ADVANTAGES and APPLICATIONS. oilite SUPER oilite . Self-lubricating, highly wear-resistant, ductile, Self-lubricating, harder, higher strength and conformable and corrosion resistant. Large pore generally more economical than oilite bronze, but structure complete with complete alpha phase a lower speed rated bearing material for general bronze and twinning.

8 Most widely used of all oilite application. Recommended for high load bearing materials. applications at low speeds. Used in farm equipment, off-road equipment, winches, sheaves, conveyors, pulleys, etc. SUPER oilite 16. Self-lubricating. Similar metallurgically to Super oilite , but heat treated to a particle hardness greater than Rc50. High compressive strength for extreme load, low speed reciprocating and oscillating applications. Requires hardened steel shaft. Used in earth-moving equipment, cranes and hoists, Used in appliances, business machines, cylinders, railway brake rigging, presses, conveyors, etc. exercise apparatus, lawn and garden equipment, medical applications, material handling, packaging LOADS AND SPEEDS. and printing machines, and tools. The best method for evaluating the acceptability of oilite bearings for any given application is by using oilite PLUS PV factor (Pressure x Surface Velocity) where: The advantage of oilite Plus is realized in applications in which mixed-film, and boundary lubrication is P = the load in (psi) on the projected bearing area ( bearing ID x Length).
