The 310 1B pulley is a power transmission component manufactured by EMMAR Accesorios Industriales. With a 310 mm diameter and one groove for section B belts, it transmits motion from a drive shaft to a machine or between shafts. It is used in industrial equipment that requires a simple and reliable transmission ratio, such as fans, pumps, compressors and conveyors. Its metal construction and precise machining ensure balanced rotation and a long service life in continuous operation.

The 310 1B pulley has a 310 mm outer diameter and a single groove for a section B belt. This section corresponds to classic-profile belts with a nominal top width of 17 mm, although the exact groove dimensioning is confirmed in the manufacturer's technical data sheet. The 310 mm diameter places it in a medium size range, suitable for moderate transmission ratios. The material and surface treatment are not specified in the record, so we recommend contacting MR to learn about the options available for your application.

This type of pulley is used in machines that need to transmit power between parallel shafts with a V-belt. Typical applications include centrifugal fans, centrifugal pumps, screw compressors, belt conveyors and process equipment in industrial plants. It is also used to replace worn or damaged pulleys in existing installations, where the original transmission ratio must be maintained. Its single-groove design simplifies mounting and reduces alignment requirements compared to multi-groove pulleys.

To correctly select a 310 1B pulley, take into account the pitch diameter, which determines the belt's tangential speed and the transmission ratio. Verify that the keyway and bore diameter match the drive shaft. Alignment between pulleys is critical to avoid premature belt wear and vibration. Make sure the section B belt is suitable for the groove and that the tension is the one recommended by the belt manufacturer. If you need help calculating the transmission ratio, contact MR.
