A roller chain coupling is mechanical equipment composed of a double-strand roller chain and two forged, extended, hardened sprockets.
Cast Aluminium Covers
For more demanding applications, cast aluminium covers extend life of couplings by providing continuous lubrication and full protection from abrasive elements. The two halves fit around the coupling and connect by ‘Nyloc’ cap-head bolts. Neoprene seals are fitted to seal between sprocket hub and cover. These covers are fitted after coupling is fully installed on shafts.
The design is simple and highly effective. Despite chain couplers small size, it is composed of a robust chain and specially cut and hardened-tooth sprockets that permit a high amount of torque to be transmitted.
Each of these components of chain couplers are manufactured and assembled to precise tolerances and heat treated to optimize performance with regard to wear resistance, fatigue strength, and tensile strength of chain couplers.
