The chain is located at the external surface area of the wheel, equal a belt, and the teeth stick beyond your chain. The chain grips with the wheel through tooth that are located in the bottom of the chain. The chain teeth and the chain wheel tooth are so constituted that by wear at the linking elements the pitch raises, the chain accordingly tend to re-locate on the tooth surfaces, so to hold on a more substantial pitch diameter; the consequence of this move is certainly that the pitch of the chain and the pitch of the wheel increase to the same extent.
The load on one’s teeth is divided across all of the teeth within the contact arc, whatever the extension by wear.
The links do not display any gliding on or of one’s teeth, which posesses soft and practically noiseless gripping; this tranny was also designed for transmitting power or more speeds than this was allowed for roll chains.
The return of the “low noise chain” can amount 99% and for the entire transfer from 96% to 97% under favourable conditions; of 94% upto 96% there exists a guarantee with well designed transmission under average operating conditions.
The lifetime and maintenance of low noise chains depends mainly on the look of the complete chain drive, the tension arrangement included. At very loose chains the balancing of the chain will increase the wear. A good tension arrangement can double the lifetime. A slight clearance is required with a minimum of +/-3 mm. Although the chain is getting higher positioned on one’s teeth upon stretching of the pitch, this stretching is not moderated by the directly portion of the chain, which Special Chains china implies that this section 
is usually slacking at wear.
