High-end form 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, hence staying suitable for very low velocity hefty duty transmission.
Proposed employs
?The HI-PWR-SHK roller chains are 25 percent higher in tensile strength and 50 percent greater in highest allowable load compared to the conventional roller chains, but because their excess weight is heavier, driving efficiency declines at substantial pace. So, they are appropriate for heavy duty at low pace applications.

Multilevel parking machines, pipe benders, development machines, and so on.
Selection of chains
Select a proper HI-PWR-SHK type chain based on “Low-speed selection”
HI-PWR-SHK series is obtainable in simplex.
Typical sprockets for multiplex chains are unable to be employed.
Connecting back links and offset backlinks
The most beneficial feature of the HI-PWR-SHK roller chains is substantial optimum allowable load. Hence, interference-fitted connecting backlinks (H connecting links) with little power degradation are employed.
The connecting plate and the connecting pins are linked with spring pins. The tensile strength of an H connecting hyperlink is equivalent to that of the chain, but the allowable load is relatively reduced than that of the chain.
HI-PWR-S variety roller chains don’t have any offset link. Use an even variety of links.
Under no circumstances make the holes of your connecting plate bigger and never make the pins thinner to facilitate the work for fitting the pins to the connecting plate, because otherwise the fatigue strength might be lowered.
