Pneumatic Clevis Mount

1. Technical Definition

A pneumatic clevis mount is a mechanical mounting component used to secure a pneumatic cylinder to a machine structure while allowing pivoting movement during cylinder operation.

The clevis mount typically consists of a U-shaped bracket that attaches to the cylinder end and connects to the machine frame using a clevis pin. This mounting style allows the cylinder to pivot slightly as the piston rod extends and retracts, preventing stress on the cylinder body.

In roll forming machines, pneumatic clevis mounts are commonly used in systems supporting:

Pneumatic punching units
Material clamping systems
Automation positioning cylinders
Air-powered pressing mechanisms
Pneumatic lifting and pushing actuators

They provide flexible mounting for pneumatic actuators.

2. Where It Is Located

The pneumatic clevis mount is installed at the base or rod end of a pneumatic cylinder where it connects to the machine frame.

Common installation locations in roll forming machines include:

Pneumatic actuator mounting points
Punching system cylinders
Clamping actuator systems
Material positioning mechanisms
Automation pneumatic assemblies

The clevis mount connects the cylinder to the machine structure through a pivoting joint.

3. Primary Functions

3.1 Secure the Cylinder to the Machine

Provides a mounting connection between the cylinder and machine frame.

3.2 Allow Pivoting Movement

Permits slight angular movement during piston extension and retraction.

3.3 Reduce Mechanical Stress

Prevents misalignment forces from damaging the cylinder.

3.4 Support Actuator Stability

Maintains proper positioning of the pneumatic cylinder.

4. How It Works

The pneumatic clevis mount allows the cylinder to pivot during operation.

Typical operation process:

The clevis mount is attached to the cylinder end cap or piston rod.

A clevis pin passes through the mount and machine bracket.

The pin forms a pivot joint between the cylinder and machine structure.

As the piston rod extends or retracts, the cylinder can rotate slightly.

This movement accommodates minor alignment changes during operation.

The pivot joint prevents excessive side loading on the cylinder.

5. Types of Pneumatic Clevis Mounts

Rear Clevis Mount

Installed on the rear end cap of the cylinder.

Rod Clevis Mount

Installed on the piston rod end.

Adjustable Clevis Mount

Allows alignment adjustments during installation.

Heavy-Duty Clevis Mount

Designed for high-load pneumatic actuators.

6. Construction & Materials

Pneumatic clevis mounts are manufactured from strong materials designed to support mechanical loads.

Common materials include:

Carbon steel
Stainless steel
Forged steel components
High-strength alloy steel

Important structural characteristics include:

U-shaped mounting bracket
Clevis pin mounting holes
Load-bearing structural design
Corrosion-resistant surface coatings

These features ensure reliable cylinder mounting.

7. Design Considerations

Engineers consider several factors when selecting clevis mounts.

Important considerations include:

Cylinder bore size
Load capacity requirements
Mounting alignment
Pin diameter and strength
Material durability

Proper mount selection ensures safe actuator installation.

8. Load & Stress Conditions

Pneumatic clevis mounts must withstand:

Mechanical loads from cylinder operation
Repeated actuator movement
Machine vibration
Shock loads during operation

Industrial mounts are designed for long service life.

9. High-Speed Production Considerations

High-speed roll forming machines often use pneumatic cylinders that cycle frequently. Clevis mounts must maintain secure attachment while allowing free pivoting movement.

10. Heavy Gauge Applications

Heavy gauge roll forming machines may use reinforced clevis mounts capable of handling higher actuator forces.

11. Light Gauge Applications

Light gauge roll forming machines typically use smaller pneumatic cylinders with lighter clevis mounts.

12. Common Failure Causes

Pneumatic clevis mounts may fail due to:

Excessive side loading
Pin wear or failure
Mechanical fatigue
Improper installation

Routine inspection helps prevent mounting failures.

13. Symptoms of Clevis Mount Issues

Technicians may observe:

Loose cylinder mounting
Excessive cylinder movement
Worn clevis pins
Misalignment during actuator operation

These symptoms may indicate mount wear or damage.

14. Installation Requirements

Proper installation of pneumatic clevis mounts includes:

Aligning the cylinder with the machine mounting bracket
Installing the clevis pin securely
Using retaining clips or locking devices
Checking cylinder movement after installation

Correct installation ensures stable actuator mounting.

15. Maintenance Requirements

Routine maintenance should include:

Inspecting clevis pins for wear
Checking mounting brackets for damage
Ensuring retaining clips remain secure
Lubricating pivot points when required

Regular maintenance ensures reliable cylinder mounting.

16. Typical Replacement Cost

Pneumatic clevis mount costs vary depending on cylinder size and load capacity.

Typical price ranges include:

Small clevis mount
$15 – $50

Industrial clevis mount
$50 – $200

Heavy-duty clevis mount
$200 – $500+

Costs depend on material and load rating.

17. Safety Considerations

A damaged clevis mount may lead to:

Cylinder misalignment
Loose actuator mounting
Unexpected actuator movement
Mechanical failure of the mounting system

Proper mount maintenance ensures safe actuator operation.

18. Role in Roll Forming Machine Assemblies

Pneumatic clevis mounts support pneumatic systems used in roll forming machines including:

Pneumatic punching systems
Air-operated clamping mechanisms
Material positioning systems
Automation control systems
Compressed air actuator systems

They secure pneumatic cylinders to machine structures while allowing pivoting movement.
