BK Series Cast Pulleys
A cast pulley is a type of pulley that is made by casting metal into a mold. The mold is made of two parts, one for the hub and one for the rim. The metal is poured into the mold and allowed to cool and solidify. The two parts of the mold are then separated, and the pulley is removed.
In the realm of power transmission, cast pulleys play a crucial role in ensuring smooth and efficient operation. Designed for heavy-duty applications, cast pulleys offer exceptional durability and reliability.
