Higher electrical power roller chains with improved fatigue strength and affect power
HI-PWR-S roller chains are enhanced in fatigue power and influence strength with out altering the dimension inside the pin length direction of conventional roller chains. Plates are enlarged, and the machining accuracy and assembling accuracy of elements are improved. The roller chains hold substantial transmission efficiency for applications from low to higher speeds and are powerful adequate to withstand long-term use.
Encouraged utilizes
?Compared to regular roller chains, HI-PWR-S roller chains are larger in optimum kilowatt rating by about 30 percent within a medium to reduced speed range. They exhibit great capability in locations the place large 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, and so on.
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 for any distinctive case of low pace and significantly less shock, “Low-speed selection” can be applicable.
Sprockets
HI-PWR-S Roller chains and ANSI standard chains are the same in primary dimensions. Use ANSI conventional sprockets.
Connecting hyperlinks and offset backlinks
Use H connecting links for HI-PWR-S. In an H connecting 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 to get 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.
