The latest range of Stabilus gas springs and dampers from SKF has been developed to help engineers to design safe, reliable and cost-effective systems for lifting bonnets, hatches, windows and seats.
Stabilus gas springs and dampers are constructed for use in the most demanding applications, making them suitable for use in construction, agricultural and forestry machines.
They are available in a choice of configurations and incorporate a number of features to improve vehicle function and operation, according to the company.
The latest Stabilus Lift-O-Mat hydro-pneumatic gas springs are designed for use in high-load applications, where large panels such as bonnets, access covers and tailgates need to be lifted or lowered in a carefully controlled manner.
The Lift-O-Mat system offers dynamic extension damping, providing a gradual reduction in operating speed at either end of the stroke, in order to reduce shock and wear on hinges or panel joints.
This is achieved either by the use of a gas-filled pressure tube with a longitudinally grooved piston, for medium-weight duties, or, for heavier-duty applications, the use of hydraulic extension dampening.
The latter combines gas- and oil-filled internal chambers with a patented labyrinth design of piston, enabling the degree of dampening to be automatically adapted as the piston moves from the gas to the oil phase.
Also in the latest range are Stab-O-Shoc hydraulic dampers, designed to provide effective motion and vibration dampening and control, for example for operator seats, trailer couplings and V-belt tensioners.
Available in a number of configurations, for vertical or horizontal mounting, Stab-O-Shoc provides instant dampening, with the option of symmetrical force distribution under tension and compression, or the ability to set tension and compression forces independently.
Other products in the Stabilus range include the Hydro-Lift gas spring, which is similar to Lift-O-Mat but with a valve incorporated into the spring unit.
This eliminates the need for additional stop mechanisms, enabling the unit to be locked safely in the compression position, even under conditions of varying load.
Similarly, the Elektro-Lift gas spring is claimed to provide excellent lift control, with the additional feature of an integrated sliding switch to allow it to transfer 12V/25A currents to bonnets or boot lids, providing connection for lighting, heating or windscreen wipers.
All products are manufactured in compliance with DIN EN ISO 9001 and ISO/TS 16949 and are fully supported by the SKF and Stabilus sales and technical teams.
