Cross roller assemblies for precision rail guides are widely used in the industry because of the high load-carrying capacity, rigidity and precision. In addition to the standard LWR range, Ewellix offers a high-performance range LWRE with a five times higher load carrying capacity and twice as high rigidity. The improved performance of the LWRE range is the result of larger roller diameters with optimised inner geometry at the same outer dimension.
Benefits:
- Highest possible toughness and rigidity
- Applicable for higher temperature applications
- Suitable for high dynamic motions
Features:
- Cross rollers in standard and high-capacity version
- Modular with ranges at same outer dimensions
- High acceleration with anti-creeping system
