GR type linear system bearings could utilize either cross roller or ball as rolling elements.The two will differ substantially in load ratings.The ratio is approximately 10 to 1 in favor of rollers, depending upon the dimention under consideration. Balls are more advantageous in case of presence of impurities and/or misalignment as it happens when the structure, to which rails are anchored, is ...

This rail type completes the system RM/RV.The RVA has the raceways coated with antifriction material. This type is used when the speed is relatively low (20 m/min max) and the rigidity of the system is critical.A set is composed of two rails RM ant two rails RVA. The rails RVA and RV are dimensionally interchangeable. In order to have a good functioning, the temperature of working must be ...

The present evolution of the GR type is passing through the realization of guideways that in spite of their smaller section are performing better features in respect of the carrying capacity and therefore of stiffness. This new kind of guideway named NG has two different sections whose dimensions are stated in the following ...

The rails type “GRD” have been designed to semplify assemblies and to increase structural rigidity. They can be used with the table TR and TRL upper portion to increase the economical benefits. They are an integral component of recirculating systems ...

The same calculation criteria used for GR rails is valid for the rails RM/RV. However, the different with grtype, should be accounted for: 1) Higher load ratings; 2) Higher rigidity; 3) Better overlapping of the rollers, especially in case of short stroke; 4) Higher sensibility to mounting errors and ...
