Tooth Chains

Tooth chains, also known as silent chains or inverted-tooth chains, are used in power transmission applications where smooth, quiet operation and high efficiency are important.
They are commonly found in automotive timing drives, industrial machinery, agricultural equipment, and packaging systems, where precise synchronization and reduced vibration are critical.

Working Mechanism

The tooth-shaped link plates are precision-formed to engage smoothly and transfer power without slipping. They mesh precisely with specially shaped sprockets, much like how gear teeth engage. Without relying on rollers, this design ensures slip-free power transmission with less chordal action, quieter operation, and the ability to run at higher speeds with better efficiency.

Key Advantages

  • Smooth, Silent Operation – Reduced chain link impact delivers quieter running than roller chains and lower noise levels than toothed belts.
  • High-Speed Capability – Operates reliably at high speeds, up to 50 m/s.
  • Low Maintenance – Requires little lubrication and minimal upkeep for long-term performance.
  • Compact & Versatile – Space-saving design with flexible widths and configurations for various applications.
  • Robust in Harsh Conditions – Resistant to high temperatures, heavy loads, and demanding environments.

Common Applications

Rexton tooth chains can be found in power transmission applications where smooth, quiet operation and high efficiency are important.

  • Automotive Assembly Lines – For body transport systems, powertrains, and automated handling.
  • Glassware Manufacturing – Smoothly transferring fragile bottles and containers through hot and cold processes.
  • Package Handling Systems – Reliable transport in high-speed sorting and packaging lines.

Why Choose Rexton® Tooth Chains?

  • Operates quietly, even at high speeds.
  • No pre-tensioning required. this means reduced bearing loads compared to belts that require constant tension.
  • Longer service intervals reduce downtime and operating costs.
  • Suitable for a wide range of industries, from automotive manufacturing to material handling and high-precision machinery.
  • High-performance alternative to conventional roller chains and toothed belts.
