Hydraulic cylinders Ø 100 mm – Power Standard

This category includes double-acting cylinders with a cylinder (piston) inside diameter of 100 mm . This is the boundary size that separates lightweight agricultural hydraulics from heavy-duty industrial solutions. Cylinders of this size combine relatively compact dimensions with powerful usable force.

How much force does the "hundred" actuator have?

This is the most common question from customers. Thanks to its large piston area (78.5 cm²), the 100 mm diameter cylinder generates impressive forces even at standard pressures:

  • At 160 bar: Extension force approx. 12.5 tons .
  • At 200 bar: Extension force approx. 15.7 tons .
  • At 250 bar: Extension force of nearly 20 tons .

Perfect for Splitters and Presses

100mm cylinders are the "gold standard" in strength machine designs:

  1. Log splitters: This is the most common size for building professional auger and hydraulic log splitters. Its 16-20 tons of force easily handles knotty oak or beech.
  2. Workshop presses: An excellent base for building a 20-ton press.
  3. Agriculture: Lifts in large tillage units, feed wagon control systems.
  4. Construction: Spare parts for excavator and loader arms (pay attention to the pin diameter!).

Construction and Durability

The actuators we offer are made in accordance with the art of engineering:

  • Piston rod: Thick rod (typically Ø 50 mm to Ø 70 mm), hardened and chrome-plated for scratch and corrosion resistance.
  • Cylinder: Precision steel tube, honed inside to minimize seal friction.
  • Gland: Bolted, equipped with modern polyurethane (PU) seals and scraper rings, which prevents leaks even during intensive operation.

Models are available with various ends (ear with swivel bearing, sleeve, flange) and with any working stroke (from short 100 mm to long 1000+ mm).

FAQ: Hydraulic Cylinders – Piston Ø 100 mm – Questions and Answers
1. What is the pressure force (lifting capacity) achieved by an actuator with a piston diameter of 100 mm?

100mm cylinders are components for powerful industrial loads. The piston's effective area is approximately 78.5 cm². Depending on the system pressure, they generate enormous forces:

  • At a pressure of 160 bar , the actuator pushes the load with a force of approximately 12.5 tons (12,560 kg).
  • At a standard working pressure of 200 bar , the pressing force is nearly 15.7 tons (approx. 15,700 kg).
  • In advanced systems operating at a pressure of 250 bar , the pressure of this actuator approaches 20 tons (approx. 19,600 kg).
2. Where are such powerful actuators (15-20 tons) used?

The 100 mm diameter is reserved for professional equipment and heavy construction. The most common applications are:

  • Professional Log Splitters: Ideal for building stationary log splitters with a working force of 15-20 tons, capable of handling the most extreme, knotty wood and thick logs.
  • Industrial hydraulic presses: Actuators in press brakes, punch presses and scrap/waste paper crushers.
  • Heavy construction and agricultural machinery: Arms of large excavators, wheel loaders and tipping cylinders on heavy tandem and tridem trailers.
3. How to prevent rod bending under 20 tons of pressure? (Piston rod selection)

The 15-20 ton pressure exerted on an extended rod is an extreme endurance test. Buckling (the rod bending into an arc) is the greatest threat to 100 mm diameter cylinders operating at long strokes.
This class of cylinder uses extremely thick piston rods – typically 50mm to 60mm . If you're building a horizontal splitter or long-stroke press (over 500mm), you absolutely must choose a model with the thickest piston rod available (e.g., 60mm) to ensure safe operation.
4. Why is my 100mm ram extending very slowly?

This is the most common design flaw. A cylinder with an internal diameter of 100 mm has a huge capacity – it requires a huge amount of oil to fill.

  • If you connect this actuator to a small pump (e.g. 20-30 l/min), it will advance at a "snail's pace".
  • To obtain a satisfactory feed speed (which is crucial, for example, in splitting machines to maintain work efficiency), you must use a pump with a flow rate of at least 60 to 100 l/min and an appropriately sized distributor (e.g. 80 l/min or a CETOP 05/CETOP 07 valve).
5. How to safely attach a cylinder with a lifting capacity of 20 tons?

Traditional mountings in such applications would immediately break. Our 100 mm diameter cylinders feature massive lugs with pressed-in pivot bearings mounted on thick pins (most commonly Ø 40 mm, Ø 45 mm, or Ø 50 mm). These bearings allow for minimal movement and compensate for stresses in the machine frame, protecting the cylinder from seizing and lug breakage under maximum load.
