Needle Bearing Idler Sprockets

An idler sprocket is a critical component in conveyor systems, responsible for maintaining tension in the chain and guiding it around bends and corners. It plays a crucial role in ensuring the smooth and efficient operation of the conveyor system.

Idler sprockets are designed to work with conveyor chains, which are used to move materials from one location to another. They are typically made from high-quality materials, such as steel or cast iron, and are highly resistant to wear and tear. Idler sprockets come in a variety of sizes and tooth configurations, depending on the specific application.

Our needle bearing idler sprockets are manufactured using high quality bearings and quality sprockets. Usually this style of idler sprocket is used in high-speed applications due to the reduced amount of friction and increased stability.

Characteristics Of Idler Sprocket:

Idler sprockets have several characteristics that make them ideal for use in conveyor systems. These include:

High strength and durability: Idler sprockets are made from high-quality materials, such as steel or cast iron, and are highly resistant to wear and tear, making them ideal for use in harsh industrial environments.

Precision tooth profile: The teeth on idler sprockets are precisely machined to ensure a perfect fit with the conveyor chain, reducing wear and tear and increasing the efficiency of the conveyor system.

Corrosion resistance: Idler sprockets are highly resistant to corrosion, which makes them ideal for use in outdoor applications or in environments with high humidity.

Wide temperature range: Idler sprockets can operate in a wide range of temperatures, making them ideal for use in both hot and cold environments.
