The EMMAR POLEA 170 4A is a V-belt pulley with a 170 mm outside diameter, four grooves, and a section A profile. It mounts on a driven shaft to transfer power from a motor, and running multiple belts in parallel increases the torque the drive can handle without slipping. This pulley is manufactured in-house by MR, with the bore, groove width, and outside diameter checked so the belts run true.
Section A refers to the classic narrow V-belt profile. The four grooves let you run four A-section belts side by side on the same sheave. The 170 mm diameter sets the ratio when paired with the other pulley in the drive. Because the grooves and bore are machined to controlled dimensions, the belts sit at a consistent depth and share the load evenly.
Typical installations include machine tools, air compressors, industrial fans, centrifugal pumps, belt conveyors, mixers, and process equipment. When a drive needs more torque capacity than a single- or two-groove pulley can provide, a four-groove unit like this one is often specified while keeping the same diameter. It also works where speed must be stepped up or down using A-section belts.
Before installing, confirm the belt profile is A and that the groove count matches the number of belts you plan to use. Measure the bore and check the keyway type on the shaft. Alignment between the driving and driven pulleys matters: angular or parallel misalignment speeds up wear on the belt flanks. Follow the equipment manual for tension, and verify balancing if the pulley turns at high speed.
If your drive calls for a different diameter, groove count, or section, send the current pulley diameter, belt section, number of grooves, and shaft diameter. MR can supply or manufacture an equivalent pulley. If the part number is not available, a photo of the installed pulley plus a caliper reading of the outside diameter helps identify the correct replacement.

Frequently asked questions
- What do the 4 grooves and section A mean?
- The pulley accepts four A-section V-belts side by side. That arrangement allows the drive to transmit more power than a pulley with fewer grooves, provided the rest of the drive is set up for that many belts.
- How can I tell if this pulley replaces the one on my machine?
- Check the outside diameter, groove count, belt section, and bore diameter with keyway. If those match, it is compatible. If not, send a photo and measurements via WhatsApp for confirmation.
- Can I get a pulley with a different diameter or number of grooves?
- Yes. MR manufactures pulleys in various sizes and configurations. Send the diameter, section, and groove count you need by WhatsApp, and the team will quote an equivalent or better-suited part.
