Single sprocket (product release, mandatory): Compared with the double sprocket roller, single sprocket roller easy installation and removal, and may need to select the roller center distance. Standalone length smaller. Through the bottom or top of the chain drive to the roll. The mounting accuracy is less than 0.5mm. The maximum length of the chain drive by breaking load and payload weight limits. Large capacity, high speed, speed over 30 m / min noise, abrasion, number of teeth = 11,13,14, equipped with 08B chain, to be injected into the oil. Carbon double sprocket (product release, mandatory): Compared with single sprocket roller, double sprocket roller chain guide plate is not required, but is determined by the spacing of the roller chain pitch, the need to ensure tight tolerances. The maximum unit length is determined by the maximum fracture load chain. In the motor when the chain to withstand the maximum load. Large capacity, high speed, speed over 30 m / min noise, abrasion, number of teeth = 11,13,14, equipped with 08B chain, to be injected into the oil. Steel sprocket (product release, mandatory): The most prominent advantage is low noise, for 30 m / min or more cases. Abrasion resistance is good, but somewhat less than the steel sprocket. Teeth = 14 or 11 teeth, equipped with 08B chain, without a regular infusion of oil bearing capacity smaller. Steel sprockets made of fiber reinforced PA66 + + antistatic agents. Single-stranded and double-stranded same as the difference between carbon steel sprocket. Timing Pulleys: Material for POM, gear belt running low noise, no maintenance. Suitable high speed. Roller center distance tolerance for 0-0.3mm. Serrated belt pitch 8MM, serrated belt width 11.2MM, teeth 18 teeth
