The 280 1B is a single-groove, B-section V-belt pulley with a 280 mm diameter, manufactured in-house under the EMMAR brand. It transfers motion from a motor or gearbox to a driven shaft in machines that use simple ratios and V-belts. The metal body and machined groove help the belt seat correctly and wear evenly in continuous operation.

The designation 280 1B indicates a pulley with a 280 mm diameter and one groove for a B-section belt. Section B is a common V-belt profile in medium-power industrial drives. With a single groove, the pulley runs one belt and fits drives that do not require parallel strands. MR produces this pulley in its plant, with dimensional control on the diameter and groove profile.

You will find this type of pulley on fans, compressors, centrifugal pumps, light conveyor belts, mixers, and general factory equipment. It also serves as a replacement for a worn pulley or to change the transmission ratio of an existing machine by swapping the driving or driven pulley diameter. In every case, confirm that the belt is B section and that the diameter suits the permissible linear speed of the equipment.

When selecting or mounting a single-groove B-section pulley, check the pitch diameter, shaft diameter, and fastening method (keyway, set screw, or taper bushing, as applicable). Align the groove with the opposite pulley to prevent uneven belt wear and vibration. Also inspect belt tension and shaft bearing condition: a new pulley will not correct an existing misalignment. For variable loads, consider a larger diameter or more grooves.

If you need a different size, groove count, or section, ask for an equivalent from the same manufacturing line. Provide the current part number, diameter, number of grooves, and belt section, and we will confirm the matching reference. We can also manufacture to measure if the shaft or keyway does not match standard, as long as you send the drawing or relevant dimensions.

To request a quote for the 280 1B pulley or ask about a variant, send the part number MR-POLEA-B1-280 by WhatsApp. If you are unsure about an equivalent, include a photo of the part and the shaft size. MR manufactures pulleys, split plummer block housings, and ANSI roller chains, and supplies bearings, seals, bushings, and lubricants for industrial maintenance.
