The 230 7B pulley is a V-belt drive pulley, section B, with a 230 mm diameter and 7 grooves. It is designed to drive shafts in industrial equipment where power needs to be transmitted with several belts in parallel, such as fans, compressors, pumps and conveyors. Its in-house manufacturing allows the machining to be adjusted to the mounting requirements. Request a quote on WhatsApp indicating the code POLEA 230 7B.

This item is a pulley with a 230 mm diameter, 7 grooves and section B. The designation POLEA 230 7B summarizes those three variables: size, number of grooves and belt profile. Section B corresponds to a type of V-belt widely used in medium-power industrial drives. Having 7 grooves allows up to seven belts of the same profile to be mounted on the same body, which distributes the load and increases the transmission capacity compared with a single-groove pulley.

Typical applications for a pulley of this type appear in machines that run many hours per day: centrifugal fans, screw compressors, centrifugal pumps, belt conveyors, mixers and process equipment. In all those cases the pulley is mounted on the shaft of the driving or driven equipment, and the number of grooves is chosen according to the power to be transmitted and the available space. It is also used in machine tools and in factory equipment that requires fixed transmission ratios.

To correctly select a 7-groove section B pulley, you must verify the shaft diameter, the fastening system (keyway, taper bushing or clamp), the center distance and the desired transmission ratio. The 230 mm diameter conditions the peripheral speed: the larger the diameter, the higher the belt speed for the same rpm. It is important to check the alignment between pulleys and the belt tension to avoid premature wear and vibration. If the original equipment has another size, an equivalent pulley can be evaluated.

If you need a pulley with a different number of grooves, another diameter or a different section, the most practical thing is to send the code or designation shown on the original part. With that data, a nearby size within the same series can be found or a compatible replacement can be evaluated. It is also advisable to provide the shaft diameter and the type of mounting to confirm that the pulley fits without modifications. MR Accesorios Industriales manufactures pulleys and can analyze the particular case.

To request a quote for this 230 7B pulley or ask about a variant, write on WhatsApp to MR Accesorios Industriales with the code POLEA 230 7B. If you have doubts about the equivalence with another brand or need a special size, send a photo of the old pulley and the equipment data. This way the right option can be confirmed and we can proceed with manufacturing or replacement.
