Thrust washer bearings by Viiplus

Thrust washers can be found in almost every appliance, machine, transportation conveyance, power tool, and recreational device that has moving parts, axles, bolts, pins, bearings, and rotating components. In their simplest form, thrust washers are long-wearing flat bearings in the shape of a washer that transmit and resolve axial forces in rotating mechanisms to keep components aligned along a shaft. Thrust washers are an economical alternative to rolling thrust bearings whenever forces velocities are moderate.

What is a Thrust Washer Bearing?

Thrust washer bearings are flat bearings that are typically inserted between a rotating component and a stationary component, and function to keep the rotating component in place by providing it with something to rub up against if it begins to move laterally. They support the axial load or side-to-side motion on a shaft. Viiplus thrust washer bearings are made from self-lubricating materials that promote maintenance-free, dry operation for a wide range of applications and axial load requirements.

Oilless Thrust Washer Bearing Applications – Bearing Uses | Viiplus

Graphite thrust washer bearings are mostly used for sliding bearings, which are divided into radial bearings and thrust bearings.
Viiplus oilless thrust washer bearing use graphite materials as the main base material and are used in the bearings of conveyors, dryers, textile machines, submersible pump motors, etc. Pollution, while the graphite bearing has strong self-lubrication and corrosion resistance, and can operate for a long time without using lubricating oil.

Applications: Marine pumps, valves, bearings, bushings, piston rings, steam fittings, and gears.

C90700 (SAE 65) Tin Bronze is primarily a gear bronze. It is strengthened by the solid solution of tin in the copper. This results in a strong, hard intercrystalline phase rich in tin. The tin atoms distort the copper matrix enough to help inhibit slip of crystal layers and the intercrystalline phase contributes to hardness. The tin bronzes do develop a low friction deposit of bronze on the mating steel parts. For this reason, tin bronze is the alloy of choice for nonferrous gears. Conforms to continuous cast specification ASTM B505
