High energy roller chains with improved fatigue strength and effect power
HI-PWR-S roller chains are enhanced in fatigue power and impact strength without changing the dimension in the pin length course of typical roller chains. Plates are enlarged, as well as machining accuracy and assembling accuracy of elements are enhanced. The roller chains hold large transmission efficiency for applications from very low to high speeds and are impressive sufficient to stand up to long-term use.
Advisable utilizes
?Compared to conventional roller chains, HI-PWR-S roller chains are greater in maximum kilowatt rating by about 30 percent inside a medium to low speed array. They exhibit exceptional capability in places in which substantial shock loads are applied, drive units for regular start/stop, and also in substantial velocity applications.

?Civil engineering machines such as skid steer, trenchers, trucks, cranes, agitating trucks, forklifts and drive units for conveyors, elevators, stackers, etc.
Selection of chains
Usually, choose your chain with reference to “Designing of Chain Transmission” and also on the tables of “Drive Performance” and “Dimensions” of HI-PWR-S type roller chains.Even so, only for any specific situation of very low speed and much less shock, “Low-speed selection” is additionally applicable.
HI-PWR-S Roller chains and ANSI conventional chains are the similar in standard dimensions. Use ANSI typical sprockets.
Connecting links and offset backlinks
Use H connecting back links for HI-PWR-S. In an H connecting website link, the pins are lightly interference-fitted with all the connecting plate. For the connection among the connecting plate as well as the connecting pins, spring pins are employed as opposed to cotter pins for a standard roller chain.
The center plates of an H connecting link for multiplex chain has bushings pressed in.
HI-PWR-S roller chains will not have any offset link. Use an even number of hyperlinks.
In no way make the holes in the connecting plate bigger and under no circumstances make the pins thinner to facilitate the work for fitting the pins to the connecting plate, considering that otherwise the fatigue strength will probably be lowered.
