A Brief History of NHI Idler Pulleys New Hampshire Industries, INC (NHI) was founded in 1960 to produce idler pulleys. Our "A" Series bearing was the key ingredient of the first idler pulleys produced. Today, we still build our "A" Series idlers using a combination of the time-tested design and continual improvement to ensure that our customers continue to have a cost-effective product. The "A" Series bearing was originally designed by the The "A" was joined by a "B" bearing, a design for heavier loads but lower speeds. The "B" was eventually supplanted by our "H" Series idler pulleys that exist today, utilizing standard ABEC-1 bearings such as the 6200, 6203, and 99502H to keep the heavier load capability while increasing the speed range. We also produce idlers using "plane" bearings. Starting in the early days of NHI (and continuing today) these oil-impregnated bronze bushings and powder metal steel bushings have been joined by the more recently developed PTFE lined sheet steel bushings for use in low speed, heavy load applications. Today, NHI manufactures idlers with stamped halves, fully machined, and from our split-formed steel technology. NHI has a long history of producing just the idler pulley that you need.
