Description
EMMAR POLEA 380 3B 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 380 3B and any equivalents.
This EMMAR pulley, identified as POLEA 380 3B, is a 380 mm diameter, 3-groove, section B sheave. It mounts on a shaft to transfer motion from a motor to driven equipment. With three grooves, the load can be shared across three B-section belts, which suits medium-torque drives. MR Industrial Accessories manufactures this pulley in-house, with dimensional checks on each unit.
The code breaks down simply: 380 for the diameter in millimeters, 3 for the number of grooves, and B for the belt cross-section. That makes it part of the section B pulley series produced by MR. Because the grooves are machined on a lathe, concentricity and proper belt seating are maintained.
You will find this size in industrial plants on fans, compressors, centrifugal pumps, conveyors and machine tools. It also appears on agricultural implements and in shops that assemble or replace belt drives. Since it is made in-house, the bore and keyway can be adapted to the shaft you have.
When selecting a replacement, confirm the pitch diameter, groove count and belt section. Check that the shaft diameter and keyway match, and that the paired pulley still gives the transmission ratio you need. Proper alignment between pulleys helps prevent belt and bearing wear. For drives with variable loads, check belt tension on a regular schedule.
If your drive calls for a different diameter, groove count or section, MR can manufacture it. Send the part number POLEA 380 3B, or the shaft and belt details, and the team will quote a pulley from the same series. Custom bore and keyway are also possible when you provide a drawing or shaft dimensions.
To request a quote or ask about a variant, message MR Industrial Accessories on WhatsApp or by email with POLEA 380 3B. The team replies promptly with machining options. If you are unsure which pulley fits, send a photo or assembly drawing and they will help you identify the right model.
