Higher power roller chains with improved fatigue strength and influence strength
HI-PWR-S roller chains are enhanced in fatigue strength and affect power without modifying the dimension from the pin length direction of typical roller chains. Plates are enlarged, and the machining accuracy and assembling accuracy of parts are enhanced. The roller chains hold higher transmission efficiency for applications from low to high speeds and therefore are effective sufficient to stand up to long-term use.
Recommended makes use of
?In contrast to common roller chains, HI-PWR-S roller chains are increased in greatest kilowatt rating by about 30 % within a medium to very low speed array. They exhibit outstanding capability in spots where massive shock loads are utilized, drive units for regular start/stop, as well as in high pace 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
In general, select your chain with reference to “Designing of Chain Transmission” and also on the tables of “Drive Performance” and “Dimensions” of HI-PWR-S type roller chains.Having said that, only for a particular case of reduced velocity and less shock, “Low-speed selection” can be applicable.
Sprockets
HI-PWR-S Roller chains and ANSI common chains are the exact same in primary dimensions. Use ANSI regular sprockets.
Connecting hyperlinks 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 concerning the connecting plate as well as the connecting pins, spring pins are made use of in lieu of cotter pins to get a standard roller chain.
The center plates of an H connecting hyperlink for multiplex chain has bushings pressed in.
HI-PWR-S roller chains do not have any offset link. Use an even variety of links.
In no way make the holes from the connecting plate greater and never ever make the pins thinner to facilitate the work for fitting the pins in to the connecting plate, considering the fact that otherwise the fatigue power might be lowered.
