Roller bearing guideway assemblies
The roller bearing guideway is one of the profile rail guides and is the most viable option. It comes into use when extraordinary longitudinal loads have to be taken and also a high rigidity has to be ensured, whilst at the same time not compromising the accuracy of guidance. They usually come as a full complement variant. The roller monorail is also available with a chain guide. These run much quieter than the full complement version. Despite having less rolling elements a similar load capacity and stiffness value is achieved.
