Gates PowerGrip GT3 Pulleys
Gates PowerGrip GT3 pulleys are a best-in-class choice for precision pulleys thanks to the GT3 tooth profile that delivers high power density, low backlash and consistent timing under load. Compared with the German-made BRECOflex pulleys that push absolute positional accuracy, Gates wins on broad availability, standardized sizing and lower lifecycle replacement costs for high-volume applications.

TB Wood's Variable Pitch V-Belt Pulleys
TB Wood's variable pitch V-belt pulleys provide flexible, maintenance-light speed adjustment for precision pulley applications where continuous or fine speed tuning is required, eliminating the need for gearboxes in many designs. They trade the absolute tooth-to-tooth positional repeatability of timing pulleys (e.g., Gates or BRECOflex) for economic and operational versatility, offering strong capex savings in systems that benefit from on‑the‑fly ratio changes.
