Some know them from the drawers of their kitchen units, the pull-outs in the oven or steamer, others are amazed when a patient bed is seemingly effortlessly pushed out of an ambulance or a heavy-duty pull-out with rescue equipment is extended and securely positioned on a fire truck. Here as well as there, integrated, ball-bearing rail systems, so-called telescopic or heavy-duty pull-outs, ensure as simple and safe handling as possible.

Ball guides, linear guides, telescopic rails – all of these basically refer to ball-bearing extension rails: they move something forward and backward, they move something up and down, they bring something into the desired position, they enable access to something.

The specialist for this area of "Access Solutions" is Bossard Germany, which not only offers comprehensive solutions with the premium products from Accuride but also has Alexander Dobler among its team, an acknowledged expert in the field.

Custom solutions for tailored requirements

The Senior Expert Engineering Professional states: "There is almost nothing in the Bossard range that we do not have; so far, we have found or developed a tailored solution for every individual customer requirement." With Accuride, a partner is at their side, which has been producing extension rails since the early 1960s and today offers highly complex rails with multiple components and in a variety of materials. The claim and promise: comprehensively tested products with a long service life that meet the highest standards.

The rail systems in various designs "are available in three weight classes," explains Alexander Dobler: "For light loads up to 50 kilograms, for medium loads up to 99, and for heavy loads up to 980 kilograms." The rail can be either a partial or full extension, with the movable element extending beyond the length of the fixed rail element – in contrast to linear guides, where the movable element remains within the fixed element.

Damper-assisted self-closing, latching and locking in both extended and retracted positions, touch release, extension in both directions, sliding guide (for sliding doors), and much more: the variety of conditions and requirements "determines the breadth of Bossard's offerings and their numerous possibilities in various combinations," emphasizes the Senior Expert Engineering Professional: "Our innovative slide systems are available in aluminum or stainless steel, with surfaces that are galvanized, painted white, passivated black, or corrosion-resistant. For very harsh and sterile environments (cleanrooms), grease-free stainless steel rails that withstand temperatures from -80°C to +500°C and are resistant to cleaning with water and cleaning agents are ideal."

Important for installation are adjustment lugs for easy assembly and a front quick-release, through which the inner rail can be separated from the outer rail. In addition to the necessary accessories such as mounting brackets, Bossard also offers an understandable compilation of information and recommendations for the proper selection of the rail in relation to the environmental conditions.
