Product catalog summary

Introduction
Steel-Smith Pneumatic Toggle Clamps integrate reliable toggle action with pneumatic actuators, enabling high-speed operations and controlled clamping pressures. These clamps can be operated instantly and arranged in any sequence, offering various models to meet diverse clamping needs. They reduce operator strain, maintain lock during air failure, and cut production time by 40%.

What is a Pneumatic Toggle Clamp?
A Pneumatic Toggle Clamp is a toggle clamp actuated by a double-acting pneumatic cylinder. It includes a cylinder, clamping arm, linkages, and a mounting base. Air pressure moves the clamping arm to secure the workpiece, and the clamp remains locked until air pressure is applied to the unclamping port.

Toggle Principle
The toggle mechanism amplifies the applied load into a high clamping force, creates an over-center lock to prevent accidental opening, and allows rapid opening and closing for easy loading and unloading.

Holding Capacity and Clamping Force
The holding capacity is the maximum force a clamp can withstand without damage. Clamping force is generally less than holding capacity and depends on factors like spindle position, cylinder bore, and air pressure. Using specified clamping arms is recommended to avoid wear and tear.

Types of Pneumatic Clamps

Hold Down Action: Operated pneumatically with a toggle action principle, ensuring lock during air failure. Compact design allows free tool movement.
Fixed Cylinder: Similar to Hold Down Action but with a fixed cylinder, allowing solid tubing use in welding applications.
Right Angle Hold Down: Offers mounting flexibility and is suitable for space-constrained areas.
H.V. Series: Air-powered version of manual H.V. Series with a strong toggle mechanism.
Straight Line Action: Pneumatically actuated with a double-acting cylinder, suitable for fixtures requiring component location.
SSC Series: Designed for precision and compactness, compatible with various pneumatic cylinders, and customizable for mounting.

Model Specifications
Various models are available with different operating pressures, holding capacities, cylinder strokes, and bore sizes. For example, Model AOT - 2535 UB operates at 2-6 Bar with a holding capacity of 100 Kgs and a cylinder stroke of 40mm.

Pneumatic Clamps Introduction What is a PneumaticToggle Clamp? A PneumaticToggle clamp is a basically aToggle Clamp actuated with a double acting pneumatic cylinder. Port for unclamping Toggle linkages The Clamps consists of a double acting cylinder, a clamping arm, linkages for multiplying the applied force, and a base for mounting at the workplace on its base. Air pressure in applied in the clamping port, which thereby moves the clamping arm to hold the work piece.A required clamping force is achieved and exerted on the work piece.Under this action theToggle Clamp Holds the work piece firmly...

Pneumatic Clamps Types of Pneumatic Clamps Hold Down Action - Pneumatic Clamps These clamps utilize the same basic design and operation as manual hold down, only they are operated pneumatically. As the clamp uses the toggle action principle it ensures that the clamp stays locked in the event of air failure. These clamps are extremely compact in design and feature a very low height, allowing free movement of operating tools in drilling, tapping, milling etc.The clamp units are completely self contained with a double acting cylinder and require only to be connected to the air line. The clamping...
