High power roller chains with improved fatigue strength and impact strength
HI-PWR-S roller chains are enhanced in fatigue power and impact strength without the need of transforming the dimension inside the pin length route of conventional roller chains. Plates are enlarged, as well as the machining accuracy and assembling accuracy of parts are improved. The roller chains hold substantial transmission efficiency for applications from low to higher speeds and are powerful enough to withstand long-term use.
Suggested employs
?Compared to common roller chains, HI-PWR-S roller chains are increased in highest kilowatt rating by about thirty percent inside a medium to lower velocity array. They exhibit outstanding capability in destinations in which significant shock loads are applied, 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 on.
Choice of chains
Normally, pick your chain with reference to “Designing of Chain Transmission” and also to the tables of “Drive Performance” and “Dimensions” of HI-PWR-S kind roller chains.On the other hand, only for a special case of minimal pace and less shock, “Low-speed selection” can be applicable.
Sprockets
HI-PWR-S Roller chains and ANSI normal chains will be the very same in standard dimensions. Use ANSI normal sprockets.
Connecting backlinks and offset backlinks
Use H connecting hyperlinks for HI-PWR-S. In an H connecting hyperlink, the pins are lightly interference-fitted together with the connecting plate. To the connection among the connecting plate and also the connecting pins, spring pins are made use of as an alternative to cotter pins for any regular 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 hyperlink. Use an even number of links.
Under no circumstances make the holes on the connecting plate bigger and in no way make the pins thinner to facilitate the get the job done for fitting the pins in to the connecting plate, since otherwise the fatigue power are going to be lowered.
