The 650 3B pulley is a power transmission component designed to be mounted on shafts and transmit motion via section B V-belts. With 650 mm outside diameter and three grooves, it allows building high-capacity drives with controlled speed. It is a part manufactured by EMMAR Accesorios Industriales, designed for demanding applications requiring robustness and precise alignment.

This pulley has 650 mm diameter, 3 grooves and section B. It is manufactured by EMMAR, which guarantees quality control and special dimensions. Section B accepts classic profile belts, and the three grooves allow distributing the load among several belts, reducing individual stress and improving the assembly's reliability. The 650 mm diameter places it in the range of large pulleys, suitable for low to medium speed shafts with high torque.

It is used in belt drives of industrial machinery: mills, mixers, compressors, high-flow pumps, induced draft fans and continuous process equipment. It is also common in production lines where motor speed reduction and torque increase on the driven shaft are needed. Due to its size, it is usually mounted on robust shafts with keyway and fastening systems that withstand the radial loads typical of the drive.

To correctly select this pulley, take into account the pitch diameter, number of grooves and belt section. Verify the allowable peripheral speed and the torque to be transmitted. During mounting, ensure alignment between pulleys to avoid irregular belt wear and vibrations. Use all grooves if the design requires it and check dynamic balancing, especially in high-speed applications.
