The EMMAR 310 4B pulley is a V-belt drive component with a 310 mm diameter and four grooves for section B belts. It transfers power between parallel shafts in industrial machinery where a specific transmission ratio and multiple belts are needed. Because EMMAR manufactures it in-house, machining and balancing can be adapted to the application.
This pulley has a 310 mm outer diameter, four grooves, and takes section B belts. Section B is a classic V-belt profile, and the four grooves let you run up to four belts side by side on the same pulley. The 310 mm diameter sets the transmission ratio when paired with another pulley of the same type. The part is cast iron or machined steel with ground grooves so belts seat evenly and wear is reduced.
You will find it in power transmissions on machine tools, compressors, fans, pumps, conveyor belts, and process equipment. It also shows up in agro-industrial settings and maintenance shops that replace worn pulleys or change the transmission ratio. With four grooves, it can handle relatively high torques with section B belts, as long as the drive calculation confirms it.
When selecting a pulley like this, check the pitch diameter, number of grooves, belt section, and the bushing or bore type. Shaft speed, power to transmit, and pulley alignment also matter. During installation, verify concentricity, belt tension, and groove condition. If the pulley mounts on a keyed shaft, respect the fit tolerances.
For an equivalent pulley, send the part number, number of grooves, and belt section. It also helps to include the current diameter, bore type, and a photo of the part. With that information we can point you to a pulley with similar characteristics or manufacture one. We handle standard sizes and custom developments within our power transmission line.

Frequently asked questions
- What does section B mean?
- Section B is a classic V-belt profile. The pulley has grooves machined for that profile, so you must use section B belts. It is not compatible with other belt sections without changing the pulley.
- Can I order it with a different bore or keyway?
- Yes, because it is manufactured in-house, machining can be adapted to your shaft. Send the shaft dimensions, fit type, and whether it has a keyway. We will confirm feasibility and provide a quote.
- How do I know if it replaces my current pulley?
- Compare diameter, number of grooves, and belt section. If they match, it is likely equivalent. Still, verify the pitch diameter and mounting type. Send that data by WhatsApp and we will review it.
