The POLEA 170 4C pulley is a V-belt drive pulley, manufactured by EMMAR Accesorios Industriales. It has a 170 mm diameter, 4 grooves and section C. It is used to transmit power from a motor to a machine, maintaining the speed ratio and parallelism between shafts. It is a key part in the maintenance of production lines, pumps, fans and conveyors. If you need to replace an existing pulley or build a new drive, this size and number of grooves cover medium and high load applications.

This item is a pulley with a 170 mm diameter, 4 grooves and section C. Section C corresponds to wide-profile V-belts, suitable for transmitting high power. The 4 grooves multiply the transmission capacity by using several belts in parallel. The 170 mm diameter defines the speed ratio together with the driven pulley. The part is manufactured at MR with dimensional control so that the grooves align correctly and the belt seats without premature wear.

Typical applications include machine tools, compressors, centrifugal pumps, industrial fans and conveyors. In all cases the goal is to transmit motion from an electric or combustion motor to equipment that requires lower speed and higher torque. It is also used to replace worn pulleys or to modify the transmission ratio on an existing machine. Being section C with 4 grooves, it withstands significant loads and is common in medium and high power equipment.

For correct mounting, check that the shaft has the right diameter and keyway, and that the pulley is aligned with the driven one. Belt tension must be the one recommended by the belt manufacturer; excessive tension wears bearings and low tension causes slipping. When selecting, take into account the power to be transmitted, the shaft rpm and the diameter of the driven pulley. If you need help with the calculation, contact us.

If you can't find the exact size, we can manufacture a custom pulley or find an equivalent in section C with another diameter or number of grooves. To do so, send us the part number POLEA 170 4C or the data of the original pulley: diameter, grooves, section and shaft diameter. We can also advise you if you need to change the transmission ratio. In-house manufacturing, EMMAR brand, allows us to adapt to special orders.
