High electrical power roller chains with enhanced fatigue strength and effect power
HI-PWR-S roller chains are enhanced in fatigue strength and affect strength without having altering the dimension within the pin length path of standard roller chains. Plates are enlarged, and also the machining accuracy and assembling accuracy of elements are enhanced. The roller chains hold high transmission efficiency for applications from reduced to large speeds and are effective enough to stand up to long-term use.
Suggested employs
?In contrast to normal roller chains, HI-PWR-S roller chains are greater in highest kilowatt rating by about 30 percent within a medium to lower pace assortment. They exhibit superb capability in places the place significant shock loads are applied, drive units for regular start/stop, and also in large speed applications.

?Civil engineering machines such as skid steer, trenchers, trucks, cranes, agitating trucks, forklifts and drive units for conveyors, elevators, stackers, and so on.
Choice of chains
Generally, choose your chain with reference to “Designing of Chain Transmission” as well as for the tables of “Drive Performance” and “Dimensions” of HI-PWR-S style roller chains.On the other hand, only for any special situation of low pace and much less shock, “Low-speed selection” can be applicable.
Sprockets
HI-PWR-S Roller chains and ANSI conventional chains are the identical in fundamental dimensions. Use ANSI typical sprockets.
Connecting links and offset backlinks
Use H connecting back links for HI-PWR-S. In an H connecting link, the pins are lightly interference-fitted using the connecting plate. For the connection involving the connecting plate plus the connecting pins, spring pins are applied as an alternative to cotter pins for any normal roller chain.
The center plates of an H connecting link for multiplex chain has bushings pressed in.
HI-PWR-S roller chains usually do not have any offset link. Use an even variety of hyperlinks.
Never ever make the holes on the connecting plate greater and never ever make the pins thinner to facilitate the work for fitting the pins in to the connecting plate, because otherwise the fatigue power might be lowered.
