Oil-Rite Corporation is known throughout the world for its high standard of manufacturing and innovative design in lubrication equipment. Founded in 1933 by Frank J. Lyden, the original product line consisted of constant level oilers used in conjunction with large bearings and gear boxes. The range of product expanded rapidly in the following decades to include not only lubricators, but liquid level and flow monitoring equipment. Oil-Rite manufactures 90 percent of components using its in-house work centers. Engineering and R&D are singularly dedicated to this industry, improvement in product and processes, and the next innovation in lubrication equipment.
