GGB has introduced its complete line of filament-wound plain bearings – GAR-FIL, GAR-MAX,
MLG and Multifil-- in Europe and Asia. These composite, bearings combine the self-lubricating properties of filled PTFE with a strong, stable structure to meet the high-load, low-wear requirements of wide variety of
applications.
These bearings employ a tough, high-strength composite structure consisting of epoxy-impregnated, wound glass fibers oriented to provide the radial and axial strength to support high loads. The natural lubricity of the bearing surfaces assures low friction in dry applications, making them particularly effective in applications where the relative motion is not sufficient to promote circulation of lubricants used with more conventional bearings.
Unlike many conventional non-metallic bearing materials, the high-strength composite structure of GGB filament-wound bearings offer a thermal expansion rate comparable to that of steel, assuring maximum dimensional stability and positive housing retention, even at elevated temperatures. Because absorption of moisture and swelling are negligible, they are also dimensionally stable in water.
GAR-FIL bearings offer one of the lowest coefficients of friction of any self-lubricating bearings under low-speed, high-pressure conditions. They also provide high rotational speed capability, good wear properties, resistance to chemicals and contamination, and machineable bearing surfaces for close tolerances. The bearings are used in valves, scissor lifts, pulleys, toggle linkages and other industrial applications.
GAR-MAX bearings provide high load capacity, good friction and wear properties, and excellent resistance to shock, contamination, chemicals and misalignment.
They are used extensively in steering linkages, hydraulic cylinder pivots, king pins, boom and scissor lifts, cranes, hoists, lift gates, backhoes, trenchers, skid steer loaders, front end loaders and other demanding applications.
MLG bearings are value-engineered for applications such as steering linkages, hydraulic cylinder pivots, king pins, boom and scissor lifts, cranes, hoists, lift gates, backhoes, trenchers, skid steer and front-end loaders and others. In addition to providing high load capacity and good friction and wear properties,
the bearings resist misalignment, shock and chemicals.
Multifil bearing material is designed for use in machine tool ways, gibs and other sliding applications. Easily bonded to any clean, rigid substrate, the material consists of PTFE and a proprietary filler, which deliver good performance in dry, oiled or greased conditions.
GGB filament-wound bearings are available in standard sizes from 12mm to 150mm ID, wall thicknesses of 2.5mm to 5mm and lengths of up to 400mm. Bearings with ID sizes from 10mm to over 500 mm with custom wall thicknesses and lengths are available on special order. Also available are special shapes based on customer requirements.
