The 90 mm industrial pulley with 2 grooves for section A belts is a power transmission component that mounts on shafts to drive machines through V-belts. MR manufactures it in its own workshops, with dimensional control and balancing, so the belt seats evenly and the equipment runs without vibration. It is used in fans, compressors, pumps and conveyors, where torque must be transmitted with a stable transmission ratio.

This item is a pulley with a 90 mm diameter, 2 grooves and section A. Those three data points define the mounting: the 90 mm outside diameter, the number of grooves where the belts rest and the belt section it corresponds to, in this case A. The part is machined and the pitch diameter and groove width are verified so the belt does not slip or wear excessively. Since it is in-house manufacturing, EMMAR brand, you can ask about variants within the same section.

Typical applications are equipment that needs to transmit motion between a motor and a mechanism: centrifugal fans, screw compressors, centrifugal pumps, belt conveyors and machine tools. In all those cases, the 2-groove pulley allows the load to be distributed between two belts, which reduces the tension on each one and extends the service life of the assembly. It is also used to correct the transmission ratio when the motor does not have the exact speed the machine requires.

To mount and select this pulley, take into account the shaft diameter, the type of keyway and the fastening system. Verify that the belt section matches section A and that the number of grooves is the one needed for the power to be transmitted. Alignment between pulleys is key: a misalignment of a few degrees accelerates wear on the belt and on the shaft bearings. If the equipment works with variable loads, it is advisable to check the tensioner and the center distance.

If you need an equivalent pulley or a nearby size, send us the full part number or the designation shown on the part. With that data we can search the in-house manufacturing line for a pulley with a different diameter, number of grooves or section. We can also quote a custom pulley if the shaft or keyway do not match the standard. The more data you send us — shaft diameter, belt section, number of grooves — the faster we respond.
