High power roller chains with improved fatigue strength and effect power
HI-PWR-S roller chains are enhanced in fatigue power and effect power devoid of changing the dimension in the pin length direction of standard roller chains. Plates are enlarged, along with the machining accuracy and assembling accuracy of parts are enhanced. The roller chains hold higher transmission efficiency for applications from low to high speeds and are powerful enough to withstand long-term use.
Suggested employs
?Compared to typical roller chains, HI-PWR-S roller chains are larger in optimum kilowatt rating by about 30 % in a medium to minimal speed selection. They exhibit fantastic capability in areas wherever big shock loads are applied, drive units for frequent start/stop, and also in large speed applications.

?Civil engineering machines such as skid steer, trenchers, trucks, cranes, agitating trucks, forklifts and drive units for conveyors, elevators, stackers, and so on.
Choice of chains
On the whole, select your chain with reference to “Designing of Chain Transmission” and also for the tables of “Drive Performance” and “Dimensions” of HI-PWR-S variety roller chains.On the other hand, only for a special situation of lower speed and much less shock, “Low-speed selection” can be applicable.
HI-PWR-S Roller chains and ANSI conventional chains will be the exact same in fundamental dimensions. Use ANSI regular sprockets.
Connecting links and offset hyperlinks
Use H connecting links for HI-PWR-S. In an H connecting link, the pins are lightly interference-fitted using the connecting plate. To the connection between the connecting plate and the connecting pins, spring pins are employed rather than cotter pins for a standard roller chain.
The center plates of an H connecting hyperlink for multiplex chain has bushings pressed in.
HI-PWR-S roller chains do not have any offset website link. Use an even variety of hyperlinks.
Never make the holes on the connecting plate bigger and never make the pins thinner to facilitate the perform for fitting the pins in to the connecting plate, because otherwise the fatigue strength will be lowered.
