Higher energy roller chains with improved fatigue strength and affect power
HI-PWR-S roller chains are enhanced in fatigue strength and impact strength with out altering the dimension within the pin length direction of conventional roller chains. Plates are enlarged, and the machining accuracy and assembling accuracy of elements are enhanced. The roller chains hold substantial transmission efficiency for applications from low to high speeds and are powerful adequate to stand up to long-term use.
Encouraged utilizes
?Compared to standard roller chains, HI-PWR-S roller chains are larger in maximum kilowatt rating by about 30 percent within a medium to low speed range. They exhibit great capability in locations the place substantial shock loads are applied, drive units for regular start/stop, and also in substantial speed applications.

?Civil engineering machines this kind of as skid steer, trenchers, trucks, cranes, agitating trucks, forklifts and drive units for conveyors, elevators, stackers, etc.
Choice of chains
In general, pick your chain with reference to “Designing of Chain Transmission” as well as to your tables of “Drive Performance” and “Dimensions” of HI-PWR-S kind roller chains.On the other hand, only to get a specific situation of low pace and significantly less shock, “Low-speed selection” is additionally applicable.
HI-PWR-S Roller chains and ANSI typical chains are the same in standard dimensions. Use ANSI typical sprockets.
Connecting hyperlinks and offset backlinks
Use H connecting back links for HI-PWR-S. In an H connecting website link, the pins are lightly interference-fitted together with the connecting plate. For your connection amongst the connecting plate along with the connecting pins, spring pins are utilised as an alternative to cotter pins for a regular roller chain.
The center plates of an H connecting hyperlink for multiplex chain has bushings pressed in.
HI-PWR-S roller chains never have any offset link. Use an even number of hyperlinks.
Never ever make the holes on the connecting plate bigger and hardly ever make the pins thinner to facilitate the function for fitting the pins into the connecting plate, due to the fact otherwise the fatigue strength will likely be lowered.
