Body
The body of the belt is made with thermoplastic polyurethane 92 ShA.
Overview
MEGALINEAR QST
Megadyne offers a range of synchronous polyurethane products that includes MEGALINEAR Quiet Self Track (QST).
The precise and continuous engagement between belt and pulley enables a reduction in noise levels compared with traditional trapezoidal and curvilinear tooth profiles.
In addition, MEGALINEAR QST belts are self-tracking, removing the need for flanged pulleys.
Features
The Offset Tooth design allows MEGALINEAR QST to run more quietly than any other synchronous product. MEGALINEAR QST shows a significant reduction of dB (A) in the applications where traditional timing belt tooth profiles are used.
MEGALINEAR QST design consists of left and right Offset Teeth which guides the belt into the centre of the QST pulley, eliminating any belt wander and ensuring high precision linear positioning. The self-tracking nature of the offset teeth eliminates the need for pulley flanges.
