  • Self-lubricating bearings

    A self-lubricating sintered bearing is a metallic component with high porosity (20-25% in volume), impregnated in a lubricant oil. The oil contained in the porosity provides a constant lubrication between bearing and shaft, so the system does not need any additional external lubricant. Self-lubrication allows this type of sliding bearing to work under hydrodynamic conditions, resulting in a very low friction coefficient.

    AMES manufactures three ranges of self-lubricating bearings, as follows:
    1. Selfoil® standard bearings. Bearings made in standard dimensions, with spherical or cylindrical shapes, with or without flange. Selfoil® is the best solution for retail, and is available off the shelf.
    2. Selfoil® Rods for machining. These bearings are solid or hollow cylinders, to be machined to final dimensions when the system is not ready for standard Selfoil® bearings.
    3. Bearings by design. Customized bearings for medium- to high production volumes, specifically designed for a given equipment. Most of AMES bearing production corresponds to this range of OEM bearings.

  • Filters and porous metallic components

    Filters and porous metallic components are sintered metallic parts with high porosity, between 35 and 80% in volume, typically made of Bronze 89/11 or Stainless Steel 316L.

    Filters and porous metallic components have some particular characteristics:
    - The mean pore pitch is variable, from 2 µm to 210 µm.
    - Their behaviour is very regular, because of the rigorous classification of the raw material particle size.
    - They are depth filters, with thickness ? 1.5 mm, i.e., the fluid is obliged to follow a winding patch in order to exit the filter, so its filtering efficiency is very high.
    - They can work at high temperature and high pressure, without deformation.
    - Their chemical resistance is good, specially if material is stainless steel.
    - They are weldable and machinable, so they can be adapted to specific assemblies.
    - Their robustness make its cleaning easy, so they are reusable.

    AMES offers the following range of filters and sintered porous components:
    - Filters and porous components of Bronze. They are made of spherical particles of Bronze 89/11. The mean pore pitch is variable from 8 µm up to 210 µm, and also its thickness. AMES offers two standard products inside this range:
    - Standard Bronfil® Discs, of standard dimensions, with diameter from 4 to 28 mm, and length from 3 to 15 mm.
    - Standard Bronfil® Silencers, of standard dimensions, with the thread integrated in the silencer.
    - Filters and porous components of Stainless Steel. They are made of Stainless Steel 316L. They are manufactured by compacting stainless steel powder in a rigid tool under high pressure. They have high corrosion resistance, and they resist elevated working temperatures (up to 800ºC). The mean pore pitch is variable, from 2 µm up to 16 µm.
    AMES also offers the Filters CIP inside this range of product. They are cylindrical filters of small wall thickness and high length, made by isostatic compacting. They are used as cartridge filters for high flow. They work under the same requirement as a conventional stainless steel filter. The mean pore pitch is variable, from 2 µm up to 100 µm.

  • Mechanical and hydraulic parts

    The equipment goods industry is a major user of sintered components. Since the profitability of purchased sintered parts increases with the annual output, it is easily understood that the largest users of sintered components are in the automotive, household appliances, handtools, and some other industries of high volume.

    As a reference, each car uses some 12 kg of sintered parts in Europe. Taking an average weight per piece of about 20 grams, the result is that each car contains about 600 sintered components, some of them considered as Critical or as Safety components.

    Sintering is used for a large number of structural components, either mechanical or hydraulic. There is a great diversity of materials (iron based), shapes, finishings, treatments and coatings, whick make possible to reach components of high precision and strong performance.
    Material for such components is typically steel. AMES provides a wide range of sintered steel grades, from Fe-C, to high-alloy steels with Cu, Ni, Mo, Cr or Mn.
    Properties of materials are the result of the combination of the alloying strategy and the processing technology. The achievable properties are, indicatively: yield strength higher than 850 MPa, tensile strength higher than 1250 MPa, apparent hardness up to 55 HRC, and bending fatigue limit higher than 450 MPa. These properties are comparable to wrought structural steels or to alloyed cast iron.

    AMES has developed two materials for special or generic applications:
    - Simoloy-B®. This a low-cost steel, suitable for mechanical applications of medium-high strength. It is recyclable, nickel-free, and has low sensibility to price variations of the alloying elements.
    < - TriboPM®. This is a metallic based composite material, suitable for applications where high wear resistance combined with low friction coefficient is required.

  • Gears

    Sintering successfully achieves the geometry of the teeth directly from the compacting operation. Furthermore, it allows to obtain gears with a large variety of sizes and shapes (straight, double, helical) as well as of steel with different degrees of alloying, finishings with heat treatment or special coatings, or stainless steel based.

    Within this product range, the AMES Tamarite plant is specialized in the manufacture of gears of small size, using as base the sinter-hardening steel, which provides very high hardness at the sintering furnace without needing any further hardening treatment.

    Depending on the required accuracies and shape, it is possible to apply secondary machining operations to finish the component, although it is not usual.


  • AMES develops a new material for self-lubricating sintered bearings that provides low friction coefficient at low cost.

    The Powder Metallurgy industry continues to innovate in one of its longest established products: the Self-Lubricating Bearings.
    AMES, an european leader in production of self-lubricating sintered bearings, has developed a new range of bearings called Ames-LFC®. The innovative material, a double-layer type, consist in a low-cost base material and a tribological layer, keeping intact the open porosity througout inner diameter and assuring then the oil feed. The result is a material better than Bronze for initial and stady-state friction coefficient (lower than 0,01), lower material cost, and similar corrosion resistance. Durability of the Ames-LFC® bearings is very high, resisting more than 10.000 hours in endurance tests with stable friction coefficient and without significant wear.
    The main applications of the Ames-LFC® bearings are in equipment requiring low electrical current consumption and/or low noise, and in equipment working in start-stop conditions, where the initial friction coefficient must be minimized. Typical examples are electric motors for automotive industry (fans, sunroofs, mirrors, starters), brakes, motors for domestic appliances, and other specific industrial sectors.
