High-end type of the large power series
The DID HI-PWR-SHK roller chains have thicker link plates than HI-PWR-S roller chains, and are the highest in tensile strength and allowable load amongst general application chains, therefore staying appropriate for minimal pace hefty duty transmission.
Advisable uses
?The HI-PWR-SHK roller chains are 25 % increased in tensile strength and 50 percent higher in optimum allowable load compared to the standard roller chains, but since their weight is heavier, driving efficiency declines at higher velocity. So, they’re appropriate for hefty duty at reduced speed applications.

Multilevel parking machines, pipe benders, development machines, and so on.

Sprockets
Common sprockets for multiplex chains cannot be employed.
Connecting hyperlinks and offset backlinks
The ideal attribute on the HI-PWR-SHK roller chains is high optimum allowable load. Consequently, interference-fitted connecting back links (H connecting backlinks) with minor strength degradation are utilised.
The connecting plate plus the connecting pins are linked with spring pins. The tensile strength of an H connecting hyperlink is equivalent to that with the chain, however the allowable load is somewhat decrease than that from the chain.
HI-PWR-S kind roller chains don’t have any offset hyperlink. Use an even amount of hyperlinks.
Never ever make the holes of the connecting plate greater and under no circumstances make the pins thinner to facilitate the get the job done for fitting the pins into the connecting plate, considering the fact that otherwise the fatigue strength might be lowered.
