BELT TIGHTENER - PTGT


Plastic pulleys for V-belts with V-groove: optimal grip and efficient transmission.
Stagnoli’s PTGT series plastic V-belt pulleys are co-molded components that integrate glass-fibre reinforced PA6 technopolymer and a 100Cr6 steel bearing. The V-groove pulley guarantees precise seating of the V-belt, ensuring optimal grip and efficient power transmission without operational slippage.
These components completely eliminate the need for lubrication, reducing maintenance interventions and contamination in production lines. The V-groove pulleys in our catalogue offer superior resistance to dust, moisture and mechanical vibrations, making them ideal for agriculture, industrial machines, compressors and all systems where continuous operational reliability is a critical requirement.
The lightness of the technopolymer reduces stress on supports and extends the life of the entire transmission system. The co-molded bearing ensures smooth rotation and significant noise reduction compared to traditional metal solutions. The precision of the molded V-groove guarantees perfect belt centring and stable tensioning even under demanding operating conditions.
Our expertise in the processing of advanced technopolymers enables us to develop components that effectively combine high mechanical performance with the operational advantages of plastic materials.
