High-end kind of the substantial power series
The DID HI-PWR-SHK roller chains have thicker link plates than HI-PWR-S roller chains, and therefore are the highest in tensile power and allowable load between general application chains, therefore becoming suitable for lower velocity hefty duty transmission.
Advised uses
?The HI-PWR-SHK roller chains are 25 percent larger in tensile strength and 50 percent greater in optimum allowable load than the regular roller chains, but due to the fact their fat is heavier, driving overall performance declines at higher velocity. So, they’re appropriate for heavy duty at lower speed applications.

Multilevel parking machines, pipe benders, building machines, etc.
Choice of chains

HI-PWR-SHK series is available in simplex.
Common sprockets for multiplex chains are not able to be utilised.
Connecting back links and offset links
The most effective characteristic on the HI-PWR-SHK roller chains is large maximum allowable load. Therefore, interference-fitted connecting backlinks (H connecting backlinks) with small strength degradation are applied.
The connecting plate as well as connecting pins are linked with spring pins. The tensile strength of an H connecting link is equivalent to that from the chain, but the allowable load is somewhat lower than that from the chain.
HI-PWR-S sort roller chains don’t have any offset link. Use an even number of hyperlinks.
By no means make the holes in the connecting plate larger and never ever make the pins thinner to facilitate the function for fitting the pins to the connecting plate, due to the fact otherwise the fatigue strength will probably be lowered.
