Ø63 mm cylinder at 50 mm/s. More flow means more speed; it does not change the force.
