High power roller chains with enhanced fatigue strength and influence strength
HI-PWR-S roller chains are enhanced in fatigue strength and affect strength without changing the dimension in the pin length route 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
?In contrast to conventional roller chains, HI-PWR-S roller chains are greater in greatest kilowatt rating by about 30 percent in a medium to very low speed selection. They exhibit exceptional capability in places exactly where massive shock loads are applied, drive units for frequent start/stop, and also in large velocity applications.

?Civil engineering machines such as skid steer, trenchers, trucks, cranes, agitating trucks, forklifts and drive units for conveyors, elevators, stackers, and so forth.
Selection of chains
Usually, choose your chain with reference to “Designing of Chain Transmission” and also for the tables of “Drive Performance” and “Dimensions” of HI-PWR-S type roller chains.Nonetheless, only to get a particular situation of very low speed and much less shock, “Low-speed selection” can also be applicable.
Sprockets
HI-PWR-S Roller chains and ANSI common chains are the similar in simple dimensions. Use ANSI common sprockets.
Connecting links and offset hyperlinks
Use H connecting backlinks for HI-PWR-S. In an H connecting website link, the pins are lightly interference-fitted with all the connecting plate. For the connection between the connecting plate and the connecting pins, spring pins are used rather than cotter pins for any standard roller chain.
The center plates of an H connecting link for multiplex chain has bushings pressed in.
HI-PWR-S roller chains usually do not have any offset link. Use an even amount of hyperlinks.
Never make the holes of the connecting plate larger and in no way make the pins thinner to facilitate the work for fitting the pins in to the connecting plate, considering that otherwise the fatigue strength will be lowered.
