The EMMAR 280 8C is a V-belt pulley with a 280 mm diameter and eight grooves for section C belts. It is manufactured in-house, which means the bore, keyway and balance can be tailored to the drive. Use it to set shaft speed on belt-driven equipment, either as the driving or driven sheave. When you need to replace a worn pulley or assemble a new drive, this model handles multiple belts running in parallel.

On this pulley, the eight grooves are the seats that carry the V-belts, and section C is the belt profile they accept. With eight seats, the drive can share the load across several belts, which is typical when the power demand is high or when some redundancy is useful. The 280 mm diameter, together with the pulley it runs against, determines the speed ratio of the drive. It is an EMMAR-manufactured item, not a resale part, so the dimensions and finish follow the application.

You will find this size on belt-driven machines such as compressors, fans, pumps, mills, conveyors, mixers and other process equipment. It also appears on agricultural implements and field machinery that use section C pulleys. With eight grooves, it often sits on the high-speed shaft driving a slower, higher-torque shaft, or the reverse, depending on how the pair is arranged.

Before mounting, confirm that the bore and keyway match the shaft, and that the pulley lines up with its counterpart. Even a small misalignment puts extra stress on belts and bearings. The number of belts you install depends on the power to be transmitted; not all eight grooves must be used if the calculation calls for fewer, but the belts that are mounted should run at matched tension. Inspect the grooves for burrs or wear before installation, since damage there affects how the belt seats.

If you need a different diameter, another groove count or a pulley for a different belt type, it can be ordered. The same applies if you are matching a pulley already in service: provide the outside diameter, number of grooves, belt section and bore diameter, and we can compare it with what we manufacture. Material and treatment can also be reviewed for the working environment.

If you are unsure about equivalence with the pulley you are replacing, send a photo or the shaft dimensions and we will help you identify it. We can also assist with the belts and bearings on the same equipment.
