High electrical power roller chains with enhanced fatigue strength and affect power
HI-PWR-S roller chains are enhanced in fatigue power and impact power devoid of modifying the dimension while in the pin length direction of regular roller chains. Plates are enlarged, as well as the machining accuracy and assembling accuracy of components are improved. The roller chains hold high transmission efficiency for applications from minimal to substantial speeds and are highly effective ample to stand up to long-term use.
Recommended employs
?Compared to standard roller chains, HI-PWR-S roller chains are greater in optimum kilowatt rating by about 30 % in the medium to very low speed variety. They exhibit exceptional capability in destinations the place big shock loads are applied, drive units for frequent start/stop, and also 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.
Selection of chains
In general, select your chain with reference to “Designing of Chain Transmission” and also to your tables of “Drive Performance” and “Dimensions” of HI-PWR-S form roller chains.Having said that, only to get a distinctive situation of very low speed and less shock, “Low-speed selection” can be applicable.
Sprockets
HI-PWR-S Roller chains and ANSI normal chains will be the identical in fundamental dimensions. Use ANSI regular sprockets.
Connecting back links and offset hyperlinks
Use H connecting links for HI-PWR-S. In an H connecting website link, the pins are lightly interference-fitted using the connecting plate. For your connection between the connecting plate and the connecting pins, spring pins are made use of as an alternative 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 do not have any offset website link. Use an even number of back links.
Hardly ever make the holes in the connecting plate larger and never make the pins thinner to facilitate the do the job for fitting the pins into the connecting plate, because otherwise the fatigue power will be lowered.
