EMMAR POLEA 420 6B 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 420 6B and any equivalents.
The POLEA 420 6B is a power transmission pulley made by EMMAR. It has a 420 mm diameter and 6 grooves designed for section B belts. This pulley transmits motion between parallel shafts in industrial machinery, distributing the load across multiple belts to maintain a stable rotation speed. As an in-house manufactured item, customized machining and balancing options are available upon request to suit your application.
This pulley is identified by its key specifications: 420 mm diameter, 6 grooves, and section B compatibility. The part number POLEA 420 6B directly indicates these three attributes. Section B is a standard industrial belt profile, and the 6 grooves allow multiple belts to share the power load. The bore, keyway, and balancing are machined to match your shaft and operating speed requirements.
Common applications include fans, centrifugal pumps, compressors, mills, conveyor belts, and continuous process machines. It is frequently used where the motor and driven equipment are separated and a speed change is needed through diameter ratio. You will also find it in refrigeration equipment, plant exhausters, and production lines that run many hours a day, where belt drives offer simple maintenance and predictable performance.
When selecting this pulley, consider the power to transmit, the rpm of the faster shaft, the pitch diameter, and the number of grooves required to avoid overloading each belt. Verify the shaft diameter, keyway length, and fastening type. During installation, align the pulleys with a straightedge or laser, tension the belts according to the manufacturer's manual, and check shaft parallelism. Even slight misalignment can reduce belt life and affect equipment bearings.
For a different number of grooves or a pulley for another section, send the part number POLEA 420 6B via WhatsApp along with your equipment data: shaft diameter, rpm, power, and center distance. Our team will review alternatives within the EMMAR in-house manufacturing line and provide a quote. Special machining on the same base is also available.
MR Industrial Accessories LLC manufactures this pulley and integrates it into its power transmission line, which also includes housings, chains, and bearings. If you have the part number, send it via WhatsApp and we will reply with a quote. If you don't have it, describe the pulley by diameter, grooves, and section, and we will locate it for you.
