The 420 1C pulley is an in-house manufactured power transmission pulley, EMMAR brand, with a 420 mm diameter and one groove for a section C belt. It is used to drive machine shafts from a motor, transmitting rotation by means of a V-belt. It is a key part in equipment where speed needs to be reduced or increased simply and robustly.

This pulley has a 420 mm diameter, 1 groove and is designed for section C belts. The designation 420 1C sums up those three characteristics: the outside diameter, the number of grooves and the belt section it takes. It is a single-groove pulley, designed for transmissions that require a fixed speed ratio and direct mounting on the shaft.

It is used in industrial fans, compressors, centrifugal pumps, mills, mixers and conveyors. It also appears in agricultural machinery and process equipment where the mounting space is ample and a large-diameter pulley is needed to achieve low speed with good torque. It is common in installations where the motor runs at high speeds and the aim is to reduce the revolutions of the driven shaft.

To select it, take into account the shaft diameter, the type of keyway and the fastening system (set screw, taper or bushing). Check that the section C belt matches the groove and that the center distance allows correct tensioning. The pulley must be balanced and aligned with the drive pulley to avoid vibrations and premature belt wear. If the equipment runs with variable loads, choose a diameter that does not oversize the peripheral speed.

If you need a pulley with a different number of grooves, another diameter or for a different section, we can manufacture it. Send us the part number POLEA 420 1C or the size you are looking for and we will give you the alternative that best suits your machine. We can also advise you on the type of bushing or taper if you do not have that data at hand.
