The EMMAR 450 6B is a V-belt drive pulley with a 450 mm diameter, six grooves, and a section B profile. It is produced in-house by EMMAR, which allows control over dimensions and balancing. This pulley transfers power between parallel shafts, and the combination of its diameter with another pulley sets the speed ratio.

With a 450 mm outer diameter and six grooves, this pulley accepts classic section B V-belts. That profile is intended for medium power and moderate belt speeds. Distributing the drive across six belts raises the torque the unit can carry and adds a margin: if one belt breaks, the remaining belts continue to transmit until a replacement is fitted. The 450 mm diameter is the figure you use when calculating the ratio against the mating pulley.

Typical installations include screw compressors, industrial fans, mills, mixers, conveyor drives, and pumping equipment—machines where the shafts sit some distance apart. In agricultural work, combine harvesters and implements running section B belts also use this size. Six grooves suit jobs that call for high torque without moving up to a larger belt section.

During mounting, confirm the shaft diameter and key match the pulley bore. Use a straightedge or laser to align the pulleys; misalignment causes uneven belt and bearing wear. Set belt tension by the equipment manual or with a tension gauge—loose belts slip, while overtight belts load the bearings. Make sure every groove is clean and free of burrs. For a taper bushing mount, tighten the screws to the torque specified by the bushing manufacturer.

To match an existing pulley, send the full code or the current dimensions: diameter, groove count, and section. Where space permits, a custom pulley can be produced, and because manufacturing is in-house, the bore, keyway, or mounting style can be adapted to your shaft. Send the details via WhatsApp and the 450 6B or the variant you need can be quoted.

EMMAR makes this pulley with dimensional checks and balancing. If compatibility with your equipment is unclear, send the code via WhatsApp for guidance. A complete assembly with section B belts and bushings can also be quoted.
