The 500 7B pulley is a V-belt drive pulley, manufactured by EMMAR Accesorios Industriales. It has 500 mm diameter, 7 grooves and section B. It is used to transmit power from a motor to a driven shaft, maintaining the transmission ratio and parallelism between pulleys. It is a key part in machines that work with continuous loads and require stable operation.
This pulley has 500 mm diameter, 7 grooves and section B. Section B corresponds to classic-profile V-belts, and the 7 grooves allow mounting several belts in parallel to distribute the load. The 500 mm diameter defines the transmission ratio together with the driving pulley. It is an in-house manufactured pulley, EMMAR brand, designed for applications requiring robustness and precise alignment.
It is used in drives of industrial machines: compressors, fans, pumps, mills, conveyor belts and process equipment. Also in the field, in agricultural machines and implements that work with section B belts. It is commonly found in installations where the driven shaft speed needs to be reduced or increased relative to the motor.
To mount it, check that the shaft and keyway are clean and free of burrs. The pulley must fit with a tolerance that does not allow radial or axial play. Check the alignment with the driving pulley using a straightedge or a laser; misalignment accelerates belt and bearing wear. Tension the belts according to the belt manufacturer's manual and check parallelism before starting up.
If you need a pulley with a different number of grooves, a different diameter or for another belt section, send us the part number or the size marked on the part. We can also evaluate a replacement if you send us the shaft, keyway and original pulley dimensions. We work with standard sizes and custom manufacturing as needed.

Frequently Asked Questions
- What does section B mean on a pulley?
- Section B is a classic V-belt profile. It defines the width and depth of the groove where the belt rests. Section B pulleys are used with belts of that profile, and are not interchangeable with belts of other sections such as A, C or 5V.
- Can I change a 6-groove pulley for a 7-groove one?
- Yes, as long as the diameter and shaft bore match. A 7-groove pulley allows mounting more belts and distributing the load better. Check that the total width of the pulley fits in the available space and that alignment with the driving pulley is maintained.
- How do I request a pulley with a different shaft size?
- Send us by WhatsApp the shaft diameter, the keyway width and the number of grooves you need. With that data we check whether there is a standard pulley or whether it is better to manufacture it custom. We can also copy the dimensions of the original pulley.
