The 420 2A pulley is a V-belt transmission pulley, manufactured by EMMAR Accesorios Industriales. It has 420 mm diameter, two grooves and section A. It is used to transmit power between parallel shafts in machines and industrial equipment, where a reliable transmission ratio and good belt grip are needed. Being of in-house manufacturing, we can adjust the machining and balancing according to the application. If you need to replace an existing pulley or build a new transmission, send us the part number and we will quote you.

This pulley has 420 mm diameter, 2 grooves and section A. Section A corresponds to classic V-belts of narrow profile, widely used in industrial power transmissions. The two grooves allow mounting two belts in parallel, which increases transmission capacity and gives redundancy: if one belt fails, the other continues transmitting until it is replaced. The 420 mm diameter places it in the range of large pulleys, typical of low or medium speed shafts. Machining is done in our facilities, with dimensional control and balancing.

Typical applications of a pulley of this size and section include industrial fans, centrifugal pumps, screw compressors, screens, conveyor belts and continuous process machines. It is also used in mining, cement and aggregate processing plants, where transmissions work many hours per day. In all these cases, the pulley must be well aligned and balanced to avoid vibrations and premature wear of belts and bearings. Section A is suitable for medium power and moderate peripheral speeds.

To correctly select a 2-groove section A pulley, take into account the pitch diameter, the number of grooves, the type of bore (cylindrical or tapered) and the fastening system (keyway, taper bushing or press fit). Verify the center distance and the desired transmission ratio. The 420 mm diameter conditions the peripheral speed: at higher speed, more balancing demand. During mounting, align the pulleys with a ruler or laser, tension the belts according to the manufacturer's manual and periodically check tension and wear. A misaligned pulley shortens the service life of the entire assembly.
