Description
EMMAR POLEA 90 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 90 3A and any equivalents.
The 90 3A pulley is a V-belt drive component with a 90 mm diameter and three grooves for section A belts. It is used to transmit power between parallel shafts where a fixed speed ratio and reliable belt grip are required. This pulley is manufactured in-house under the EMMAR brand, which means you can request variations in diameter or groove count within the same belt section.
The part number 90 3A tells you the key specifications: 90 mm diameter, 3 grooves, and section A profile. Section A refers to classic narrow V-belts, which are suitable for power transmission in compact spaces. Because it is an in-house EMMAR product, you can ask about other diameters or groove numbers in section A to match your specific drive requirements.
Typical uses include compressors, fans, centrifugal pumps, conveyor belts, and other factory equipment with belt drives. It is also found in speed reducers and multipliers where a stable output speed must be maintained. With three grooves, the load is distributed across multiple belts, reducing stress on each belt and improving drive continuity.
When mounting a 90 3A pulley, first check the shaft diameter and the fastening method—keyway, set screw, or taper bushing. Make sure the pulley is aligned with the drive pulley; angular or parallel misalignment will accelerate wear on both the belt and the equipment bearings. Adjust belt tension according to the machine manufacturer's manual: too much tension strains the supports, while too little causes slippage.
If you need an equivalent pulley, the easiest way is to send the part number 90 3A to our team via WhatsApp or email. You can also provide the outside diameter, number of grooves, belt section, and shaft diameter. With that information, we will help you find the pulley that best fits your application, whether it is section A or another section if your equipment requires it.
In addition to pulleys, we manufacture split plummer block housings and ANSI chains, and we supply bearings, power transmission components, seals, bushings, mounting tools, and lubricants. If you have questions about the 90 3A pulley or need a different size, contact us with the part number and we will respond with a quote.

Frequently asked questions
- What does the designation 90 3A indicate?
- It indicates a pulley with a 90 mm diameter, 3 grooves, and section A profile. This tells you the size, number of grooves, and the belt type it accepts. If you need a different combination, you can request a pulley from the same section with another diameter or groove count.
- How can I request an equivalent pulley?
- Send the part number 90 3A via WhatsApp or email, and if possible include the shaft diameter, belt section, and number of grooves you need. With that information, we will look for the pulley that best suits your equipment, whether it is an in-house EMMAR product or another line we supply.
- What should I consider when mounting this pulley?
- Check the shaft diameter and fastening method, align the pulley with the drive pulley, and set belt tension according to the machine manual. Misalignment or incorrect tension will accelerate wear on the belt and bearings.
