compact rail

In order to obtain the best results with K+Usystem, it’s advisable to utilize NUE.. slidersin the U-rails.All the following data about U-rails refer to thissolution.It’s important to consider that during themovement, while the slider in the K-rail rotates,the slider in the U-rail rotates and offers an axialdisplacement. The combination of thesecorrective movements must not exceed themaximum values listed below.Considering the NUE.. slider competely rotatedat its maximum value (2° for 43 size and 1° for63), the maximum and minimum axialpositioning are identified by the values of B 0maxand B 0min, which already take into considerationthe axial displacement due to the rotation. B 0nomis the suggested value for the “nominal”starting position of NUE.. slider in the U-rail, tobe utilized for the K+U system:The K+U system can be used in differentconfigurations.Considering the same example made in theprevious chapter, this solution, besides toavoid oscillations an consequent overturningmoments, allows to absorb large errors ofvertical parallelism between the rails, withoutcompromising the sliding quality. This is veryimportant because of the difficulties toguarantee good values of vertical parallelism,especially when the distance between the railsis very great.KUCat. 41-41bEA35
