High-end style of the higher strength 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 strength and allowable load among common application chains, hence being suitable for lower velocity heavy duty transmission.
Advised makes use of
?The HI-PWR-SHK roller chains are 25 percent larger in tensile strength and 50 % higher in highest allowable load than the regular roller chains, but since their excess weight is heavier, driving performance declines at large speed. So, they may be appropriate for hefty duty at lower speed applications.

Collection of chains
Pick a correct HI-PWR-SHK type chain determined by “Low-speed selection”
HI-PWR-SHK series is obtainable in simplex.
Sprockets
Regular sprockets for multiplex chains can not be applied.
Connecting back links and offset back links
The most effective function from the HI-PWR-SHK roller chains is high optimum allowable load. Therefore, interference-fitted connecting links (H connecting hyperlinks) with minor strength degradation are used.
The connecting plate as well as the connecting pins are connected with spring pins. The tensile strength of an H connecting link is equivalent to that on the chain, but the allowable load is relatively reduced than that in the chain.
HI-PWR-S kind roller chains don’t have any offset hyperlink. Use an even number of hyperlinks.
Under no circumstances make the holes in the connecting plate bigger and never make the pins thinner to facilitate the work for fitting the pins in to the connecting plate, due to the fact otherwise the fatigue strength is going to be lowered.
