High-end variety of the high strength series
The DID HI-PWR-SHK roller chains have thicker hyperlink plates than HI-PWR-S roller chains, and are the highest in tensile strength and allowable load between standard application chains, so being ideal for very low velocity heavy duty transmission.
Encouraged employs
?The HI-PWR-SHK roller chains are 25 percent increased in tensile power and 50 % greater in greatest allowable load than the normal roller chains, but since their fat is heavier, driving overall performance declines at high velocity. So, they are appropriate for heavy duty at low velocity applications.

Multilevel parking machines, pipe benders, development machines, etc.
Choice of chains
Pick a correct HI-PWR-SHK variety chain according to “Low-speed selection”
HI-PWR-SHK series is obtainable in simplex.
Standard sprockets for multiplex chains can’t be used.
Connecting back links and offset back links
The very best feature on the HI-PWR-SHK roller chains is higher optimum allowable load. For that reason, interference-fitted connecting backlinks (H connecting backlinks) with little strength degradation are utilised.
The connecting plate along with the connecting pins are linked with spring pins. The tensile strength of an H connecting website link is equivalent to that in the chain, however the allowable load is somewhat reduce than that with the chain.
HI-PWR-S style roller chains don’t have any offset hyperlink. Use an even quantity of hyperlinks.
By no means make the holes from the connecting plate larger and hardly ever make the pins thinner to facilitate the work for fitting the pins in to the connecting plate, since otherwise the fatigue power will probably be lowered.
