Large power roller chains with enhanced fatigue strength and effect power
HI-PWR-S roller chains are enhanced in fatigue strength and influence strength devoid of shifting the dimension from the pin length route of typical roller chains. Plates are enlarged, as well as the machining accuracy and assembling accuracy of elements are improved. The roller chains hold high transmission efficiency for applications from minimal to higher speeds and therefore are highly effective adequate to stand up to long-term use.
Recommended makes use of
?Compared to conventional roller chains, HI-PWR-S roller chains are increased in highest kilowatt rating by about thirty % within a medium to very low speed selection. They exhibit great capability in areas exactly where substantial shock loads are applied, drive units for frequent start/stop, and in addition in higher velocity applications.

?Civil engineering machines such as skid steer, trenchers, trucks, cranes, agitating trucks, forklifts and drive units for conveyors, elevators, stackers, and so on.
Variety of chains
On the whole, pick your chain with reference to “Designing of Chain Transmission” as well as to your tables of “Drive Performance” and “Dimensions” of HI-PWR-S style roller chains.Nevertheless, only for any unique case of reduced pace and much less shock, “Low-speed selection” can be applicable.
HI-PWR-S Roller chains and ANSI regular chains are the identical in standard dimensions. Use ANSI common sprockets.
Connecting links and offset hyperlinks
Use H connecting back links for HI-PWR-S. In an H connecting link, the pins are lightly interference-fitted with all the connecting plate. For your connection in between the connecting plate plus the connecting pins, spring pins are used instead of cotter pins for any standard roller chain.
The center plates of an H connecting website link for multiplex chain has bushings pressed in.
HI-PWR-S roller chains tend not to have any offset website link. Use an even quantity of backlinks.
Never ever make the holes of your connecting plate more substantial and never make the pins thinner to facilitate the do the job for fitting the pins in to the connecting plate, considering that otherwise the fatigue power will probably be lowered.
