High power roller chains with improved fatigue strength and effect power
HI-PWR-S roller chains are enhanced in fatigue power and influence strength without modifying the dimension in the pin length direction of normal roller chains. Plates are enlarged, as well as the machining accuracy and assembling accuracy of components are improved. The roller chains hold substantial transmission efficiency for applications from very low to higher speeds and therefore are highly effective sufficient to stand up to long-term use.
Suggested makes use of
?Compared to common roller chains, HI-PWR-S roller chains are higher in optimum kilowatt rating by about 30 % in a medium to lower speed assortment. They exhibit exceptional capability in areas the place large shock loads are applied, drive units for regular start/stop, as well as in substantial speed applications.

?Civil engineering machines such as skid steer, trenchers, trucks, cranes, agitating trucks, forklifts and drive units for conveyors, elevators, stackers, and so forth.
Collection of chains
Generally, choose your chain with reference to “Designing of Chain Transmission” and in addition to your tables of “Drive Performance” and “Dimensions” of HI-PWR-S form roller chains.Nonetheless, only for a unique case of reduced speed and less shock, “Low-speed selection” can also be applicable.
HI-PWR-S Roller chains and ANSI typical chains are the same in simple dimensions. Use ANSI regular sprockets.
Connecting hyperlinks and offset links
Use H connecting backlinks for HI-PWR-S. In an H connecting link, the pins are lightly interference-fitted together with the connecting plate. For that connection among the connecting plate and also the connecting pins, spring pins are utilised as opposed to cotter pins for a common roller chain.
The center plates of an H connecting website link for multiplex chain has bushings pressed in.
HI-PWR-S roller chains usually do not have any offset hyperlink. Use an even number of links.
Never ever make the holes with the connecting plate larger and never ever make the pins thinner to facilitate the do the job for fitting the pins in to the connecting plate, since otherwise the fatigue strength is going to be lowered.
