Product Details


Track rollers for Vee bars/Plain rollers - type FR

The backlash setting and the pre-tensioning of the rollers takes place via the eccentric hub of the rollers of the series FR 
The FR..Z series are the concentric models. In the eccentric rollers, the inner bolts are provided with two holes. These allow for the adjustment of the backlash. If a roller is located in its zero position, the teeth backlash will be the standard value of 0.05 mm flank clearance. 
The service life of the system will be reduced by excessive tensioning. With too little tension the rollers will not run, or will wear due to the poor meshing.
