Rated Working Loads / INSPIRETM SERIES SBR® The INSPIRE SERIESTM SBR® Treatment improves the rated working loads and horsepower capacities of roller chains used for power transmission applications. The improvements are included in the data presented in this catalog. Multiple strand chains are also improved (to a lesser extent) and therefore the increase in working loads are lower for these chains. Chains designed primarily for conveyor service (Double Pitch, and Attachment Chains) also bene t from the process. The working loads are not as high as the transmission chains because the design criteria for the attachment link is different and more suited to conveyor service. Note in the table to the left that the rated working load of the INSPIRETM SERIES SBR® is greater than our competitors Heavy ("H") Series. In some applications it may be possible to replace Heavy Series Chains with our standard product and HE Series (Through Hardened Pin) with our "E" Series. Signi cant cost savings can be realized in this case. Please contact Hitachi's product engineering personnel for more information. The table on the left is a general comparison of the ultimate strength ratings of different chain series. Contact Hitachi engineering personnel for additional information regarding chain selection for particular applications. 43
