New dimensions for linear guides and multi-axis systems

RK Rose+Krieger has added a more compact size to its successful RK Monoline MT linear unit range. The RK Monoline MT 60 opens up tight installation spaces while maintaining the same high load-bearing capacity. This allows linear axes and multi-axis systems to be dimensioned more precisely.

While the linear units of the RK Monoline MT series were previously limited to size 80, the RK Rose+Krieger modular system now also offers the linear axes in size 60. This is suitable for all applications that require linear guides with more compact dimensions or where an RK Monoline MT 80 is oversized. The dynamic load limit of size 60 is 100 kg (1,000 N) in the axial direction; strokes of up to 5.5 meters are possible.

RK Monoline MT 60 offers proven performance advantages

Machine and system manufacturers also benefit from the advantages of the linear unit series in the more compact size. The roller guide components have an omega-shaped toothed belt drive. This means that the toothed belt does not run around, but is fixed to the end plate on both sides. The drive is located on the carriage and can be mounted variably on two sides. This principle means that the axis can be fitted with several carriages. The linear axes of the RK Monoline MT series allow high travel speeds of up to 5 m/s with a maximum acceleration of 15 m/s². Thanks to their smooth running behavior, they achieve a repeat accuracy of ±0.05 mm. They are easy to maintain as they can be lubricated centrally via the carriage.

RK multi-axis modular system gets more customization options

RK Rose+Krieger has designed the linear units in the RK Monoline MT series specifically for use in pick & place, palletizing and loading and unloading processes. Thanks to grooves and centering holes as well as system brackets, system plates and clamping strips from the RK multi-axis modular system, they can be quickly and easily assembled into multi-axis systems. With a fixed carriage and moving profile, they can be used as cantilever or horizontal axes, for example for a handling gantry. With the payload on the moving carriage, they can be used as a vertical axis or as a gantry drive with two vertical axes. The customization options of the RK multi-axis modular system have been further increased by the RK Monoline MT 60.

RK Safelock keeps loads where they are

Especially for vertical applications, all sizes of the RK Monoline MT can be equipped with the RK Safelock holding element, which works independently of the motor brake. Spring elements are pressurized with compressed air; when this is switched off, the steel springs securely hold the axle in place. This prevents accidents during assembly, disassembly and maintenance work caused by falling guide carriages. As a self-reinforcing system, the holding force of the system is guaranteed even with greased rails. The nominal holding force is 1,500 N, the maximum holding force is 3,000 N.
