The chain is situated at the external surface of 
the wheel, equal a belt, and the teeth stick outside the chain. The chain grips with the wheel through tooth that are located in 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 increases, the chain accordingly tend to move out on the tooth surfaces, so to grasp on a more substantial pitch diameter; the result of this move is certainly that the pitch of the chain and the pitch of the wheel increase to the same degree.
The load on one's 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 the teeth, which posesses soft and practically noiseless gripping; this transmitting was also engineered for transmitting power or higher speeds than this is allowed for roll chains.
The return of the “low noise chain” can amount 99% and for the full transfer from 96% to 97% under favourable conditions; of 94% upto 96% there exists a guarantee with well designed transmission under typical operating conditions.
The life time and maintenance of low noise chains depends mainly on the design of the entire chain drive, the tension arrangement Special Chains included. At very loose chains the balancing of the chain will speed up the wear. A good tension arrangement can dual the lifetime. A slight clearance is required with at the least +/-3 mm. Although the chain is getting higher positioned on one's teeth upon stretching of the pitch, this stretching isn't moderated by the straight section of the chain, which means that this section can be slacking at wear.
