Description
# Idler Sprockets
Idlers are used to take-up extra belt length and provide adjustment for tensioning belt drives. Idler pulleys and sprockets can alter belt paths and clear obstructions.
- Idler assembly may consist of: idler sprocket and bracket, flat idler and bracket, standard sheave or sprocket used with an idler bearing and idler bracket.
- Idler sprockets, flat idlers and idler bushings contain sealed ball bearings and an integral shaft for mounting to adjustable idler brackets.
- Lubrication and maintenance are not required.
## Flexible Drive Design
Gates® Idler Sprockets can be integral belt drive components, providing drive designers with added versatility in creating drive solutions. When specific operational challenges present themselves, Idler Sprockets can be used to alter belt paths and navigate machinery obstructions, without sacrificing drive performance. To provide even more assistance to drive designers, Gates offers application engineering assistance and tools, such as our Partview system.
## Multi-Belt Compatible
Gates® Idler Sprockets are available in a range of sizes and material composition, making them compatible with Poly Chain® GT™ belts, Poly Chain®, Poly Chain® GT™, Carbon belts, and Powergrip GT™ belts.
