The chain is located at the external surface of the wheel, equal a belt, and one’s teeth stick beyond your chain. The chain grips with the wheel through the teeth that are located at the bottom of the chain. The chain the teeth and the chain wheel tooth are therefore constituted that by use at the linking elements the pitch improves, the chain accordingly tend to re-locate on the tooth surfaces, so to grip on a larger pitch diameter; the consequence of this move is usually that the pitch of the chain and the pitch of the wheel increase to the same level.
The load on the teeth is divided across all the teeth within the contact arc, regardless of the extension by wear.
The links do not display any gliding on or of one’s teeth, which carries a soft and practically noiseless gripping; this tranny was also manufactured for transmitting power or more speeds than this is 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 smartly designed transmission under average operating conditions.
The Special Chains china lifetime and maintenance of low noise chains depends mainly on the look of the entire 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. Hook clearance is necessary with at the least +/-3 mm. Although the chain gets higher positioned on the teeth upon stretching of the pitch, this stretching isn’t moderated by the directly portion of the chain, which implies that this section is certainly slacking at wear.
