Cylinder Mounting Frame: Load Capacity 10-500 kN

Component Specifications

Definition

The Cylinder Mounting Frame is a precision-engineered structural component that provides stable, vibration-resistant mounting for cylinders in thrust applications. It ensures proper alignment between the cylinder and the driven load, maintains geometric stability under dynamic forces, and distributes reaction forces to the machine base. Critical for maintaining thrust accuracy and preventing premature cylinder wear.

Working Principle

Functions as a rigid interface that transfers cylinder thrust forces to the machine structure while maintaining precise alignment. It absorbs reaction forces, prevents misalignment from thermal expansion or operational loads, and provides mounting points for cylinder attachment hardware.

Materials

Typically fabricated from structural steel (ASTM A36 or equivalent), stainless steel (304/316) for corrosive environments, or aluminum alloy (6061-T6) for weight-sensitive applications. May include hardened steel bushings or wear plates at mounting points.

Frequently Asked Questions

What is the primary function of a cylinder mounting frame?

To provide rigid, precise mounting that maintains cylinder alignment under operational loads and distributes reaction forces to prevent machine damage.

How does mounting frame stiffness affect thrust system performance?

Insufficient stiffness causes deflection under load, leading to misalignment, reduced thrust accuracy, accelerated cylinder seal wear, and potential rod bending failures.

Can mounting frames be customized for different cylinder sizes?

Yes, they are typically custom-engineered based on cylinder dimensions, load requirements, and machine interface specifications.
