The 230 4B pulley is a V-belt drive pulley, section B, with 230 mm diameter and four grooves. It is used to transmit power between parallel shafts in industrial equipment, where a stable transmission ratio and good heat dissipation are required. MR Accesorios Industriales manufactures and sells it within its power transmission line, along with belts, bushings and housings.

This item is a pulley with 230 mm diameter, 4 grooves and section B. The designation POLEA 230 4B summarizes those three variables: the 230 mm outer diameter, the number of grooves (4) and the belt section it houses, B. The grooves are machined so that the V-belt seats uniformly and contact is distributed along the entire arc. It is an in-house manufactured part, EMMAR brand, designed to be mounted on shafts with taper bushing or hub, depending on the equipment.

Typical applications appear in transmission lines where speed must be multiplied or reduced: fans, centrifugal pumps, screw compressors, conveyor belts, mixers and continuous process machines. It is also used in auxiliary drive equipment, such as exhausters or blowers. Having four grooves allows the load to be distributed among several belts, which reduces the stress on each one and improves service continuity when a belt wears.

To select the correct pulley, the shaft diameter, mounting type and belt section must be verified. Section B accepts B-profile belts, and the number of grooves must match the driving pulley. During mounting, it is advisable to align the pulleys with a straightedge or laser, tension the belts according to the equipment manual and check that there is no slipping. A misaligned pulley or one with worn grooves accelerates belt wear and generates vibration.

If you need a pulley with a different number of grooves, another diameter or a different section, an equivalent can be evaluated. To do so, send us the part number POLEA 230 4B along with the equipment data: shaft diameter, belt section, number of grooves and mounting type. With that information we look for the alternative that best fits without modifying the rest of the system.
