Raw Edge Variable Speed Belts Features
Variable speed V-belts, also termed V / S - belts, are temperature and
oil resistant as well as anti-static. A special rubber compound with
textile fibres oriented across the length of the belt provides high
stability and minimizes deflection in the cross section. The moulded
cog ensures maximum flexibility and optimum fit in the pulley grooves.
The cord, the power transmitting element, has been designed for heavy
power transmission while at the same time ensuring a very high degree
of length stability. Special belts are produced to order, e.g.with
Aramid cord .Construction
