The 170 5B pulley is a power transmission pulley, in-house manufactured, EMMAR Accesorios Industriales brand, with a 170 mm diameter and 5 grooves for section B belts. It is used to transmit motion between parallel shafts in industrial equipment, where speed must be multiplied or reduced and the load distributed among several grooves. Its construction allows it to be mounted on shafts with a keyway and secured with set screws or taper bushings, depending on the equipment.

This item is a pulley with a 170 mm diameter, 5 grooves and section B. The designation POLEA 170 5B summarizes those three variables: the 170 mm outer diameter, the number of grooves (5) and the belt profile it accepts, section B. Because it is in-house manufactured, EMMAR brand, the groove machining and balancing are controlled so the pulley turns without vibration at the usual speeds of belt transmission. It is supplied with the bore to be defined according to the equipment shaft.

Typical applications of a 5-groove section B pulley appear in power transmissions of industrial machines: compressors, fans, centrifugal pumps, mills, mixers and conveyors. In those machines, the driving or driven pulley receives several belts to distribute the load and reduce slippage. It is also used in agricultural machinery and in plant equipment where an existing pulley is replaced due to wear or a change in transmission ratio.

To select and mount this pulley, take into account the shaft diameter, the type of fastening (keyway, set screw or taper bushing), the center distance and the desired transmission ratio. Verify that the grooves are aligned with those of the opposite pulley and that belt tension is correct: a misaligned pulley accelerates wear on the groove and the belt. If the equipment works with variable loads, it is advisable to check balancing and fastening before start-up.
