Higher power roller chains with improved fatigue strength and impact power
HI-PWR-S roller chains are enhanced in fatigue strength and influence strength with no modifying the dimension in the pin length path of conventional roller chains. Plates are enlarged, plus the machining accuracy and assembling accuracy of parts are enhanced. The roller chains hold higher transmission efficiency for applications from minimal to substantial speeds and therefore are impressive sufficient to withstand long-term use.
Encouraged employs
?Compared to conventional roller chains, HI-PWR-S roller chains are increased in maximum kilowatt rating by about thirty % within a medium to lower velocity selection. They exhibit superb capability in locations in which large shock loads are applied, drive units for frequent 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” as well as on the tables of “Drive Performance” and “Dimensions” of HI-PWR-S type roller chains.Even so, only to get a distinctive situation of minimal velocity and less shock, “Low-speed selection” can also be applicable.
Sprockets
HI-PWR-S Roller chains and ANSI typical chains will be the same in primary dimensions. Use ANSI standard sprockets.
Connecting backlinks and offset links
Use H connecting backlinks for HI-PWR-S. In an H connecting link, the pins are lightly interference-fitted with all the connecting plate. To the connection amongst the connecting plate as well as connecting pins, spring pins are utilised instead of cotter pins for any conventional roller chain.
The center plates of an H connecting link for multiplex chain has bushings pressed in.
HI-PWR-S roller chains do not have any offset link. Use an even variety of back links.
Hardly ever make the holes of the connecting plate larger and never ever make the pins thinner to facilitate the operate for fitting the pins into the connecting plate, since otherwise the fatigue power are going to be lowered.
