The EMMAR 120 7B pulley is a power transmission component with a 120 mm diameter, 7 grooves, and section B. It transfers motion from a motor to driven equipment through V-belts and is built for continuous duty in industrial settings.

This pulley measures 120 mm across and carries seven grooves in section B. Section B refers to the classic V-belt profile with a nominal top width of 17 mm. Seven grooves allow the drive to handle more power than a pulley with fewer grooves at the same diameter. EMMAR manufactures it with dimensional and balancing checks for smooth running. It mounts on cylindrical shafts and is secured with a key and set screw or a taper bushing, depending on the machine design.

Typical installations include compressors, pumps, fans, mills, mixers, and conveyors. It is often found on production lines where equipment speed must change without swapping the motor. Low-speed, high-torque drives also use this pulley because the groove count spreads the load. The compact diameter suits spaces where substantial power must be transmitted in a limited footprint.

When selecting a pulley, consider the power to be transmitted, shaft speed, transmission ratio, and belt type. Confirm that the pitch diameter matches the section B belt and that the number of grooves covers the required power. Check pulley alignment and belt tension to prevent premature wear. If the shaft is larger than the pulley bore, a bushing can be machined or a pulley with a larger bore can be supplied.

If you need a different groove count, diameter, or section, we can manufacture it or locate an equivalent. Send the original part number, the complete designation, or the shaft and belt measurements. Our team can also assist if you do not have the designation handy. MR Industrial Accessories manufactures pulleys and other transmission components, and distributes bearings, housings, chains, and seals.
