The chain is situated at the external surface of the wheel, equal a belt, and one’s teeth stick outside the chain. The chain grips with the wheel through teeth that are located in the bottom of the chain. The chain tooth and the chain wheel teeth are so constituted that by use at the linking components the pitch raises, the chain accordingly have a tendency to re-locate on the tooth surfaces, so to grasp on a larger pitch diameter; the consequence of this move is that the pitch of the chain and the pitch of the wheel boost to the same extent.
The load on the teeth 
is divided across all the teeth within the contact arc, whatever 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 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 full transfer from 96% to 97% under favourable conditions; of 94% upto 96% there exists a guarantee with smartly designed transmission under typical operating conditions.
The lifetime and maintenance of low noise chains depends mainly on the design of the entire chain drive, the strain arrangement included. At very loose chains the balancing of the chain will increase the wear. An excellent tension arrangement can double the lifetime. Hook clearance is required with a minimum of +/-3 mm. Although the chain is getting higher positioned on the teeth upon Special Chains china stretching of the pitch, this stretching is not moderated by the straight section of the chain, which means that this section can be slacking at wear.
