Bronze Thrust Washer With Graphite

As a commonly used component in mechanical systems, Bronze thrust washers are widely used in reciprocating rotary motion occasions in aerospace, automobiles, ships, and other fields. Its main function is to locate and avoid direct contact between parts, reduce the movement and wear of parts, and improve the stability of the system.

The wear resistance metal back with the solid lubricants can continuously provide a lubricating source during the washer operation to achieve the self-lubricating feature. This kind of washer can be applied under dry, high temperature, high pressure, corrosive, water, or other chemical environments when no oil can be introduced.

A bronze thrust washer is a material or combination of materials that is clamped between two separate joints (mainly flanges) and serves to maintain a seal between the two joints for predetermined service life.

The bronze thrust washer must be able to seal the joint surface and ensure that the sealing medium is impermeable and non-corrosive and able to withstand the effects of temperature and pressure.

A bronze thrust washer with graphite plugs provides both good wear resistance and a great self-lubricating feature of this washer.

This designation enables the thrust washer to be operated without oiling or greasing maintenance.
It is widely used in the field of high load and intermittent movement as well as oscillating movement conditions.

Types Of Bronze Thrust Washer

  1. Sinter Thrust Washer:Our SAE 841 Sintered Bronze thrust washer. They are rigid, temperature resistant and high strength parts formed through the process of sintering, or powder metallurgy. Powder metallurgy uses a number of different metals including aluminum, copper, nickel, brass, steel, stainless steel, nickel and titanium in the fabrication of powdered metal parts.
    Powdered metal parts have a proven record of unexcelled wear resistance and long life. They hold closer tolerances and can be made self-lubricating through oil impregnation. Because of smoother action and self-dampening features, powder metal assures a quiet operation.
  2. Plugged Graphite Bronze Thrust Washer: graphite bronze thrust washer, The wear resistance metal back with the solid lubricants can continuously provide lubricating source during the washer operation to achieve the self-lubricating feature.This kind of washer can be applied under dry,high temperature,high pressure,corrosive,water or other chemical environments when no oil can be introduced.

Elements Of Bronze Thrust Washer Selection

Temperature

The selected bronze thrust washer should have a reasonable service life at the maximum or minimum operating temperature, which varies greatly from one washer material to another.
In addition to the maximum and minimum operating temperatures that can be tolerated in the short term, its allowable continuous operating temperature should be considered. The thrust washer material should be able to resist creep in order to reduce the stress relaxation of the washer so that the oilless thrust washer can be sealed under working conditions. Most washer materials become severe with creep as the temperature rises, therefore, an important indicator of the quality of the washer is the creep relaxation performance of the gasket at a certain temperature.

Size

When meeting the flange roughness and unevenness conditions, choose as thin a thrust washer as possible. The thickness of the washer is related to its type, material, diameter, processing condition of the sealing surface, and sealing medium.

In addition, since bronze thrust washers are usually bolted to a flange, the bolts need to be preloaded during assembly to meet the sealing requirements, and since the thrust washer is a sealing element subject to many factors, controlling the preload is a very difficult problem. Various washers require different compression loads, and for special requirements of washer sealing, they do not have standard connection dimensions, such as flange thickness, bolt size, bolt spacing, etc., which require special design considerations.

Application

Mainly refers to the information of the connection system where the washer is located, it is necessary to choose the appropriate material and type of thrust washer according to the material of the flange, the type of sealing surface of the flange, the roughness of the flange and the information of the bolt.

Media

The thrust washer should be unaffected by the sealing medium under the whole working conditions, including high-temperature oxidation resistance, chemical corrosion resistance, solvent resistance, permeability resistance, etc. Obviously, the chemical corrosion resistance of the washer material to the medium is the primary condition for choosing the washer.

Pressure

Our thrust washer must be able to withstand a maximum pressure, perhaps a test pressure, which maybe 1.25 to 1.5 times the normal working pressure.
