For engineers familiar with the traditional wound spring format, Abssac is offering a new way of looking at reliability, performance and attachment by use of a machined spring.

Abssac is claiming great success with its Heli-Cal machined spring product in the oil and gas industry, where it is used in a variety of applications to store energy, deliver a constant force, measure accurately for deflection or act as a fail-safe device.

Abssac was recently called upon to retro-fit a spring in a fuel control system. The spring unit should compress and extend 2mm but deliver an accurate spring rate over a set life time.

Precision offset couplings are being specially configured for applications in the vacuum industry. A good example is the Semiflex range from Abssac, which has been specified for duties in the field of glass coating technology.

A challenge Abssac faced recently was to develop a flexible shaft coupling that could be used in the drive assembly of an 'aerator' used to oxygenate water in fish spawning ponds and small lakes. Aeration is especially required in times of hot weather where the oxygen concentration within the water can fall and have a detrimental effect on spawning.

Cold rolled formed lead screws are proving to be economical for linear applications requiring repeatable accuracy and reliability. Using a comprehensive range of screw diameters from 3mm through to 24mm, Abssac can match performance and function with its ability to supply custom thread forms. Then, using the latest machining techniques, associated anti-backlash or standard nuts designs can be supplied to any size and shape.
