Description
EMMAR POLEA 650 3C 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 650 3C and any equivalents.
The POLEA 650 3C is a section C V-belt pulley with a 650 mm diameter and three grooves. It is designed for driving large shafts in industrial equipment where multiple belts transmit power in parallel. As an in-house manufactured EMMAR product, the machining can be tailored to the required bushing or bore size.
The part number POLEA 650 3C encodes the key specifications: 650 mm diameter, 3 grooves, and section C profile. Section C refers to wide-profile V-belts used for higher power transmission than smaller sections. The three grooves allow three belts to run side by side, sharing the load and reducing stress on each belt.
This pulley is commonly found in low-speed, high-torque applications such as mills, mixers, screens, conveyor drives, high-flow exhausters, and continuous process machinery. It also suits gear reducers and drives with large shaft diameters. Selection depends on outside diameter, number of grooves, and the bushing or bore type.
When installing a 650 mm three-groove pulley, check alignment with the mating pulley, belt tension, and groove condition. Misalignment or worn grooves can accelerate belt wear and cause vibration. Verify that the bushing or tapered bore matches the shaft diameter and fastening system. For variable loads, the number of grooves and section should be determined together with the drive calculation.
If you need a different number of grooves, another diameter, or a different section, request an equivalent. Provide the part number POLEA 650 3C or the equipment data: pulley diameter, belt section, number of grooves, and shaft size. With that information, we can evaluate whether an in-house manufactured pulley with appropriate machining is the best fit or if another power transmission option is suitable.
MR Industrial Accessories manufactures this pulley and other transmission components in its own facilities. If you have questions about the designation, number of grooves, or bushing type, contact us via WhatsApp or email with the part number POLEA 650 3C. Our team will help confirm the part and suggest equivalents before quoting.

Frequently asked questions
- What does the designation POLEA 650 3C indicate?
- It indicates a pulley with a 650 mm diameter, 3 grooves, and section C. This code identifies the part by size, number of grooves, and belt profile. If your equipment uses a different number of grooves or section, a variant with the same diameter can be requested.
- Is this pulley manufactured in-house by EMMAR?
- Yes, it is in-house manufactured under the EMMAR brand. This allows the bore or bushing machining to be adjusted to match the equipment shaft. To confirm the exact variant, send the part number and shaft data via WhatsApp or email.
- How do I request an equivalent pulley?
- Send the part number POLEA 650 3C or the equipment data: diameter, belt section, number of grooves, and shaft size via WhatsApp or email. We will evaluate the alternative and quote the part that best fits.
