Belt Tightener - PTGT
Plastic pulleys for V-belt with V-groove, guarantee optimal grip and silent operation.

Plastic pulleys for V-belt with V-groove, guarantee optimal grip and silent operation.
Plastic pulleys for flat belt with co-molded bearing, ideal for belt drive transmissions and low maintenance.
Plastic pulleys for round belt with single groove and integrated bearing for precise and reliable tensioning.
Stagnoli’s plastic belt tightener pulleys are distinguished by their construction, which combines a polyamide technopolymer (PA6) body reinforced with glass fibre and a co-molded 100Cr6 steel bearing. This technical solution ensures correct belt tensioning, reducing system wear and noise. The absence of lubrication requirements and natural resistance to moisture and external agents make them the ideal choice for sectors such as agriculture and packaging machines. The lightness of the polymer and the smoothness of the bearing combine to offer efficient, low-maintenance transmission.
Thanks to our expertise in the design of hybrid components, we provide belt tightener pulleys that guarantee greater durability and reliability, even in the most demanding industrial applications.
