High electrical power roller chains with enhanced fatigue strength and impact power
HI-PWR-S roller chains are enhanced in fatigue strength and influence power with out shifting the dimension inside the pin length path of conventional roller chains. Plates are enlarged, plus the machining accuracy and assembling accuracy of parts are enhanced. The roller chains hold substantial transmission efficiency for applications from very low to higher speeds and therefore are potent sufficient to withstand long-term use.
Advised makes use of
?In contrast to regular roller chains, HI-PWR-S roller chains are higher in optimum kilowatt rating by about thirty % in a medium to reduced velocity range. They exhibit outstanding capability in locations where substantial shock loads are utilized, drive units for regular start/stop, and in addition in high velocity applications.

?Civil engineering machines this kind of as skid steer, trenchers, trucks, cranes, agitating trucks, forklifts and drive units for conveyors, elevators, stackers, and so forth.
Choice of chains
Normally, pick your chain with reference to “Designing of Chain Transmission” and in addition to your tables of “Drive Performance” and “Dimensions” of HI-PWR-S type roller chains.Having said that, only for a specific case of low velocity and significantly less shock, “Low-speed selection” can also be applicable.
Sprockets
HI-PWR-S Roller chains and ANSI typical chains will be the same in simple dimensions. Use ANSI typical sprockets.
Connecting links and offset back links
Use H connecting backlinks for HI-PWR-S. In an H connecting link, the pins are lightly interference-fitted using the connecting plate. For your connection concerning the connecting plate along with the connecting pins, spring pins are made use of in place of cotter pins for any regular roller chain.
The center plates of an H connecting website link for multiplex chain has bushings pressed in.
HI-PWR-S roller chains never have any offset website link. Use an even number of links.
Never ever make the holes of the connecting plate greater and in no way make the pins thinner to facilitate the function for fitting the pins in to the connecting plate, due to the fact otherwise the fatigue strength is going to be lowered.
