The EMMAR 170 7B is a V-belt drive pulley built with a 170 mm diameter and seven grooves for section B belts. It carries power from a drive shaft to a driven shaft in equipment that runs continuously and needs a defined speed ratio. Because MR produces this pulley in its own shop, the design can be adjusted to suit different mounting arrangements.
Read the code first: POLEA 170 7B packs three variables into one designation, the diameter in millimeters, the groove count and the belt section. The pulley mounts on a shaft and moves the driven side through V-belts. Section B is common in medium-power industrial drives, and seven grooves spread the load across several belts, which lowers the strain on each belt and keeps the drive running smoothly.
You will find this pulley on industrial fans, centrifugal pumps, compressors, conveyor belts and machine tools. In each case it forms part of a drive that holds a set speed at the driven equipment. It also suits process machinery that needs some elasticity in the drive to soak up vibration or overloads. With seven grooves it handles moderate to high power in section B, provided the drive calculation calls for it.
When selecting the pulley, check the pitch diameter, groove count, belt section and the keyway or shaft fastening method. Confirm that the pulleys line up and that belt tension is correct, since misalignment or slack tension wears belts early. In tight spaces, verify the outside diameter and overall width before ordering. MR manufactures the pulley under dimensional control, but it is still worth comparing your measurements against the technical data sheet before installation.
For a replacement, send the part number POLEA 170 7B or the details of the pulley you are removing: diameter, grooves and section. A photo of the part and of the shaft it sits on works too. With that, MR reviews building a similar pulley or adapting an existing one. Ask about other groove counts or diameters as well, since in-house manufacturing lets us tailor the design to your equipment.
To request a quote on this pulley or other sizes, send the part number by WhatsApp or email to MR Industrial Accessories. We come back with the technical information and the manufacturing quote. You can also ask about section B belts, taper bushings or the fastening hardware that goes with the drive. Our team can suggest equivalents and help you pick the right component.

Frequently asked questions
- What does POLEA 170 7B tell me about the pulley?
- It identifies a pulley with a 170 mm diameter and seven grooves for section B belts. That is the standard way V-belt pulleys are labeled in the industrial market, and it captures the three key variables: diameter, groove count and belt section.
- Is this pulley made in-house under the EMMAR brand?
- Yes, it is produced in-house under the EMMAR brand. That means the design can be adapted to specific mounting requirements or a different number of grooves, within the available machining capability. Ask about variants.
- How do I request an equivalent pulley or a different size?
- Send the part number POLEA 170 7B by WhatsApp, or the data of the pulley you need to replace: diameter, grooves and section. A photo or sketch also helps. With that information we can evaluate manufacturing a similar pulley.
