Higher electrical power roller chains with improved fatigue strength and affect strength
HI-PWR-S roller chains are enhanced in fatigue strength and effect power with out transforming the dimension from the pin length direction of common roller chains. Plates are enlarged, along with the machining accuracy and assembling accuracy of components are enhanced. The roller chains hold high transmission efficiency for applications from very low to substantial speeds and are impressive enough to withstand long-term use.
Advised utilizes
?In contrast to regular roller chains, HI-PWR-S roller chains are larger in highest kilowatt rating by about 30 % in the medium to reduced velocity assortment. They exhibit exceptional capability in places wherever massive shock loads are utilized, drive units for frequent start/stop, as well as in large velocity applications.

?Civil engineering machines this kind of as skid steer, trenchers, trucks, cranes, agitating trucks, forklifts and drive units for conveyors, elevators, stackers, etc.
Choice of chains
Normally, choose your chain with reference to “Designing of Chain Transmission” as well as to your tables of “Drive Performance” and “Dimensions” of HI-PWR-S type roller chains.Nevertheless, only for any special case of reduced pace and much less shock, “Low-speed selection” can also be applicable.
Sprockets
HI-PWR-S Roller chains and ANSI typical chains are the similar in standard dimensions. Use ANSI regular sprockets.
Connecting hyperlinks and offset backlinks
Use H connecting hyperlinks for HI-PWR-S. In an H connecting hyperlink, the pins are lightly interference-fitted with all the connecting plate. To the connection in between the connecting plate along with the connecting pins, spring pins are used instead of cotter pins to get a typical roller chain.
The center plates of an H connecting website link for multiplex chain has bushings pressed in.
HI-PWR-S roller chains usually do not have any offset website link. Use an even quantity of back links.
By no means make the holes with the connecting plate bigger and in no way make the pins thinner to facilitate the perform for fitting the pins to the connecting plate, given that otherwise the fatigue power is going to be lowered.
