Frequently Asked Questions:

Q. What are pneumatic toggle clamps?

A. Pneumatic toggle clamps feature the same basic design and operation as manual hold down or straight line toggle clamps, but are operated pneumatically. They are completely self contained and require only a pressure source hook up.

Q. How do you adjust a toggle clamp?

A. After clamping, the force can be adjusted by loosening / tightening the spindle nut.

Q. How to specify the right toggle clamp for a particular application?

A. The most important consideration is the size of the component that you're clamping, the amount of space available in the production process and what kind of access you need to have around the clamp. If you are clamping a very small component and you need to hold it close to the clamp, clearly a small clamp will be required. Secondly, one needs to consider the distance between the pivot point and the length of the clamp arm and the weight of the tooling. In addition, the user must also consider the amount of clamping force or holding force you need the clamp to apply.

Q. Is it right to check the specifications?

A. By checking the specifications, you can ascertain the toggle clamp capacity, so it is a firm yes. The product specifications from the manufacturer consist of enough information about the throat depth and jaw opening. You can also ask our dedicated procurement team for an accurate guide.

Q. What does the clamp's holding capacity mean ?

A. The holding capacity or holding force is basically the capability of a clamp to hold down mechanical equipment or sheet metal while assembling automotive parts or during manufacturing processes.

Q. What does clamping force mean?

A. Clamping force is the amount of force actually applied to the workpiece by closing & locking the clamp. It is normally less than the stated holding capacity. The actual clamping force depends on various factors, including cylinder bore, cylinder area, spindle position (clamping arm length) and available air pressure. In most cases, the clamping force is approximately 2 to 3 times the force exerted by a pneumatic cylinder.
