Expansion joints serve a crucial role in industrial ductwork by facilitating the controlled expansion and contraction of ducts. Their primary function is to accommodate thermal movements within the ductwork system. They mitigate thermally induced stresses by allowing thermal movements in a relatively unrestricted manner. Expansion joints contribute to the overall flexibility and structural integrity of the system which is essential in preventing the build-up of stress that could otherwise lead to damage in equipment, ductwork, and supporting structures.

Profile guide rails can be screwed on from above. The profile guide rails are available in four sizes and one or more carriages can be assembled on them. 4row versions with round arch profile. The tracks of the profile guide rails are set below an angle of 45° and thus can carry loads from all directions. The profile guide rails correspond to the market standard and can replace linear guides of the same design by other manufacturers. On request Lengths up to a max. 3960 mm.
