Large power roller chains with enhanced fatigue power and impact strength
HI-PWR-S roller chains are enhanced in fatigue power and affect power without having transforming the dimension inside the pin length route of conventional roller chains. Plates are enlarged, as well as the machining accuracy and assembling accuracy of parts are enhanced. The roller chains hold large transmission efficiency for applications from low to substantial speeds and therefore are highly effective enough to withstand long-term use.
Advised employs
?Compared to normal roller chains, HI-PWR-S roller chains are greater in highest kilowatt rating by about thirty % inside a medium to minimal pace selection. They exhibit great capability in locations in which significant shock loads are applied, drive units for regular start/stop, as well as in higher velocity 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
Generally, decide on your chain with reference to “Designing of Chain Transmission” and in addition to your tables of “Drive Performance” and “Dimensions” of HI-PWR-S variety roller chains.On the other hand, only for any special case of low speed and much less shock, “Low-speed selection” can be applicable.
Sprockets
HI-PWR-S Roller chains and ANSI common chains would be the same in basic dimensions. Use ANSI normal sprockets.
Connecting back links and offset links
Use H connecting hyperlinks for HI-PWR-S. In an H connecting hyperlink, the pins are lightly interference-fitted together with the connecting plate. For the connection concerning the connecting plate plus the connecting pins, spring pins are utilized as an alternative to cotter pins to get a 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 website link. Use an even amount of hyperlinks.
Hardly ever make the holes from the connecting plate larger and in no way make the pins thinner to facilitate the perform for fitting the pins to the connecting plate, because otherwise the fatigue power is going to be lowered.
