The 250 6B pulley is a section B V-belt drive pulley, with a 250 mm diameter and 6 grooves. It is used to drive machine shafts from a motor, transmitting torque and regulating speed according to the combined diameters. It is a machined cast part, designed to work continuously in industrial equipment. MR Accesorios Industriales manufactures and sells it as part of its own power transmission line.

This pulley has a 250 mm outside diameter, 6 grooves and section B. Section B is one of the most widespread V-belt sizes in industry, and the 6 grooves allow power to be distributed among several belts, which provides more transmission capacity and some tolerance to the failure of one belt. The 250 mm diameter defines the drive ratio when combined with the motor pulley. It is an in-house manufactured part, EMMAR brand, with machined grooves and balancing to rotate without vibrations.

It is used in machines that need to transmit power from an electric motor or a gear reducer: screw compressors, industrial fans, centrifugal pumps, conveyor belts, mixers and process equipment. Also in the field, in agricultural implements and in treatment plants. When the equipment runs many hours a day, the cast pulley with well-machined grooves makes a difference in belt service life and noise level.

To install it, verify that the shaft and keyway are clean and free of burrs, and that the pulley fits with a tolerance that does not allow radial play. Align the pulleys with a straightedge or a laser: a misalignment of a few degrees accelerates wear on the belts and the equipment's bearings. Belt tension is adjusted according to the machine manufacturer's manual; if you do not have it, aim for the belt to give just enough when pressed with a finger. Check balancing if the pulley rotates at high speed.

If you need an equivalent pulley or a nearby size, send us the full part number, the number of grooves and the diameter. It also helps if you tell us the belt section you use, the shaft diameter and the type of keyway. With that data we can see whether there is a pulley in our line that replaces the one you have or whether it is better to manufacture it to measure. If the original pulley has no legible marking, send us a photo and the dimensions taken with a caliper.

MR Accesorios Industriales manufactures pulleys, split plummer block housings and ANSI chains, and sells bearings, seals, bushings and lubricants. If this 250 6B pulley fits your equipment, send the part number by WhatsApp and we will provide the quote. If you are unsure about the size, write to us anyway: we will help you identify it with the data you have on hand.
