Custom Trunnion-Mounted Long-Stroke Hydraulic Cylinder with Stop Tubes
This APEX-CMDC trunnion-mounted hydraulic cylinder is optimized for heavy industrial presses and equipment requiring long strokes and high stability. With a bore range of 50–320 mm and working pressure up to 250 bar, it delivers substantial force for pressing and forming operations. The optional stop tubes increase bearing area, enhancing stability on long-stroke applications. Double-acting design with single or double rod configuration. Trunnion mounting allows for pivoting motion, suitable for applications where the cylinder needs to articulate. Designed for frequent cycling and high load, with replaceable gland for easier maintenance.
Key Selling Points
Stop tubes option enhances long-stroke stability by increasing bearing area, reducing bend and deflection.
Trunnion mounting (head, cap, or intermediate) allows pivoting motion, accommodating misalignment and dynamic loads.
Designed for frequent cycling and high load, making it suitable for continuous industrial presses.
Large bearing areas provide smooth operation under high side loads.
Optional adjustable cushioning controls high-inertia loads near stroke end, improving safety and longevity.
Heavy-duty roundline construction ensures structural rigidity for demanding applications.

FAQ
Q1: What is the advantage of stop tubes?
Stop tubes increase the bearing area between piston and barrel, reducing deflection and wear on long-stroke cylinders.
Q2: Can trunnion mounting accommodate angular movement?
Yes, trunnion mounting allows the cylinder to pivot, suitable for applications where alignment changes.
Q3: What is the maximum stroke length?
Up to 3000 mm standard; longer strokes require individual engineering review.
Q4: Can the cylinder be used in high-frequency cycling?
Yes, it is designed for frequent, repeated cycling in heavy industrial applications.
Q5: Are position sensors available?
Yes, proximity switches, linear position sensors, or continuous transducers can be integrated.
