High power roller chains with improved fatigue strength and impact power
HI-PWR-S roller chains are enhanced in fatigue power and affect power without shifting the dimension in the pin length direction of regular roller chains. Plates are enlarged, and the machining accuracy and assembling accuracy of elements are improved. The roller chains hold large transmission efficiency for applications from reduced to higher speeds and are effective sufficient to withstand long-term use.
Advised makes use of
?Compared to regular roller chains, HI-PWR-S roller chains are increased in highest kilowatt rating by about 30 % in the medium to low velocity range. They exhibit fantastic capability in destinations in which big shock loads are applied, drive units for frequent start/stop, as well as in higher 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.
Variety of chains
On the whole, decide on your chain with reference to “Designing of Chain Transmission” and also towards the tables of “Drive Performance” and “Dimensions” of HI-PWR-S form roller chains.On the other hand, only for any special case of minimal velocity and less shock, “Low-speed selection” is additionally applicable.
Sprockets
HI-PWR-S Roller chains and ANSI conventional chains will be the very same in fundamental dimensions. Use ANSI normal sprockets.
Connecting hyperlinks and offset hyperlinks
Use H connecting backlinks for HI-PWR-S. In an H connecting link, the pins are lightly interference-fitted with the connecting plate. For the connection involving the connecting plate and the connecting pins, spring pins are used as opposed to cotter pins to get a common roller chain.
The center plates of an H connecting hyperlink for multiplex chain has bushings pressed in.
HI-PWR-S roller chains will not have any offset link. Use an even amount of backlinks.
By no means make the holes in the connecting plate more substantial and by no means make the pins thinner to facilitate the perform for fitting the pins in to the connecting plate, considering the fact that otherwise the fatigue strength is going to be lowered.
