Description
EMMAR POLEA 90 4B 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 90 4B and any equivalents.
The POLEA 90 4B is a power transmission pulley manufactured in-house by EMMAR. It has a 90 mm diameter, 4 grooves, and section B. This pulley transmits motion between shafts using V-belts, allowing speed changes in machinery and equipment. Because it is produced in our own facility, it can be made in various sizes and groove configurations to suit specific applications.
The part number POLEA 90 4B indicates three key attributes: a 90 mm diameter, 4 grooves, and section B. Section B refers to V-belts with a B profile, and the four grooves allow multiple belts to run in parallel on the same pulley. Machining takes place in our factory, with dimensional checks on the grooves and the central bore.
Typical uses include belt drives on machine tools, compressors, fans, pumps, conveyor belts, and process equipment. It also appears in agricultural implements and older machines where a worn or custom pulley needs replacement. With four grooves, it is common in drives that transmit considerable power with section B belts or where load is distributed across several belts to reduce wear.
When selecting this pulley, consider the pitch diameter, number of grooves, belt section, and the bore or bushing type required for the shaft. Also check center distance and available belt length, as the transmission ratio depends on them. For shafts with a keyway, confirm the keyway size and shaft diameter before manufacturing. Balancing and concentricity are important at high speeds.
If you need a different diameter, another number of grooves, or a different section, the pulley can be manufactured to order. To request an equivalent, send the part number POLEA 90 4B or the original pulley data: diameter, grooves, section, shaft diameter, and mounting type. We will quote the closest part or manufacture it in the required size.
MR Industrial Accessories LLC manufactures this pulley at its facility and offers it as part of its power transmission line. If you have questions about equivalence with another pulley or want to confirm whether this size fits your machine, contact us via WhatsApp or email with the part number and equipment details. We will respond with a quote.
