Chain Idler Sprockets – 5/8" Pitch | Reliable Chain Tension Solutions

Do you need high quality idler sprockets for a roller chain drive system? Here at BEP Ltd, we supply a high-quality selection of chain idlers which are suitable for maintaining your slack, equipment, increasing tension and creating a more fluid and efficient movement across all mechanical systems.

Our 5/8" pitch idler sprockets are a quality product and are manufactured to ANSI specifications to ensure that your sprocket will provide many years of trouble-free operation in any application like the agricultural, packaging, wood products, and material handling industry.

Why Use an Idler Sprocket?

An idler sprocket is an essential part of chain drives. Mounted on fixed or telescopic shaft, it helps to:

• Maintain proper chain tension
• Guide chain routing in complex systems
• Reduce chain vibration, wear, and noise
• Prevent sag in long chain spans

Whether you are constructing an entirely new machine or you are simply repairing existing equipment, chain idlers ensure that your setup will last longer and operate more reliably.
