The 450 4B pulley is a V-belt drive pulley manufactured by EMMAR Accesorios Industriales. It has a 450 mm diameter, 4 grooves and section B. It is used to transmit power between parallel shafts in industrial equipment, with the advantage that, since it is in-house manufacturing, we can adjust the machining to whatever your assembly needs. If you are building or replacing a drive, this pulley lets you work with four section B belts in a single body.

This item is a pulley with a 450 mm diameter, 4 grooves and section B. The designation POLEA 450 4B summarizes those three variables: the outside diameter, the number of grooves and the belt profile. Section B corresponds to classic-type V-belts, and the four grooves allow the load to be distributed among several belts. Since it is in-house manufacturing, EMMAR brand, the machining is done in our factory, which makes it easier to replace an existing pulley or adapt the bore and keyway to your shaft.

Typical applications for a 450 mm, 4-groove section B pulley are in medium- and high-power drives: industrial fans, centrifugal pumps, compressors, mills, mixers and conveyors. It is also used in woodworking machines, crushers and process equipment where revolutions need to be reduced or increased between a motor and the working shaft. With four grooves, it is a common choice when the goal is to spread the load and reduce vibration from an individual belt.

To mount and select this pulley, take into account the shaft diameter, the type of keyway and the fastening system. Check that the belt section matches groove B and that the number of grooves is the same on the driving and driven pulleys. Check the alignment between pulleys with a straightedge or laser: misalignment accelerates belt and bearing wear. If the pulley is going to run at high revolutions, balancing should be evaluated. For mounting, use suitable tools and avoid striking the edge of the grooves.

If you need a nearby size, a different diameter or a pulley with a different number of grooves, it can be manufactured. To request an equivalent or a variant, send us the part number POLEA 450 4B together with the shaft diameter, groove width, number of grooves and a photo or sketch of the original pulley. With that data we can confirm the part or propose an alternative from our in-house manufacturing line. We can also guide you if you are unsure between section B and another section.
