Description
Robust Material: The roller chain idler sprocket is made of 1045 steel, heat-treated for high hardness and wear resistance. The blackened surface treatment provides rust and corrosion resistance, ensuring durability.
Precision Design: The idler sprocket features a boss design to ensure stable installation and chain alignment. Internally, it incorporates sealed bearings for smooth rotation and low resistance. Each roller chain idler has strong teeth that engage with the chain, effectively guiding and tensioning it.
Easy Installation: Before installation, ensure the shaft diameter and chain specifications match, ensuring at least three teeth on the sprocket are engaged with the chain. During use, the idler sprocket's speed should not exceed the permissible speed of the drive sprocket of the same size.
Wide Applications: The C-type idler sprocket is commonly used for chain guidance and tensioning in machinery. Suitable for chain drive systems in go-karts, ATVs, off-road motorcycles, mini bicycles, wood splitters, and other equipment, widely used in milling machines, drilling machine or other machinery transmission occasions.
