Substantial electrical power roller chains with improved fatigue strength and influence strength
HI-PWR-S roller chains are enhanced in fatigue power and effect strength devoid of shifting the dimension in the pin length direction of common roller chains. Plates are enlarged, as well as machining accuracy and assembling accuracy of elements are improved. The roller chains hold substantial transmission efficiency for applications from reduced to higher speeds and therefore are strong ample to stand up to long-term use.
Advisable uses
?In contrast to conventional roller chains, HI-PWR-S roller chains are increased in maximum kilowatt rating by about 30 percent in the medium to reduced speed range. They exhibit outstanding capability in spots wherever huge shock loads are applied, drive units for frequent start/stop, and in addition 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 forth.
Choice of chains
Normally, pick your chain with reference to “Designing of Chain Transmission” as well as to your tables of “Drive Performance” and “Dimensions” of HI-PWR-S type roller chains.However, only for a unique situation of very low velocity and much less shock, “Low-speed selection” can be applicable.
Sprockets
HI-PWR-S Roller chains and ANSI typical chains are the same in fundamental dimensions. Use ANSI standard sprockets.
Connecting backlinks and offset back links
Use H connecting backlinks for HI-PWR-S. In an H connecting hyperlink, the pins are lightly interference-fitted with the connecting plate. For the connection among the connecting plate and the connecting pins, spring pins are used as opposed to cotter pins for a conventional 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 website link. Use an even number of hyperlinks.
Never ever make the holes from the connecting plate greater and never make the pins thinner to facilitate the operate for fitting the pins to the connecting plate, given that otherwise the fatigue power will probably be lowered.
