Maquinaria Pioneer Bearing NCF2960V feature a combination of properties and capabilities unsurpassed by other maintenance-free bearings. The key to Maquinaria Pioneer AQ’s superior performance is its unique structure, composition and method of manufacture. Maquinaria Pioneer AQ30 and AQ100 Bearing NCF2960V are comprised of a bronze substrate and a bronze-lubricant inner structure. The bronze substrate provides a high load carrying capacity with excellent dimensional and structural rigidity. The bronze-lubricant inner structure supplies a permanent reservoir of lubricant for continuous restoration of the low friction Bearing NCF2960V surface.

Cast bronze alloys have been used for centuries in a broad spectrum of RODAMIENTOS DE RODILLO CILÍNDRICO COMPLETO NCF applications. Other Bearing NCF2960V materials have been unable to match their versatility. By alloying copper with other elements, the properties of bronze can be altered to suit the requirements of most any application. The choice of a bronze alloy for a particular application is determined by the desired physical, mechanical and metallurgical properties needed. For applications exposed to flowing water, corrosion resistance becomes a critical consideration. Corrosion associated with high water turbulence includes cavitations, erosion, and impingement attack. Pitting, galvanic, and crevice attack are other common forms of corrosion. The extent of corrosion attack depends on the Bearing NCF2960V environment and alloy composition. Oxygen and chlorine content, conductivity, water velocity, temperature, salinity, and biofouling affect rates of corrosion. Tensile strength, yield strength, fatigue strength, hardness, and grain refinement influence the ability of an alloy to withstand corrosion.

A wide selection of corrosion resistant alloys are available for underwater applications. Manganese bronzes are used extensively in fresh water applications, especially where toughness and shock resistance are necessary. Tin bronzes, which offer high resistance to impingement corrosion, and leaded tin bronzes, which provide good embedability and
tolerate greater shaft misalignment, are generally limited to low and moderate bearing loads. Aluminum bronzes, capable of much higher RODAMIENTOS DE RODILLO CILÍNDRICO COMPLETO NCF loads, are widely used in both fresh water and marine applications. Because seawater is an excellent electrolyte, severe galvanic corrosion often occurs when two dissimilar metals are coupled together. Aluminum bronzes provide high resistance to galvanic action, as very minor potentials are generated between aluminum bronze and Monel, Inconel, nickel or stainless steel. Most aluminum bronzes offer good resistance to creep, biofouling, cavitations, impingement corrosion and chemical attack.
