¡ô materials & usage
V-belt (former name: triangle belt) is a kind of conveyor belt with
isosceles trapeziform as cross section, whose working face is two
side faces. Widely used in the power transmission on machinery and
equipment of electromotor and gas engine drive. The high-quality
V-belt produced by our company takes high power polyester cord as
power layer, whose physical & mechanical capabilities are all
higher than GB£¯T1171¡ª1996 standard, adaptable in the requirement
of large power, high speed, long lifetime and small deformation;
developed standard V-belt in recent years adopts high power polyester
cord as the power layer as well, whose physical & mechanical
capabilities are all higher than GB£¯T1171¡ª1996 standard, with more
resonable capability & price rate, enlarging the using scope
of V-belt, which is favored by all customers.
