Schaeffler's Linear Guide Handles 149 Tonne Loads

Schaeffler's Linear Technology division has released the RUE 100 E-L profiled rail linear guidance system that is ideally suited to large production machinery, including high efficiency machine tools and presses. The static load carrying capacity of the unit amounts to 149 tonnes, with dynamic load capacity of 63 tonnes.

The unit provides smooth, uniform running characteristics and high dynamics, suitable for precision linear movement of heavy loads.

Even at these high load carrying capacities, the unit still offers a compact design so that, apart from the required mounting faces, there is no need to take account of any special data for integration in the machine structure.

Machine builders and designers of production machinery can now benefit from a range of linear guides that offer high load ratings, robust design, high rigidity, high precision and excellent sealing.
Speeds of up to 4m/s are possible, as are accelerations of up to 100m/s2.Users can select from a range of accessories to suit their application.

The range also benefits from Schaeffler's injection moulding technology, which enables perfect rolling element guidance in the load and return zones, optimised transitions and the best possible running characteristics with very low stroke pulsation.

Schaeffler has also reduced the number of components in the design, resulting in more robust, reliable rolling element guidance.

Labyrinth seals on the rolling element recirculation system improve protection against contamination.

Uniform lubrication is also guaranteed due to a completely closed and sealed lubrication duct.

The design of the guides also incorporates an efficient sealing concept, comprising standard seals: single lip upper seals, double lip lower sealing strips, as well as double lip end wipers.

The end plates fitted as standard in front of the contact end wipers provide extra protection against coarse contaminants, which means the contact end wipers retain their full performance capability even in environments with fine, often aggressive contaminants.
