Description
EMMAR POLEA 90 1A 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 1A and any equivalents.
The POLEA 90 1A is a single-groove V-belt pulley with a 90 mm pitch diameter, designed for section A belts. Manufactured by EMMAR, it is used to transmit motion between parallel shafts in industrial machinery where a simple, dependable ratio is required. The in-house production allows control over machining and balancing, so the belt seats properly and the assembly runs smoothly.
With one groove and a section A profile, this pulley suits single-strand drives using classic narrow V-belts. The 90 mm dimension is the pitch diameter, and the groove is machined so the belt contacts the flanks rather than the bottom. Depending on the batch, it is made from cast iron or steel, with dimensional checks performed during manufacturing.
Typical applications include fans, pumps, compressors, conveyors, mixers and machine tools, as well as air conditioning systems and low to medium power transmissions. Its compact size fits tight spaces where a larger diameter pulley would not. A single groove is selected when the power requirement does not call for multiple strands.
For installation, confirm the shaft diameter and tolerance and that the keyway matches. Align the pulley with the drive pulley to prevent uneven belt wear. Adjust tension according to the equipment manual or standard practice: too loose causes slipping, too tight stresses the bearings. When replacing an existing pulley, note the pitch diameter, number of grooves and section as the minimum data for an equivalent.
If you need a different diameter or additional grooves, provide the original pulley data: diameter, section, number of grooves and shaft diameter. We can then source or manufacture the equivalent part. We also assist if the pulley mounts with a taper bushing or directly on the shaft, so you can confirm fit and performance before ordering.

Frequently asked questions
- What does section A mean for this pulley?
- Section A is a standardized V-belt profile. The groove angle and dimensions are designed for that belt type. It is not interchangeable with other belt sections without changing the pulley.
- Can I get a 90 mm pulley with more than one groove?
- Yes. If you need more than one groove to transmit more power, a pulley of the same diameter and section with two, three or more grooves can be manufactured or sourced. Send the measurements and we will quote the variant.
- How do I know if the pulley fits my shaft?
- You need the shaft diameter and the type of fit (with keyway, with taper bushing, etc.). The 90 mm pulley is made with different bores depending on the shaft. Send us that data and we will confirm the combination.
