Double-tube linear axles with new size
Linear axes for special machine construction at Motek 2023
RK Rose+Krieger is presenting new linear technology solutions at its stand 3203 in hall 3 at Motek in Stuttgart. With the double-tube units of the EP(X)-II series, the manufacturer offers precise positioning modules for medium to high loads in any installation position. Following on from sizes 30 and 40, another popular axis size, size 50, has now been added to the RK portfolio.
Like the other models in the series, the new size 50 with trapezoidal spindle and an overall length of up to three meters compensates for high bending moments during manual and motor adjustment. Further advantages of the robust linear axes are their ease of maintenance and the fact that they are easy to clean. The concept of the split guide nut contributes to the ease of maintenance: This can be easily replaced in the event of wear without having to dismantle the linear axis.
Linear units with trapezoidal screw drive or ball screw drive
The double-tube units impress with their good running properties, high rigidity and freedom from play of the guide carriage over the entire stroke. Modern materials and the standard use of high-performance slideways ensure the good running properties, low wear and therefore long service life of the EP(X)-II linear units. Both double-tube axes with trapezoidal screw drive from the EP(X)-II series and double solid shaft versions with precise ball screw drive from the EPX-II KG series are available - the former are more suitable for occasional movement, the latter also for dynamic movement. Users can combine the compatible standard solutions as required. Which linear units are used depends on the requirements of the respective application.
Compatible with previous models
Linear units of the EP(X)-II series are compatible with the previous popular EP(X) units in all functional dimensions, external dimensions and spindle pitches. This means that applications in which the older models are used can be optimized with the new models without any design effort. It is not necessary to replace accessories such as handwheels or position indicators.
Various versions available
The twin-tube units are optionally available in "right and left-hand thread", "right or left-hand thread" or split threaded spindle versions. A manual, force-locking spindle clamp is available as an option. It ensures secure locking of the guide carriage and thus prevents unintentional movement of the carriage.
