High energy roller chains with improved fatigue strength and affect power
HI-PWR-S roller chains are enhanced 
in fatigue strength and influence power without having modifying the dimension while in the pin length path of standard roller chains. Plates are enlarged, and also the machining accuracy and assembling accuracy of components are improved. The roller chains hold higher transmission efficiency for applications from lower to substantial speeds and are strong ample to stand up to long-term use.
Recommended uses
?Compared to standard roller chains, HI-PWR-S roller chains are larger in greatest kilowatt rating by about thirty percent in a medium to low pace range. They exhibit excellent capability in areas exactly where large shock loads are applied, drive units for regular start/stop, and in addition in higher pace applications.
?Civil engineering machines this kind of as skid steer, trenchers, trucks, cranes, agitating trucks, forklifts and drive units for conveyors, elevators, stackers, etc.
Collection of chains
Generally, pick your chain with reference to “Designing of Chain Transmission” and also for the tables of “Drive Performance” and “Dimensions” of HI-PWR-S type roller chains.Nevertheless, only for a particular case of minimal speed and much less shock, “Low-speed selection” is additionally applicable.
Sprockets
HI-PWR-S Roller chains and ANSI common chains will be the same in simple dimensions. Use ANSI common sprockets.
Connecting backlinks and offset backlinks
Use H connecting links for HI-PWR-S. In an H connecting link, the pins are lightly interference-fitted with all the connecting plate. To the connection in between the connecting plate as well as the connecting pins, spring pins are applied in lieu of 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 don’t have any offset link. Use an even quantity of links.
By no means make the holes from the connecting plate greater and never make the pins thinner to facilitate the work for fitting the pins in to the connecting plate, because otherwise the fatigue strength will be lowered.
