Gates® idler brackets are the ideal solution when dealing with drives with a fixed centre distance. Often used when converting fixed centre distance roller chain drives with Poly Chain® GT® Carbon™ belt drives. Belt drives with fixed shafts or limited adjustment, require an alternative way to tension the belts. Gates® idler brackets can be used to tension a belt from the inside or backside using the appropriate attachments (idler sprockets, flat idler pulleys or idler bushings).
