四川 Shanxi, Shaanxi and Shandong chain coupling production plant in Zhengzhou Fest coupling chain coupling is the use of common chain, while the same number of teeth in parallel with the two different structural types sprocket engages the chain couplings main difference is the use of a different chain, a common double roller chain coupling, single-row roller chain couplings, silent chain couplings, nylon chain couplings. Double roller chain coupling properties superior to other types of coupling structures, widely used at home and abroad, our country has formulated a national standard. Chain coupling has a simple structure (four pieces of composition), easy assembly and disassembly, disassembly without moving the two shafts are connected, compact size, light weight, have a certain ability to compensate for installation less precision, reliable, life long, and low cost.
