Substantial power roller chains with improved fatigue power and impact strength
HI-PWR-S roller chains are enhanced in fatigue strength and impact power devoid of altering the dimension while in the pin length course of regular roller chains. Plates are enlarged, plus the machining accuracy and assembling accuracy of components are enhanced. The roller chains hold high transmission efficiency for applications from reduced to high speeds and are impressive sufficient to withstand long-term use.
Advisable utilizes
?In contrast to common roller chains, HI-PWR-S roller chains are larger in greatest kilowatt rating by about 30 percent within a medium to minimal velocity variety. They exhibit fantastic capability in areas the place huge shock loads are applied, drive units for regular start/stop, and also in substantial pace applications.

?Civil engineering machines such as skid steer, trenchers, trucks, cranes, agitating trucks, forklifts and drive units for conveyors, elevators, stackers, etc.
Choice of chains
Generally, select your chain with reference to “Designing of Chain Transmission” and in addition to the tables of “Drive Performance” and “Dimensions” of HI-PWR-S form roller chains.Nevertheless, only for any unique case of reduced speed and significantly less shock, “Low-speed selection” is also applicable.
Sprockets
HI-PWR-S Roller chains and ANSI typical chains would be the identical in fundamental dimensions. Use ANSI common sprockets.
Connecting hyperlinks and offset hyperlinks
Use H connecting backlinks for HI-PWR-S. In an H connecting website link, the pins are lightly interference-fitted using the connecting plate. For your connection between the connecting plate as well as connecting pins, spring pins are employed in place of cotter pins for a normal roller chain.
The center plates of an H connecting website link for multiplex chain has bushings pressed in.
HI-PWR-S roller chains don’t have any offset link. Use an even number of backlinks.
In no way make the holes in the connecting plate larger and never ever make the pins thinner to facilitate the operate for fitting the pins to the connecting plate, given that otherwise the fatigue power are going to be lowered.
