For drives that rely on a single B-section V-belt, this 650 mm diameter pulley from EMMAR delivers the size and groove configuration needed to keep fans, compressors, pumps, mixers and similar equipment running. It is manufactured in-house with attention to critical dimensions so it fits the shaft and accepts the belt as intended.
The part number POLEA 650 1B tells you most of what you need: 650 is the outside diameter in millimeters, 1 is the number of grooves, and B is the V-belt section. That combination suits moderate transmission ratios where one belt handles the load. Because it is produced under our own manufacturing program, you get a pulley that is checked for the dimensions that matter during installation.
Typical uses include industrial fans, screw compressors, centrifugal pumps, mixers and conveyors, as well as agricultural and process machinery. The large diameter supports suitable peripheral speeds for medium and high capacity drives. Since it takes a section B belt, it works with standard belts of that profile.
Before you order, gather the shaft diameter, keyway type and fastening method (set screw, cone or bushing). Confirm the belt is section B and that one groove matches your drive. During mounting, keep the pulley and shaft clean and free of burrs, align the groove with the driving pulley, and set belt tension per the equipment manual. Too much tension overloads bearings; too little causes slipping.
If you need a different diameter, groove count or section, we can manufacture it or locate an equivalent. Send the code POLEA 650 1B or the full designation through WhatsApp, along with your shaft data and the belt you use. MR also manufactures housings, chains and pulleys, and supplies bearings and power transmission products.
For compatibility questions, share as much detail as possible: shaft diameter, keyway type, center distance and power to be transmitted. Our team will help you confirm the right pulley for the job.

Frequently asked questions
- What does POLEA 650 1B mean?
- The 650 is the outside diameter in millimeters, and 1B means one groove for a section B V-belt. It is a large diameter pulley designed to transmit power with a single belt.
- How do I request a pulley with a different size or number of grooves?
- Send the current code or full designation via WhatsApp, along with the shaft diameter, keyway type and belt section. We will quote a custom pulley or an equivalent.
- What should I check before mounting the pulley?
- Make sure the shaft and keyway are clean and free of burrs, and that the belt is section B. Align the groove with the driving pulley and adjust tension according to the equipment manual. Incorrect tension can wear the belt or overload the bearings.
