While it seems logical, it isn’t always the case. Sometimes the combination of the belt and the system requires two, small v-guides the will steer the belt andtstill flex around the pulleys (versus one larger v-guide that would have difficulty flexing around the pulleys). However, if the v-guides are not placed on the belting with extreme care, you could end up with a situation where the two v-guides are actually working against each other. This can cause premature failure of the v-guides and can cause the guides to lift out of the grooves they are intended to ride in.We recommend that the v-guide be applied to the center line of the base belt; however, in unusual circumstances, it can be fused off-center. We do NOT recommend the use of more than one v-guide on the pulley surface for tracking purposes. Also, v-guides are meant only to improve tracking…not to drive the belt. Grooves required in pulleys and slider beds to accommodate v-guides must be manufactured both 1/4 inch wider and 1/16 inch deeper than the v-guide size selected to allow for sufficient “play”.
