A s lip-fitted couple pin allows for easy assembly and disassembly. The Nylon Chain Coupling is ideal for application in the food and textile industries.  \nSimple Flexible  \nLube Free  \nRoller Chain Couplings  \n■ Features  \nOutstanding Durability  \nThe coupling performs outstanding durability with the torque on the coupling shared with the surfacehardened teeth of the sprockets and the powerful roller chains that engage with the teeth.  \nEasy Coupling and Decoupling  \nBoth shafts can be easily coupled or decoupled with a single joint pin inserted into or extracted from the roller chains.  \nAbsorption of Large Misalignment The clearances between the chains and sprocketsand between chain components absorb the great positional misalignment of both shafts.  \nModels in a Wide Variety  \nA total of 24 models including 15 models conforming to JIS and 9 other models are standardized.  \n(Roller chain shaft joint: Conform s to JIS B 1456-1989)  \n● Fit Bore Series ̶See page 7̶  \nClearance between Clearance between roller link  \nroller and bushing Clearance between bushing and pin  \nRoller plate and teeth  \nBusing  \nPin  \nSprocket  \nContact point between  \nChord pitch line  \nthe roller and teeth  \n(a) Clearance in teeth direction (b) Clearance in axis direction  \nEliminates time-consuming bore processing.  \nTSUBAKI offers 117 dimensions of standard bore processing and deliver them within a short time in response to orders. The standard tolerance of bore processing is based on H7 and support to the tolerances of press fitting too.  \nKeyway tolerances are in conformity with new JIS Js9 and P9 and old JIS F7 and E9 .  \nOrdering Information on Roller Chain Couplings  \n● Place each order with the product code and model number.  \n・ Body with Pilot bore  \n\n| Product code | Model no. | Quantity | Unit |\n| --- | --- | --- | --- |\n| P710001 | CR3812H | 10 | K (units) |\n\n● Model No.  \nPilot Bore (Body) CR 38 12 H  \nH: Body  \nNo. of sprocket teeth Chain no.  \nChain coupling  \n・ Casing (Sold separately.
