High power roller chains with improved fatigue strength and affect power
HI-PWR-S roller chains are enhanced in fatigue strength and influence strength without modifying the dimension while in the pin length path of standard roller chains. Plates are enlarged, as well as machining accuracy and assembling accuracy of parts are enhanced. The roller chains hold high transmission efficiency for applications from lower to substantial speeds and are effective ample to stand up to long-term use.
Recommended employs
?Compared to conventional roller chains, HI-PWR-S roller chains are greater in greatest kilowatt rating by about 30 percent in a medium to very low speed range. They exhibit fantastic capability in places 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 towards the tables of “Drive Performance” and “Dimensions” of HI-PWR-S type roller chains.Having said that, only for any unique case of lower speed and much less shock, “Low-speed selection” is additionally applicable.
HI-PWR-S Roller chains and ANSI common chains will be the same in basic dimensions. Use ANSI common sprockets.
Connecting backlinks and offset backlinks
Use H connecting links for HI-PWR-S. In an H connecting website link, the pins are lightly interference-fitted using 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.
Hardly ever make the holes of the connecting plate greater and by no means make the pins thinner to facilitate the do the job for fitting the pins into the connecting plate, because otherwise the fatigue strength will be lowered.
