Metcar Block Bearings are ideally suited to the textile industry due to their inherent self-lubricating properties. Metcar Block Bearings are unexcelled when used as submerged bearings in textile applications such as dying, bleaching, sanforizing, mercerizing, washing and other wet processing operations. Metcar Block Bearings are low in friction, will not score the mating shaft, have high corrosion resistance and are extremely durable. Users report maintenance free operation with Metcar Bearings for periods up to 10 years. Special sizes up to 4-12" bore can be economically manufactured to meet your exact requirements.Completely self-lubricatingConstant and low coefficient of frictionUse dry or submergedOutstanding wear resistanceNo galling or seizing to shaftDimensionally stable (dry or submerged)Non-contaminatingOperates quietlyOther sizes available to meet your exact operating requirementsBearing assemblies available (see other pages)High corrosion resistance

For General Purpose Self-lubricating Applications up to 350F Operating Temperature (Dry or Submerged) Metcar 1010 Babbitt is an especially formulated self-lubricating bearing material low in friction, corrosion resistant, extremely durable and can be used for both dry and submerged application. The sizes listed are normally available from stock and have been sized to provide long bearing life under normal load and speed conditions, The dimensions shown will also provide proper bearing press fit in housings and correct shaft running clearance for operating temperatures up to 350F. Metcar Bearings can be manufactured in sizes up to 6" diameter shaft. Bearings sized to meet your exact operating conditions are available on short order.Completely self-lubricatingConstant and low coefficient of frictionUse dry or submergedOutstanding wear resistanceNo galling or seizing to shaftDimensionally stable (dry or submerged)Non-contaminatingOperates quietlyOther sizes available to meet your exact operating requirementsBearing assemblies available (see other pages)High corrosion resistance

Carbon-graphite bearings are used for running submerged in low viscosity liquids like water, gasoline, hot oil, solvents, strong chemicals, molten metals, and liquefied gases. Metallic bearings are often not satisfactory for these applications because the hydrodynamic film provided by these low viscosity liquids is not thick enough to overcome the strong atomic attraction between metal bearings and the metal shaft. Since there is no strong atomic attraction between carbon-graphite and a metal shaft, the thin hydrodynamic film provided by low viscosity liquids provides sufficient lubrication for carbon-graphite bearings. Carbon-graphite is also a self polishing, dimensionally stable material. If the shaft is polished to a fine surface finish, the shaft will polish the carbon-graphite material to the same fine, polished finish. When both the shaft and the bearing have this fine polished surface finish, a thin hydrodynamic film is sufficient to provide lubrication. Plastic or polymer bearing materials often fail in these submerged applications because of their tendencies to swell, soften or deteriorate. Metcar materials can handle all common chemicals except for a few extremely strong oxidizing agents such as hot, concentrated nitric acid.
