High electrical power roller chains with improved fatigue strength and affect power
HI-PWR-S roller chains are enhanced in fatigue power and influence strength without having shifting the dimension during the pin length route of conventional roller chains. Plates are enlarged, along with the machining accuracy and assembling accuracy of parts are improved. The roller chains hold high transmission efficiency for applications from very low to substantial speeds and are powerful adequate to stand up to long-term use.
Advised makes use of
?In contrast to typical roller chains, HI-PWR-S roller chains are increased in maximum kilowatt rating by about 30 % within a medium to very low velocity variety. They exhibit exceptional capability in places in which substantial shock loads are utilized, drive units for frequent start/stop, and also in high speed applications.

?Civil engineering machines such as skid steer, trenchers, trucks, cranes, agitating trucks, forklifts and drive units for conveyors, elevators, stackers, etc.
Selection of chains
Usually, select your chain with reference to “Designing of Chain Transmission” as well as to your tables of “Drive Performance” and “Dimensions” of HI-PWR-S style roller chains.However, only for a unique case of lower velocity and significantly less shock, “Low-speed selection” can also be applicable.
HI-PWR-S Roller chains and ANSI standard chains are the identical in basic dimensions. Use ANSI regular 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 with the connecting plate. For that connection in between the connecting plate plus the connecting pins, spring pins are applied rather than cotter pins for any regular roller chain.
The center plates of an H connecting website link for multiplex chain has bushings pressed in.
HI-PWR-S roller chains do not have any offset hyperlink. Use an even number of hyperlinks.
Never make the holes on the connecting plate bigger and hardly ever make the pins thinner to facilitate the function for fitting the pins to the connecting plate, considering that otherwise the fatigue power might be lowered.
