High power roller chains with improved fatigue power and effect strength
HI-PWR-S roller chains are enhanced in fatigue strength and affect strength with no modifying the dimension within the pin length course of standard roller chains. Plates are enlarged, and the machining accuracy and assembling accuracy of parts are improved. The roller chains hold substantial transmission efficiency for applications from lower to substantial speeds and are strong adequate to stand up to long-term use.
Proposed uses
?In contrast to normal roller chains, HI-PWR-S roller chains are larger in highest kilowatt rating by about 30 % in the medium to reduced velocity array. They exhibit superb capability in areas wherever large shock loads are utilized, drive units for regular start/stop, and also in large pace applications.

?Civil engineering machines such as skid steer, trenchers, trucks, cranes, agitating trucks, forklifts and drive units for conveyors, elevators, stackers, and so forth.
Selection of chains
On the whole, decide on your chain with reference to “Designing of Chain Transmission” and also to your tables of “Drive Performance” and “Dimensions” of HI-PWR-S type roller chains.Having said that, only for a unique situation of low pace and much less shock, “Low-speed selection” can also be applicable.
HI-PWR-S Roller chains and ANSI common chains will be the same in standard dimensions. Use ANSI regular sprockets.
Connecting backlinks and offset back links
Use H connecting back links for HI-PWR-S. In an H connecting hyperlink, the pins are lightly interference-fitted using the connecting plate. For the connection among the connecting plate along with the connecting pins, spring pins are applied as an alternative to cotter pins for a regular roller chain.
The center plates of an H connecting link for multiplex chain has bushings pressed in.
HI-PWR-S roller chains don’t have any offset hyperlink. Use an even amount of back links.
Never make the holes with the connecting plate more substantial and hardly ever make the pins thinner to facilitate the function for fitting the pins into the connecting plate, given that otherwise the fatigue strength might be lowered.
