High-end variety of the large strength 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 standard application chains, so remaining appropriate for low velocity heavy duty transmission.
Suggested uses
?The HI-PWR-SHK roller chains are 25 percent larger in tensile strength and 50 % greater in optimum allowable load than the normal roller chains, but because their weight is heavier, driving overall performance declines at large speed. So, they’re suitable for hefty duty at reduced velocity applications.

Multilevel parking machines, pipe benders, development machines, etc.
Variety of chains
Select a good HI-PWR-SHK type chain depending on “Low-speed selection”
HI-PWR-SHK series is available in simplex.
Sprockets
Regular sprockets for multiplex chains cannot be employed.
Connecting hyperlinks and offset back links
The very best characteristic of your HI-PWR-SHK roller chains is substantial greatest allowable load. Therefore, interference-fitted connecting hyperlinks (H connecting back links) with minor power degradation are used.
The connecting plate and the connecting pins are linked with spring pins. The tensile power of an H connecting link is equivalent to that on the chain, but the allowable load is relatively reduced than that from the chain.
HI-PWR-S variety roller chains don’t have any offset hyperlink. Use an even variety of hyperlinks.
Never make the holes from the connecting plate more substantial and never make the pins thinner to facilitate the work for fitting the pins in to the connecting plate, given that otherwise the fatigue power will likely be lowered.
