Bearing Mounted Idler Sprocket Manufacturer - Shreeji Gears

Precision Idler Sprockets

Shreeji Gears is a leading idler sprocket manufacturer, producing specialized sprockets designed to manage and optimize roller chain drives. Unlike drive sprockets, idlers serve crucial functions like chain tensioning and chain guiding.

Equipped with integrated ball bearings, our idler sprockets are essential for taking up slack, routing the chain path, or increasing chain wrap on drive sprockets, improving drive performance and longevity.

Understanding Idler Sprockets

Idler sprockets play a supportive role in roller chain drives. They are placed within the chain path but do not transmit power, instead enhancing the function and lifespan of the entire system.

Primary Functions:

  • Chain Tensioning: The most common use. Idlers take up slack in the chain as it wears, ensuring proper engagement and preventing chain skipping.
  • Chain Guiding: Used to route the chain around obstructions or to maintain a specific path.
  • Increasing Chain Wrap: Can be positioned to increase the angle of wrap around a small drive sprocket, improving power transmission.
  • Supporting Long Chains: On long conveyors, idlers can support the weight of the chain, preventing excessive sag.

Key Features:

  • Integrated Bearings: Most idlers incorporate ball bearings (often sealed or shielded) allowing them to rotate freely with minimal friction.
  • Matching Pitch: Must have the same pitch and profile as the roller chain and other sprockets in the drive.

Advantages of Using Idlers:

  • Extended Chain & Sprocket Life: Proper tension reduces wear.
  • Smoother, Quieter Operation: Reduces chain vibration and noise.
  • Prevents Chain Skipping: Maintains correct engagement under changing loads.
