Double Plus Sprocket Manufacturer - Shreeji Gears

Precision Double Plus Sprockets

Shreeji Gears is a specialized double plus sprocket manufacturer, producing sprockets designed to work with Double Plus® (free-flow) roller chains. These chains feature large diameter top rollers that allow products to accumulate while the chain moves beneath.

Our Double Plus sprockets have a unique tooth profile that engages only the smaller chain rollers. This is crucial for accumulation conveyor systems requiring smooth, low-friction product transfer.

Understanding Double Plus Sprockets

Double Plus sprockets are engineered for a specific type of free-flow conveyor chain. This chain design incorporates two roller sizes: smaller inner rollers that carry the chain tension and larger outer rollers that support the conveyed product.

Key Characteristics & Function:

  • Specialized Tooth Profile: The sprocket teeth are designed to mesh only with the smaller, inner load-carrying rollers.
  • Free-Rotating Top Rollers: The design ensures that the large top rollers do not contact the sprocket teeth, allowing them to rotate freely.
  • Accumulation Capability: This free rotation enables products on a conveyor to stop (accumulate) against a barrier while the chain continues to run underneath without excessive friction.
  • Smooth Product Transfer: The large, free-rolling top surface provides a smooth platform for moving goods.

Applications:

Double Plus sprockets are primarily used in accumulation conveyor systems found in automotive assembly, electronics manufacturing, logistics, warehousing, and packaging lines.
