Synthetics, bi-material leather and cotton-ply rubber.
Flat belts for power transmission must meet stringent requirements in terms of traction, efficiency and speed.
Synthetic belts (Nitta brand), the latest generation of flat belts, incorporate a polyamide tensile strength core with two wear-resistant outer elastomer friction layers.
As the drive is a friction drive, torque transmission depends on the installation tension and the coefficient of friction between the working face of the belt and the surface of the Pulley.
TA Flat belt - synthetic belt (NITTA supplier)
Belts made up of two friction layers of acrylic nitrile, better known under the general term "elastomer".
"elastomer".
The PA6 polyamide tensile member at the centre of the Belt is made from heated granules, extruded and then stretched to form a compact element.
The antistatic polyamide fabric placed between the tension member and the friction layers reduces the static electricity generated by the rotation of the Belt (electromotive phenomenon).
Chromamide Belt - Bi-material leather
Belts made up of two layers of leather friction and a polyamide traction element.
Their main advantage is that they can accept slippage thanks to their leather friction layers, which are in contact with the Pulleys.
Rubber Belt with cotton interlining
Belts made from several plies of cotton canvas impregnated with rubber and vulcanised together.
The edges are coated with a red protective layer.
Their main advantage is that they can be stapled together.
