The classical timing belt (synchronous) has a trapezoidal tooth profile providing a positive drive by the meshing of belt teeth with the grooves of a relating timing belt pulley. It has a wide range of applications from typewriters to heavy industrial machinery.

Construction and Features
The glass fibre tensile member provides high strength to transmit tensile forces and withstand shock loads with
virtually no stretch. The abrasive resistant cover protects the teeth when in contact with the pulley and helps to reduce noise.
The meshing of the teeth prevents belt slip and speed variations, thus ensuring perfect synchronisation and positive

Conform to 1S05296, they meet 1S01813 for static conductivity and have an operating temperature range of -25°C - +100°C.
