The 340 1B pulley is an in-house manufactured power transmission pulley, EMMAR Accesorios Industriales brand. It is designed to mount a section B V-belt and transmit motion between shafts. Its 340 mm diameter and single groove make it suitable for applications requiring a specific transmission ratio with a single belt. It is machined in our own factory, which allows dimensions and finish to be controlled. It is a key part in belt drive systems.
This pulley has a 340 mm diameter, 1 groove and section B. The designation POLEA 340 1B summarizes these characteristics: the number indicates the measurement in millimeters and 1B the number of grooves and the belt section. It is manufactured by EMMAR, so its geometry and balancing meet the house standards. The groove is machined to seat section B belts, ensuring uniform contact and efficient transmission.
It is used in industrial machines, compressors, fans, pumps and transmission equipment that use V-belts. It is common in installations where speed needs to be reduced or increased between a motor and a driven shaft. It is also used in production lines and agricultural equipment. Its robust construction makes it suitable for continuous service in demanding environments.
To select this pulley, verify that the belt is section B and that the pitch diameter matches the desired transmission ratio. It is important to check the alignment between pulleys and the belt tension to avoid premature wear. Mounting must be done on a shaft with the appropriate tolerance and with the corresponding fastening elements. If you need a different number of grooves or diameter, contact us.
