12022 PILOT BORE CHAIN COUPLING

High-Torque Performance & Maximum Durability

The 12022 Pilot Bore Chain Coupling is a robust, all-metallic power transmission solution designed for heavy-duty industrial environments. Engineered with two precision-machined sprockets joined by a rugged Duplex Chain, this coupling delivers superior strength and a significantly higher torque capacity than standard elastomeric alternatives.

Featuring induction-hardened teeth for maximum wear resistance, its compact design allows you to handle exceptional torque loads even within tight spatial constraints.

Key Benefits & Features

  • Built for Strength: All-metallic construction with hardened sprocket teeth ensures extra durability and an extended operational lifespan.
  • Space-Saving Efficiency: High torque density means smaller, more compact couplings can be selected because the torque capacity exceeds the normal torque transmitted by the largest shaft size.
  • Effortless Maintenance: Both drive and driven shafts can be coupled or uncoupled simply by detaching a single chain link. This allows for quick inspections, easy maintenance, and independent drive rotation checks without risking damage to your driven equipment.
  • Premium Housing Protection: The coupling is protected with a split Aluminium Casing fitted with high-quality seals and gaskets. It retains crucial lubrication to extend coupling life while keeping contaminants out—just undo the cap heads on either side for instant access to the duplex chain.
