Higher power roller chains with enhanced fatigue strength and impact strength
HI-PWR-S roller chains are enhanced in fatigue strength and influence strength without transforming the dimension while in the pin length direction of common 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 very low to substantial speeds and are powerful enough to stand up to long-term use.
Advised utilizes
?In contrast to standard roller chains, HI-PWR-S roller chains are larger in highest kilowatt rating by about thirty % in the medium to reduced pace selection. They exhibit fantastic capability in places wherever huge shock loads are utilized, drive units for frequent start/stop, as well as in substantial 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
Generally, choose your chain with reference to “Designing of Chain Transmission” as well as to the tables of “Drive Performance” and “Dimensions” of HI-PWR-S type roller chains.Nevertheless, only for any special situation of reduced pace and much less shock, “Low-speed selection” can also be applicable.
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 links for HI-PWR-S. In an H connecting link, the pins are lightly interference-fitted with all the connecting plate. For that connection in between the connecting plate as well as the connecting pins, spring pins are utilized in lieu of cotter pins to get a conventional 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 link. Use an even quantity of links.
By no means make the holes with the connecting plate larger and in no way make the pins thinner to facilitate the function for fitting the pins in to the connecting plate, considering that otherwise the fatigue strength will likely be lowered.
