KALLER gas springs uses compressed nitrogen gas, contained in a cylinder and compressed by a piston rod, to exert a force.
The benefits of gas springs, compared to typical mechanical springs, are:
- ability to create higher force in less space
- immediate presence of force when stroked
- low force increase over the stroke
- easy to adjust the force by increasing or decreasing the amount of gas in the spring.
With the KALLER Force and Temperature Calculator you will be able to determine force profile and operating temperature of the gas springs, even before finishing the tool design.
KALLER gas springs are designed to meet customer expectations for reliability, safety and service life mainly in sheet metal forming applications. But they are capable to handle numerous other applications where high force or energy storage efficiency is required. The design, manufacturing and testing of KALLER gas springs has been approved according to the European Pressure Equipment Directive (2014/68/EU).
