GL type roller chain coupling AUTOCAD rendering (GB6069-2002 replaces GB6069-86) features: The chain coupling uses a common chain and meshes with two parallel sprockets with the same number of teeth. The main difference between different structural types of chain couplings is the use of different chains, commonly including double row roller chain couplings, single row roller chain couplings, toothed chain couplings, nylon chain couplings, etc. The performance of the double row roller chain coupling is superior to other structural types of couplings, and it is widely used both domestically and internationally. China has also established it as a standard.
