Description
EMMAR POLEA 310 1B belongs to pulleys, part of our Power transmission range. Tell us how many you need by WhatsApp or email and we'll get back to you promptly with a quote for POLEA 310 1B and any equivalents.
The 310 1B is a single-groove V-belt pulley with a 310 mm outer diameter, designed for section B belts. It transfers power between parallel shafts in fans, pumps, compressors, conveyors and other industrial machinery. MR produces this pulley in its own machine shop, so dimensions and machining stay consistent from one unit to the next.
The code tells you most of what you need: 310 is the outer diameter in millimeters, 1 is the number of grooves, and B is the belt section. Section B covers classic-profile belts with a nominal top width of 17 mm; always confirm the exact groove dimensions against the technical data sheet before installing. At 310 mm, this pulley sits in the medium size range and works well for moderate speed ratios.
Typical installations include centrifugal fans, centrifugal pumps, screw compressors, belt conveyors and process equipment. The single groove makes mounting straightforward and keeps alignment simpler than a multi-groove setup. It is also a practical replacement for a worn or damaged pulley when the original transmission ratio has to be maintained.
When selecting a 310 1B, check the pitch diameter first, since it sets the belt speed and the ratio. Match the bore and keyway to the drive shaft, align the pulleys carefully to prevent vibration and early belt wear, and use a section B belt tensioned to the belt maker's recommendation. If you need help working out the ratio, contact MR.
If the 310 1B is not listed or you need a different size, send a quote request by WhatsApp. MR manufactures custom pulleys and can supply alternatives in other sections or diameters. For an equivalent, include the original part number, belt section, outer diameter, and bore diameter with keyway. Two-groove and larger-groove-count pulleys are also available when the application calls for more capacity.
