The 150 4A pulley is a V-belt transmission pulley, manufactured by EMMAR Accesorios Industriales. It has a 150 mm diameter and 4 grooves for section A belts. It is used to transmit motion between parallel shafts in industrial machines and equipment, where speed must be increased or reduced and the load distributed among several belts. Being of in-house manufacturing, dimensions and balancing are controlled for even operation.

This pulley has a 150 mm outside diameter and 4 grooves for section A belts. Section A corresponds to classic narrow-profile V-belts, suitable for medium power and moderate speed transmissions. The 4 grooves allow the load to be distributed among four belts, which increases transmission capacity and provides margin if one belt fails. The grooves are machined so that the belt seats uniformly and does not deform.

It is used in compressors, fans, pumps, mills, mixers and transmission lines in general. Also in agricultural and industrial machines that already have section A belts. It is common in equipment where the speed ratio between a motor and a working shaft needs to be changed, or where power is to be transmitted to several shafts at once. Due to its diameter, it is suitable for moderate transmission ratios.

To choose it correctly, take into account the diameter of the drive and driven pulleys, the power to be transmitted, the rpm of the faster shaft and the center distance. The number of grooves is defined according to the power and the belt type. During mounting, verify that the keyway and shaft are clean, align the pulleys with a straightedge or laser and tension the belts according to the manufacturer's manual. Misalignment or incorrect tension shortens the life of the belts and bearings.

If you need a pulley with a different number of grooves, a different diameter or for section B, C or SP belts, we can manufacture it. We can also quote a pulley equivalent to the one you are using, if you send us the part number or the shaft and keyway measurements. We work with in-house manufacturing, so we adapt the machining to what you need. Ask us about special sizes or batches.
