Fescolo Custom Large-Bore Pneumatic Cylinder Solutions
Explore our approach to large-bore cylinder projects, from understanding operating conditions and reviewing the design to machining, assembly and functional testing.
A large-bore cylinder must deliver the required force while fitting the equipment’s mechanical structure and pneumatic system.
Fescolo reviews the complete application before recommending a configuration:
• Force and pressure: Required pushing and pulling force, available operating pressure and load conditions.
• Stroke and movement: Travel distance, movement direction, operating speed and cycle frequency.
• Rod and mounting: Piston rod dimensions, mounting geometry, alignment and external guidance.
• Air supply: Available airflow, connection sizes and valve arrangement.
• Operating environment: Temperature, dust, moisture, outdoor exposure and maintenance access.
These requirements guide the cylindes's dimensions, structure and component selection.
Whether you are developing new equipment or replacing an existing cylinder, we can review the following configuration options.
Design Area | Options for Project Review |
Bore and stroke | Dimensions selected around required force, travel and installation space |
Cylinder construction | Barrel, end-cap and fastening arrangements suited to the operating requirements |
Piston rod | Rod diameter, material, surface finish and connection details |
Mounting | Flange, foot, pivot or application-specific mounting interfaces |
Rod-end connection | Threaded connections, clevises and custom connection dimensions |
Air ports | Connection size, thread type, position and orientation |
Sealing and lubrication | Configurations evaluated for temperature, duty cycle and operating conditions |
Surface protection | Materials and finishes evaluated for the specified environment |
Cushioning and sensing | End-of-stroke cushioning and position-detection options where suitable |
The final configuration, operating limits and acceptance requirements are defined during engineering review and drawing approval.
Cylinder sizing starts with the force required by the mechanism and the pressure available during operation. We review both extension and retraction requirements, together with load variations and the intended movement.
Stroke length, mounting geometry and load direction affect the piston rod and its supporting structure. We review these factors alongside equipment alignment and external guidance requirements.
Large-bore cylinders require a suitable air supply to achieve the intended movement. Port sizes, valves, tubing and exhaust arrangements should be considered together with the required speed and cycle frequency.
Seal selection, lubrication and component protection are evaluated against the actual operating environment. Temperature exposure, dust, moisture and outdoor conditions should be specified early in the project.
Fescolo evaluates large-bore pneumatic cylinders for mechanisms requiring substantial linear force in industrial equipment.
Application Area | Typical Mechanisms |
Mining and bulk material handling | Hopper gates, chute gates and material-diverting mechanisms |
Coal handling systems | Material gates, discharge doors and associated opening and closing mechanisms |
Steelmaking and industrial dust collection | Dampers, isolation gates and equipment linkages |
Heavy industrial machinery | Large equipment doors, pushing mechanisms, clamping and positioning assemblies |
Industrial lifting and tilting | Mechanisms evaluated with suitable guidance and load-holding arrangements |
Suitability depends on the mechanism, load, available air supply and operating conditions. Applications involving suspended loads require appropriate independent safeguards and system-level validation.
Our manufacturing process follows the approved project drawings and technical requirements.
Cylinder barrels, piston rods, pistons, end caps and mounting components are manufactured to the specified dimensions and configuration.
Assembly brings together the sealing, guiding and fastening components according to the approved design, with attention to cleanliness, alignment and lubrication.
The inspection plan is defined around the project requirements. It can include critical dimensional checks, leakage checks, stroke verification and extension and retraction testing.
Where additional pressure, load or endurance testing is required, the test conditions and acceptance criteria are agreed during project review.
We support projects from initial evaluation through sample development and subsequent production.
1. Share your requirements
Send a drawing, existing cylinder specification, photographs or a description of the equipment and its operating conditions.
2. Review the application
Our engineering team evaluates the proposed configuration and identifies technical details requiring confirmation.
3. Approve the drawing
Key dimensions, connections, operating requirements and inspection criteria are confirmed before manufacturing.
4. Manufacture and verify
The cylinder is manufactured, assembled and checked against the agreed requirements.
5. Support subsequent orders
Confirmed drawings and specifications provide the basis for repeat production and future configuration changes.
Prototype quantities can start from one piece, subject to project evaluation. Lead times are confirmed according to the design, materials, quantity and testing requirements.
What bore sizes and stroke lengths can you provide?
Please share your required dimensions or force and travel requirements. We will review a suitable configuration based on the cylinder structure, operating pressure, installation and manufacturing requirements.
Can you work from an existing drawing or cylinder?
Yes. We can review drawings, specifications, photographs and available measurements. Replacement projects also require confirmation of mounting dimensions, connections, operating conditions and any problems with the existing cylinder.
Can you help if we do not have a complete drawing?
Yes. Start with the required force, available pressure, stroke, mounting space and operating conditions. These details help us assess the project and identify the information needed for design development.
Can the cylinder be adapted for dusty or outdoor environments?
We can evaluate sealing arrangements, component materials and surface protection against the specified environment. Please include temperature, moisture, dust and corrosion exposure in your enquiry.
Can we order a prototype before committing to production?
Yes. Prototype quantities can start from one piece, subject to project evaluation. Sample pricing, lead time and validation requirements are confirmed for the individual project.
Tell us what your equipment needs to do.
Share any available drawings, cylinder photographs, required force, operating pressure, stroke, mounting dimensions and expected quantities. Our engineering team will review your enquiry and provide initial technical feedback within 1–2 working days.
