The 130 3B pulley is a V-belt drive pulley made by EMMAR. It measures 130 mm in diameter, has 3 grooves and uses section B. This configuration lets you run several belts side by side to transfer power in industrial equipment. It suits machines, compressors, fans and drive systems where space is limited but drive capacity matters. Since EMMAR manufactures it in-house, you can request machining variations to match your setup.
With a 130 mm diameter, 3 grooves and section B, this pulley sits in the small-to-medium range of the section B line. Section B refers to the V-belt profile, and the three grooves accept three B-section belts mounted in parallel. The pulley mounts on a shaft and transmits motion from a motor to another part of the system.
Common uses for a 3-groove section B pulley include screw compressors, centrifugal fans, pumps, conveyor belts and machine tools. Running multiple belts spreads the load and reduces wear on each belt. In some setups, the extra belts also provide a degree of redundancy: if one belt fails, the remaining two can keep the drive running until you replace it.
When selecting this pulley, check the pitch diameter, number of grooves and belt section. Section B requires a matching B-profile belt; do not mix sections. Confirm that the shaft diameter and keyway are correct, and that the fastening method—set screw, taper bushing or plate—fits your application. Proper alignment between pulleys helps prevent uneven belt wear and vibration.
For an equivalent pulley, send the part number POLEA 130 3B by WhatsApp. You can also tell us the diameter, number of grooves and section you need, and we will quote the best match. Because EMMAR manufactures this pulley in-house, we can evaluate machining variants such as different shaft diameters or fastening types based on where it will be installed.

Frequently asked questions
- What does section B mean for this pulley?
- Section B is a standard V-belt profile. The grooves on this pulley are cut for that geometry, so it only accepts section B belts. It is not compatible with section A, C or other belt types.
- Can I run this pulley with fewer than three belts?
- Yes, you can use one or two belts if your drive calculation allows it. However, the usual practice is to use all three grooves to distribute the load. If you use fewer, make sure the belt sits properly in the groove.
- How do I ask for a different shaft diameter?
- Send the part number POLEA 130 3B by WhatsApp and specify the shaft diameter you need. Since EMMAR manufactures it in-house, we can evaluate machining the bore and keyway to your requirement.
