The MR industrial pulley, 260 mm with one groove for a section B belt, is a power transmission component designed to be mounted on shafts and transmit motion via V-belts. It is used in a wide variety of industrial equipment, from fans and pumps to conveyors and machine tools. Its robust construction and precise machining allow reliable operation in continuous applications. As it is in-house manufacturing, brand EMMAR, it can be adapted to specific requirements of diameter, number of grooves and hub type.

This MR pulley has an outside dimension of 260 mm, a single groove and is designed for section B belts. Section B is one of the most widely used in medium-power industrial drives, and the 260 mm diameter allows suitable transmission ratios for moderate speeds. The groove is machined with tolerances that ensure correct belt seating, reducing wear and vibration. It is important to note that the pulley is supplied without a hub or with the hub specified at the time of inquiry, as MR manufactures this component according to the requirements of each application.

Section B pulleys with 260 mm diameter and one groove are typically used in centrifugal fans, centrifugal pumps, screw compressors, belt conveyors, mixers and process equipment in general. They are also common in the agro-industrial sector, in water treatment plants and in the food industry. Their design allows mounting on both horizontal and vertical shafts, provided that proper alignment and tension are maintained. As part of a drive system, selection must consider the power to be transmitted, shaft speed and environmental conditions.

For correct mounting, verify that the shaft has the diameter and keyway length compatible with the selected hub. The pulley must be perfectly aligned with the drive pulley to avoid irregular belt wear and unnecessary stress on the bearings. Belt tension must be as recommended by the belt manufacturer; excessive tension accelerates bearing wear, while low tension causes slippage and loss of efficiency. In applications with high peripheral speeds, balancing the pulley-shaft assembly is recommended to minimize vibration.

If you need an equivalent pulley or a nearby size, the most practical approach is to send us the exact code on the part or on the drawing. With that data, at MR Accesorios Industriales we can identify the series, section and diameter, and offer you alternatives within our in-house manufacturing line. We can also manufacture a custom pulley if none of the standard sizes fit your requirement. The more data you provide — outside diameter, number of grooves, section, hub type and shaft diameter — the faster the response.

To request a quote for this pulley or inquire about a variant, send us the code POLEA 260 1B via WhatsApp along with the quantity and hub details if you have them. The technical team at MR Accesorios Industriales will respond with available options and manufacturing lead times. Remember that as an in-house manufactured product, we can adjust the design to your specific transmission needs.
