PU Timing Belt

PU timing belt is made of PU material, with excellent properties such as high strength, wear resistance, anti-aging, resistant to grease and chips, etc., and can operate stably for a long time in a high-load, high-precision transmission environment. Its tooth shape is precise, the transmission has no slip, high efficiency and low noise. It is widely used in CNC machine tools, precision instruments, industrial robots, food packaging and other industries, especially suitable for working conditions that require durability, precision and cleanliness. Compared with traditional rubber timing belts, PU materials have a longer lifespan, adapt to complex environments, and ensure efficient and reliable operation of mechanical equipment.

Synchronous pulley consists of a circular belt with evenly spaced teeth on its inner circumference and a correspondingly engaging pulley. It combines the advantages of belt drives, chain drives, and gear drives. During transmission, power is transferred through the meshing of the belt teeth with the pulley's tooth grooves.
Synchronous pulley offers precise transmission ratios, no slippage, and constant speed ratios, ensuring smooth operation, vibration absorption, low noise, a wide range of transmission ratios (up to 1:10), and allowable linear speeds of up to 50 m/s. It can transmit power from a few watts to hundreds of kilowatts. With high transmission efficiency, generally reaching 98%, it is compact, suitable for multi-shaft transmission, and requires no lubrication, making it pollution-free and ideal for environments where contamination is not allowed or where working conditions are harsh.
