High power roller chains with enhanced fatigue strength and influence power
HI-PWR-S roller chains are enhanced in fatigue strength and impact strength with out altering the dimension in the pin length route of standard roller chains. Plates are enlarged, plus the machining accuracy and assembling accuracy of parts are improved. The roller chains hold high transmission efficiency for applications from minimal to higher speeds and are effective adequate to withstand long-term use.
Suggested uses
?Compared to common roller chains, HI-PWR-S roller chains are larger in greatest kilowatt rating by about 30 % inside a medium to very low speed assortment. They exhibit superb capability in locations where huge shock loads are applied, drive units for regular start/stop, as well as in large velocity applications.

?Civil engineering machines this kind of as skid steer, trenchers, trucks, cranes, agitating trucks, forklifts and drive units for conveyors, elevators, stackers, etc.
Choice of chains
Generally, decide on your chain with reference to “Designing of Chain Transmission” and in addition to your tables of “Drive Performance” and “Dimensions” of HI-PWR-S sort roller chains.However, only to get a distinctive situation of lower speed and less shock, “Low-speed selection” is also applicable.
Sprockets
HI-PWR-S Roller chains and ANSI common chains would be the identical in simple dimensions. Use ANSI common sprockets.
Connecting hyperlinks and offset links
Use H connecting hyperlinks for HI-PWR-S. In an H connecting website link, the pins are lightly interference-fitted using the connecting plate. For the connection among the connecting plate along with the connecting pins, spring pins are utilised as opposed to cotter pins for any normal 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 hyperlink. Use an even quantity of back links.
Never ever make the holes in the connecting plate greater and hardly ever make the pins thinner to facilitate the operate for fitting the pins in to the connecting plate, given that otherwise the fatigue strength is going to be lowered.
