replacement drive belt has accurate transmission ratio, non-slip ratio will be constant, smooth transmission, smooth transmission, low noise, transmission ratio range, generally large 1:10, allowing line speeds of up to 40M / S, transmission power from a few watts to several hundred kilowatts. High transmission efficiency, compact structure, also adapted to multi-axis rotation, without lubrication, pollution-free, thus not permitted under the pollution and poor working environment more occasions to work properly. Has a good flex resistance, low elongation, high strength, heat, cold, anti-aging, ozone resistance, resistance to cracking and other advantages. Features: Model: 3M-420-12 Teeth number: 140 Belt length: 420mm(16-1/2") Peak distance between 2 adjacent belt teeth: 3mm(1/8").
