Description
EMMAR POLEA 210 3A 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 210 3A and any equivalents.
The 210 3A is a V-belt drive pulley from EMMAR. It measures 210 mm in diameter and has three grooves for section A belts. It transmits motion between parallel shafts in industrial machinery where a fixed ratio is required and can be adjusted by changing the groove count or diameter. Because it is made in-house, the bore and keyway can be machined to match your shaft.
The part number POLEA 210 3A encodes the three key variables: outside diameter (210 mm), number of grooves (3), and belt profile (section A). Section A refers to classic narrow-profile V-belts, which transmit power in compact spaces. As an EMMAR in-house manufactured item, the center bore and keyway are machined on demand to fit the shaft where it will be installed.
Typical applications include compressors, fans, centrifugal pumps, conveyor belts, mixers, and machine tools—any equipment that needs to transfer motion between separate shafts. You will also find it in air conditioning systems and low-to-medium power drives. With three grooves, it can run up to three section A belts in parallel, spreading the load and allowing you to adjust transmitted power to match demand.
When selecting a pulley like this, check the pitch diameter, groove count, belt section, and shaft diameter. The pulley mounts on the shaft with a keyway and is secured axially with a set screw or other suitable fastener. Proper alignment between pulleys is critical to prevent uneven belt wear and vibration. Tension the belts according to the equipment manual or the belt manufacturer's recommendations.
If you need a different groove count, diameter, or section, an equivalent can be requested. Send the part number POLEA 210 3A along with shaft details: diameter, bore length, and keyway type. Also include the belt you plan to use and the center distance. With that information, we can evaluate manufacturing or adapting a similar pulley.
To request a quote or ask about a variant, send POLEA 210 3A by WhatsApp. If you are unsure about the section, number of grooves, or bore machining, message us with your equipment data and we will help you specify the correct pulley.

Frequently asked questions
- What does in-house manufactured, EMMAR brand mean?
- It means the pulley is produced in our own workshops. That allows the center bore, keyway, and other dimensions to be adapted to the shaft where it will be mounted, within machining capabilities.
- Can I request a pulley with a different number of grooves or diameter?
- Yes. You can ask about a section A pulley with another diameter or more/fewer grooves. Just send the current part number and the shaft and belt data you plan to use.
- How do I know if section A is correct for my equipment?
- The belt section is determined by the equipment design. If you have a belt mounted, check the profile marked on the back. If not, contact us with the drive data and we will help you identify it.
