The 500 7B pulley is a V-belt drive pulley manufactured by EMMAR Accesorios Industriales. It has a 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 component in machines that work with continuous loads and require stable operation.
This pulley has a 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 drive pulley. It is an in-house manufactured pulley, EMMAR brand, designed for applications requiring robustness and precise alignment.
It is used in industrial machine drives: 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 speed of the driven shaft needs to be reduced or increased relative to the motor.
For mounting, verify 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 alignment with the drive pulley using a straightedge or 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, another diameter or for another belt section, send us the part number or the measurement marked on the part. We can also evaluate a replacement if you provide the shaft dimensions, keyway and original pulley. 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 sits. 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 replace a 6-groove pulley with a 7-groove one?
- Yes, as long as the diameter and shaft bore match. A 7-groove pulley allows mounting more belts and better distributing the load. Verify that the total width of the pulley fits in the available space and that alignment with the drive pulley is maintained.
- How do I order a pulley with a different shaft size?
- Send us the shaft diameter, keyway width and number of grooves you need via WhatsApp. With that data we will propose the corresponding standard pulley or manufacture it to measure. We can also copy the dimensions of the original pulley.
