The 130 3B pulley is a V-belt drive pulley manufactured by EMMAR Accesorios Industriales. It has a 130 mm diameter, 3 grooves and section B, which makes it suitable for transmitting power in equipment that requires several belts in parallel. It is used in industrial machines, compressors, fans and drive systems where a compact-size pulley with good drive capacity is needed. Because it is in-house manufactured, machining variants can be requested according to the equipment's needs.

This pulley has a 130 mm diameter, 3 grooves and section B. Section B corresponds to V-belts with a B profile, and the three grooves allow three belts to be mounted in parallel on the same pulley. The 130 mm diameter places it in a small to medium size range within the section B pulley line. It is designed to be mounted on shafts and to transmit motion from a motor to another component of the system.

Typical applications of a 3-groove section B pulley include screw compressors, centrifugal fans, pumps, conveyor belts and machine tools. In all cases, the goal is to transmit torque with several belts to distribute the load and reduce wear on each one. It is also used in equipment where a certain redundancy is needed: if one belt fails, the other two keep transmitting until the replacement is made.

To correctly select this pulley, take into account the pitch diameter, the number of grooves and the belt section. Section B requires the belt to be of the same profile; do not mix sections. Check that the shaft has the appropriate diameter and keyway, and that the fastening system (set screw, taper bushing or plate) is compatible. Alignment between pulleys is key to avoid irregular belt wear and vibrations.
