Description
EMMAR POLEA 220 4A 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 220 4A and any equivalents.
The EMMAR POLEA 220 4A is a 220 mm diameter pulley with 4 grooves for section A belts, manufactured in-house by MR. It transmits power between parallel shafts in equipment that runs multiple belts, such as compressors, fans, mills, and conveyors. Because it is produced domestically, sizes and groove counts can be adapted to individual machine requirements, and each unit is machined to the tolerances the application demands.
The code POLEA 220 4A packs three key details: outside diameter, groove count, and belt profile. Section A refers to classic narrow-profile belts common in low and medium power industrial drives. With four grooves, the pulley spreads the load across several belts, lowering stress on each and keeping the drive running smoothly.
You will find 4-groove section A pulleys in screw compressors, centrifugal fans, mills, mixers, conveyor belts, and machine tools—equipment where a failed belt should not stop the line. They also serve as replacements for original pulleys on imported machinery when size and groove count align.
When mounting, verify that the shaft diameter and fastening method (keyway, taper bushing, or set screw, as applicable) match your equipment. Drive and driven pulleys must be aligned within usual tolerances to prevent uneven belt wear. For selection, consider power, shaft rpm, and pitch diameter—not just outside diameter. If running four belts, replace them as a set so all share the load equally.

Frequently asked questions
- What does POLEA 220 4A stand for?
- It identifies a pulley with a 220 mm diameter, 4 grooves, and section A. The code condenses size, groove count, and belt profile into one designation.
- Can I order a different diameter or number of grooves?
- Yes. MR makes pulleys in various sizes and groove counts. Send the diameter, groove number, and belt section via WhatsApp, and we will quote the matching variant.
- How do I check if this pulley fits my equipment?
- Match the outside diameter, groove count, belt section, and shaft diameter with bore and keyway. If those agree, it is compatible. If unsure, send a photo of the original part and caliper measurements.
