The 210 4B pulley is a section B V-belt drive pulley, with a 210 mm diameter and four grooves. It is used to drive shafts from a motor, distributing power among several belts to transmit more torque without slipping. It is an in-house manufactured part, EMMAR Accesorios Industriales brand, designed for equipment that runs several hours a day and needs a balanced pulley, with machined grooves and good belt grip.

This pulley has a 210 mm outer diameter, 4 grooves and section B. The grooves are machined so that the section B V-belt seats evenly and does not come off. Being a four-groove pulley, it allows distributing the load among four belts, which reduces the wear of each one and improves transmission when the equipment starts under load. The mass and diameter are designed so that the pulley rotates without annoying vibrations within its working range.

It is used in screw compressors, industrial fans, mills, mixers, conveyor belts and production machines in general. It is also common in pumping equipment and in drives where the revolutions between the motor and the driven shaft need to be reduced or increased. Having four grooves, it is a common option when more power needs to be transmitted without increasing the pulley diameter or changing the belt section.

To mount it, verify that the shaft and the keyway are clean and free of burrs, and that the pulley fits without blows. Align the drive pulley and the driven pulley with a straightedge or a laser; a misalignment of a few degrees wears the grooves and the belts. Tension the belts according to the equipment manual and check the tensioner after the first hours of operation. If the pulley is mounted with a taper bushing, tighten the screws in a cross pattern and with the proper wrench.

If you need a pulley with another number of grooves, another diameter or a different section, it can be manufactured to measure. To request an equivalent or a nearby size, send us the part number of the original pulley, the number of grooves, the belt section and the outer diameter. A photo of the mounted pulley and the shaft size also work. With that data we confirm whether we have a similar pulley or whether it is better to manufacture it.

MR Accesorios Industriales manufactures this pulley locally, with dimensional control and balancing. If you want to request a quote for the 210 4B pulley or ask about a similar size, send the part number via WhatsApp and we will reply with the technical information you need for your equipment.
