The Ewellix roller profile rail guides LLU are ideal for industries like machine tools, automation, plastic injection molding or material handling. Roller profile rails can provide maximum precision, rigidity, dynamic and static load ratings and smooth-running behavior within a compact design. Carriages (blocks) are interchangeable on a specific rail in standard precision classes. The LLU range is available in four precision classes and two preload classes.
The rigidity is one of the most important criteria in product sélection of LLU roller profile rail guides. Rigidity is defined as the deformation characteristics of a guidance System under extemal load. The rigidity of a System dépends on the magnitude and direction of the extemal load, the type of guidance System (size, carriage type, preload) and the mechanical properties of adjacent support structure.
Following diagrams provide the behavior for each LLU carriage type in vertical tension and compression direction depending on their preload classes T2 andT3. Derived from the real application, the known extemal load with its orientation is to be put on horizontal axis “Load (kN)”. Thus the amount of deflection can be easily read from the vertical coordinate “Deflection (pm)”.
