The pulley 120 7B is a power transmission pulley manufactured by EMMAR Accesorios Industriales. It has a 120 mm diameter, 7 grooves and section B. It is used to transmit motion from a motor to a machine by means of V-belts. It is a key part in transmission systems that require several speed ratios or high torque. Its robust construction makes it suitable for continuous service in demanding industrial environments.

This pulley has a 120 mm outer diameter, 7 grooves and section B. Section B corresponds to classic V-belts with a B profile, with a nominal top width of 17 mm. The 7 grooves allow transmitting more power than a pulley with fewer grooves of the same diameter. It is manufactured by EMMAR, with dimensional and balancing control for smooth operation. It is mounted on cylindrical shafts and fastened with a key and set screw or taper bushing, depending on the equipment design.

It is used in industrial machines such as compressors, pumps, fans, mills, mixers and conveyors. It is common in production lines where the speed of a piece of equipment needs to be varied without changing the motor. It is also used in low-speed, high-torque drive equipment, where the number of grooves helps distribute the load. Due to its compact diameter, it is suitable for reduced spaces that require transmitting considerable power.

To select the correct pulley, take into account the power to be transmitted, the shaft speed, the transmission ratio and the type of belt. Verify that the pitch diameter is compatible with the section B belt and that the number of grooves covers the required power. Check the alignment between pulleys and the belt tension to avoid premature wear. If the shaft has a larger diameter than the pulley bore, a bushing can be machined or a pulley with a larger bore can be chosen.

If you need a pulley with a different number of grooves, another diameter or a different section, we can manufacture it or find an equivalent. For that, send us the part number of the original pulley, the complete designation or the shaft and belt measurements. We can also advise you if you do not have the designation at hand. At MR Accesorios Industriales we manufacture pulleys and other transmission components, and we distribute bearings, housings, chains and seals.
