Description
EMMAR POLEA 170 4B 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 170 4B and any equivalents.
The 170 4B pulley is an EMMAR-manufactured V-belt transmission component with a 170 mm diameter, four grooves, and a section B profile. It is designed for industrial machinery that runs multiple belts in parallel, such as fans, compressors, and transmission systems. Because it is made in-house, MR controls the machining and assembly quality.
The part number POLEA 170 4B encodes the key dimensions: 170 mm outer diameter, four grooves, and section B belt profile. The grooves are machined so that section B V-belts seat properly and transfer motion without slipping. This pulley mounts on a shaft and forms part of a belt drive system.
Typical uses for a four-groove section B pulley include industrial fans, screw compressors, centrifugal pumps, conveyors, and machine tools. In these setups, spreading the load across four belts reduces the stress on each individual belt and improves the reliability of the drive. Section B belts are common in industrial applications, so this pulley fits many existing systems.
When selecting or mounting this pulley, consider the shaft diameter, keyway type, and fastening method. Make sure the pulley is aligned with the driven pulley and that belt tension is correct to prevent vibration and premature wear. The four grooves and section B determine how many belts you can install and of what type. For replacement, compare the complete designation and shaft dimensions before ordering.
If you need a different diameter, number of grooves, or section, MR can manufacture custom pulleys or find an equivalent from our power transmission line. To request an equivalent, send the part number POLEA 170 4B or the original pulley data: diameter, grooves, section, and shaft dimensions. We will reply with the best option for your equipment.
To request a quote or ask about a variant, send the part number POLEA 170 4B by WhatsApp or email to MR Industrial Accessories LLC. Our team will provide technical information and help you determine if this pulley is right for your application or if an alternative is better.

Frequently asked questions
- What does the designation POLEA 170 4B indicate?
- It indicates a pulley with a 170 mm diameter, four grooves, and section B. These three data points define the size, number of belts it accepts, and the belt profile. If you have doubts, send us the part number by WhatsApp and we will confirm.
- Which belts are used with this pulley?
- It uses section B V-belts, which seat in its grooves. The four grooves allow up to four belts of that profile. To ensure correct replacement, verify that the belt is section B and that the pulley has the same number of grooves.
- Can I request a pulley with a different size or number of grooves?
- Yes. MR manufactures pulleys and can produce one with a different diameter, number of grooves, or section. Send us the data of the pulley you need or the part number of the current one, and we will quote the option that best suits your equipment.
