RS25-2B-32T Duplex Sprocket for Small Chain Conveyor
Part Code: RS25-2B-32T
Part Name: Duplex Sprocket for Small Chain Conveyor
Part Name: Duplex Sprocket for Small Chain Conveyor
Part Code: RS25-2B-32T
Usage: This Sprocket is used in precision chain conveyors requiring double-strand drive for higher torque and synchronized chain motion.
Application of Small Chain Conveyor Sprockets
Built for Compact, High-Precision Motion:
Designed for medium-duty conveyor drives and synchronized transfer systems, this sprocket delivers stable, accurate movement in packaging machines, indexing systems, and compact automation lines.
Optimized for Coordinated Dual-Chain Operation:
The duplex configuration ensures higher torque capacity, reduced slippage, and smooth, balanced motion—ideal for applications requiring reliable, continuous, and fast cycle performance.
Widely Used Across Modern Automation Machinery:
Adopted by packaging automation manufacturers, pharmaceutical and electronics assembly line builders, food handling system designers, and robotic/compact conveyor integrators.
Summary
A durable duplex sprocket engineered for compact conveyor and precision transfer systems, offering stronger torque, smoother dual-chain operation, and long service life in light-to-medium automation environments.
