Cylinder Clevis | Roll Forming Machine Hydraulic Cylinder Clevis Mount
Cylinder Clevis
1. Technical Definition
A cylinder clevis is a fork-shaped mounting component used to attach a hydraulic cylinder to a machine frame or structural bracket. The clevis provides a pivoting connection that allows the hydraulic cylinder to move slightly during operation while transmitting force to the machine.
The clevis mount typically includes two parallel mounting ears with a hole for a clevis pin, which connects the cylinder to the machine structure. This type of mounting allows angular movement and reduces stress on the hydraulic cylinder during operation.
In roll forming machines, cylinder clevis mounts are commonly used in hydraulic systems powering:
Hydraulic flying cutoff systems
Hydraulic punching units
Hydraulic pressing systems
Hydraulic positioning actuators
Hydraulic lifting mechanisms
They provide a flexible mechanical mounting point for hydraulic cylinders.
2. Where It Is Located
The cylinder clevis is typically installed at the base end or rod end of a hydraulic cylinder.
Common installation locations in roll forming machines include:
Hydraulic cutting system cylinders
Hydraulic punching unit cylinders
Hydraulic press actuators
Hydraulic positioning mechanisms
Hydraulic lifting assemblies
It connects the hydraulic cylinder to the machine frame using a clevis pin.
3. Primary Functions
3.1 Mount the Hydraulic Cylinder
Provides a secure connection between the cylinder and machine structure.
3.2 Allow Pivoting Movement
Permits slight angular movement during cylinder operation.
3.3 Transfer Mechanical Force
Transmits the force generated by the hydraulic cylinder to machine components.
3.4 Reduce Structural Stress
Prevents excessive loading on the piston rod and cylinder body.
4. How It Works
The cylinder clevis forms a pivoting mechanical joint between the hydraulic cylinder and machine structure.
Typical operation process:
The clevis mount is attached to the hydraulic cylinder base or rod end.
Two parallel clevis ears align with a machine mounting bracket.
A clevis pin passes through the aligned holes.
The pin allows the cylinder to pivot slightly during movement.
The hydraulic cylinder pushes or pulls the connected machine component.
Force is transferred through the clevis joint to the machine structure.
This allows controlled mechanical motion while maintaining alignment.
5. Types of Cylinder Clevis Mounts
Base Clevis Mount
Installed at the rear end of the hydraulic cylinder.
Rod Clevis Mount
Installed at the piston rod end of the cylinder.
Adjustable Clevis Mount
Allows adjustment of the mounting position.

Shock loads during hydraulic operation
Mechanical vibration from machine movement
Repeated force cycles
Industrial clevis mounts are designed for long service life.
9. High-Speed Production Considerations
High-speed roll forming machines often require rapid hydraulic cylinder movement. Clevis mounts must maintain stable connections while allowing pivoting movement.
10. Heavy Gauge Applications
Heavy gauge roll forming machines often use large hydraulic cylinders with heavy-duty clevis mounts designed to handle large mechanical loads.
11. Light Gauge Applications
Light gauge roll forming machines typically use smaller hydraulic cylinders with standard clevis mounts.
12. Common Failure Causes
Cylinder clevis mounts may fail due to:
Excessive mechanical loads
Clevis pin wear or damage
Misalignment of machine structures
Metal fatigue or cracking
Routine inspection helps prevent mounting failure.
13. Symptoms of Cylinder Clevis Issues
Technicians may observe:
Excessive movement in the mounting joint
Noise or vibration during operation
Visible cracks or wear on the clevis
Misalignment of hydraulic cylinders
These symptoms may indicate clevis mount problems.
14. Installation Requirements
Proper installation of cylinder clevis mounts includes:
Aligning the clevis ears with the machine bracket
Installing the correct clevis pin
Securing the pin with locking hardware
Ensuring proper cylinder alignment
Correct installation ensures stable hydraulic cylinder operation.
15. Maintenance Requirements
Routine maintenance should include:
Inspecting the clevis mount for cracks or wear
Checking clevis pins for damage
Verifying secure locking of the clevis pin
Lubricating pivot joints when required
Regular maintenance helps maintain reliable mounting performance.
16. Typical Replacement Cost
Cylinder clevis mount costs vary depending on size and design.
