Products Description

A chain sprocket is an essential component of power transmission machinery. It’s used to transfer torque from a driving shaft to a driven shaft through a roller chain. The European Standard chain sprockets (12B 16B 20B) are the most commonly used styles in the industry. The 12B 16B 20B European Standard Chain Sprockets are available in different materials such as 45 steel, stainless steel and cast iron.45 steel sprockets are the most commonly used due to their excellent strength and durability. Stainless steel sprockets are suitable for applications in environments with high corrosion and high temperature conditions, like food and beverage processing plants. Cast iron sprockets are best used for heavy load applications like conveyor systems.

There are different types of 12B 16B 20B European Standard Chain Sprockets, including simplex, duplex, and triplex. Simplex sprockets have only one row of teeth, and they’re used in applications with low to moderate loads. Duplex sprockets have two rows of teeth, and they’re used in applications with heavier loads. Triplex sprockets have three rows of teeth, and they’re used in applications with the heaviest loads.
