Size: HTD5M (High Torque Drive) timing belt with 5 mm pitch, curved shape for better power transmission and reduces the risk of slipping. Strap material: timing belts are made of durable rubber (neoprene) with reinforced nylon cords. These materials provide high tensile strength, flexibility and abrasion resistance that the belt needs to withstand the high temperatures and forces in the engine. Application: widely used in various industrial applications, including robotics, automation systems, 3D printers, printing machines, CNC machines and other power transmission systems. Feature : The rubber timing belt ensures precise rotation ratio, prevents slipping, ensures precise power transmission, provides smooth operation, absorbs vibration, produces low noise, supports speed ratios up to 1:10, and achieves high transmission efficiency of 98%-99%. Note: There are several sizes available. Please confirm the size before ordering.
