Gas springs and oil dampers
Eckold reports that it keeps a wide range of standard stroke compression springs in stock which are valved so that the force can be adjusted when mounting on the application if necessary. Various different types of screw-on end fittings and mounting brackets are also available off the shelf. And the latest innovation in the oil damping programme is an adjustable version, which makes life easier if the damping force is uncertain.
Gas Springs are used in a variety of applications, such as guarding of machinery used in the food packaging, brewery and woodworking machinery industries. The design is such that gas springs can overcome the deadweight of a guard, lid or access hatch. Dependent on the force and fixing positions of the spring or springs, a hatch or guard can open immediately after release of a locking catch and remain in the open position. Closing is also made easier as after the initial hand movement, the gas springs will assist in closing.
Gas springs can operate in temperatures from -25degC to +80degC and if fitted correctly have a guarantee of 12 months and more. Various measures of oil are included to give a smooth movement and end of stroke damping. Gas Springs are generally supplied with a chrome piston rod and black spray coated cylinder, but they are also available in complete or partial stainless steel in two grades (304) and (316).
Traction (tension) type gas springs can also be supplied, as well as adjustable locking models in both rigid or elastic locking form for such applications as office seating/desks, computer monitor movement, hospital beds and physiotherapy tables. They are also widely used in marine applications.
