High-end kind of the high strength series
The DID HI-PWR-SHK roller chains have thicker website link plates than HI-PWR-S roller chains, and are the highest in tensile strength and allowable load amongst common application chains, hence becoming ideal for reduced velocity hefty duty transmission.
Advisable utilizes
?The HI-PWR-SHK roller chains are 25 % larger in tensile strength and 50 % increased in optimum allowable load than the regular roller chains, but considering the fact that their excess weight is heavier, driving effectiveness declines at high pace. So, they are appropriate for heavy duty at reduced velocity applications.

Multilevel parking machines, pipe benders, building machines, and so on.
Choice of chains
Pick a suitable HI-PWR-SHK type chain depending on “Low-speed selection”
HI-PWR-SHK series is obtainable in simplex.
Sprockets
Standard sprockets for multiplex chains are unable to be utilized.
Connecting hyperlinks and offset backlinks
The most beneficial feature from the HI-PWR-SHK roller chains is higher optimum allowable load. Hence, interference-fitted connecting links (H connecting backlinks) with very little strength degradation are used.
The connecting plate as well as connecting pins are linked with spring pins. The tensile power of an H connecting website link is equivalent to that with the chain, however the allowable load is relatively reduce than that on the chain.
HI-PWR-S type roller chains do not have any offset hyperlink. Use an even variety of backlinks.
Under no circumstances make the holes on the connecting plate larger and in no way make the pins thinner to facilitate the function for fitting the pins to the connecting plate, considering that otherwise the fatigue power will be lowered.
