The POLEA 140 3B is a V-belt drive pulley from the EMMAR line, built in-house. It measures 140 mm in diameter and carries three grooves for section B belts. Its job is to move power between parallel shafts on industrial machinery, and it sits within the power transmission range we supply.
Reading the part number is straightforward: the first figure gives the diameter, the second gives the groove count, and the letter gives the belt profile. So this is a 140 mm pulley, 3 grooves, section B. Section B belts are a common choice for medium-power drives, and because the pulley is made in-house, the groove machining and balancing are handled to suit the application.
Typical installations include fans, pumps, compressors, conveyors, mixers and machine tools, as well as any setup where the speed ratio between a motor and the driven machine has to be set. With three grooves, the load is shared across the belts rather than carried by one, which lowers the strain on each belt. You will find this style of pulley throughout plants, factories and continuous-process equipment.
When selecting one, work from the pitch diameter, the groove count and the belt section. Check that the bore and keyway match the shaft, and that the pulleys line up with each other; misalignment leads to uneven belt wear. Tension the belts as the equipment manual specifies. If a different ratio is needed, an equivalent or another groove count can be reviewed.
If you are matching a replacement or sizing a different pulley, send the original part number along with the groove count and belt section. Outside or pitch diameter and shaft diameter are also useful. With those details we can point you to the right option in the EMMAR manufacturing line or among the brands we carry.
