Look at PTFE Bushings for High Speed, High Temperature Applications

PTFE, is a popular choice for polymer bearings and bushings ,especially for applications involving high speeds and high temperatures.

PTFE Can Withstand High Temperatures

Virgin PTFE can continuously operate in temperatures up to 500°F, however, when operating at its maximum service tempature a loss of mechanical properties will occur. Proper design is necessary to avoid the negative impact in a specific application. The addition of additives (which will be discussed in a moment) can increase this to up to 550°F.

PTFE Can Perform in High PV Applications

There are high PV grades of PTFE that excel when used as bushings in applications with high speeds and higher loadings, including surface speeds up to 30 m/s.

PTFE is Not Chemically Reactive

This is another reason why PTFE is often the material of choice for high-performance bushings. High temperatures often mean aggressive chemicals, especially in industries like oil and gas. PTFE is the least chemically reactive polymer there is, and its kryptonite seems to be alkali metals like elemental sodium.

PTFE Has Extremely Low Friction

PTFE has the competitive coefficient of friction of any solid material in existence today with virgin PTFE’s coefficient of friction estimated to be between 0.05 and 0.10, making it an excellent choice for high performance bushing application. Low friction also means less buildup of heat, which in turn means less wear even under high speed and high temperature conditions. In addition, additives can be added to reduce friction even further.

PTFE Can Operate in Dry Running Conditions

PTFE bushings can do their job with no lubrication because PTFE is a self-lubricating polymer. This is a definite bonus for situations where lubrication either isn’t possible or isn’t recommended. It also offers extremely low breakout friction and stiction.

Inherent strength and flexibility ensure exceptional performance. Quality oil-free bushings and washers include multi-layer dry and flanged bushings. Leave a message for superior service and the latest technology.

PTFE bushings are ideal for high-speed and high-temperature applications. Their high temperature and speed capabilities, low friction, dry running, chemical resistance, and available additives make them a top choice for polymer bushings. Remember to consider PTFE for your next polymer bushing selection. They can operate without oil, handle high loads and speeds, maintain stable shape and dimensions, and feature thin-wall construction for compact equipment design.

They offer excellent wear resistance in conditions where oil film formation is challenging, such as with reciprocating and oscillating motion or frequent starts and stops. A wide range of standard parts like wrapped bushes, thrust washers, and slide plates are available. They are compatible with dry bearings and bush bearings.

1. A PTFE/Pb mixture (0.01~0.03mm) forms an initial transfer film that effectively coats the bearing assembly’s mating surface, creating an oxide-type solid lubricant film.

2. Sintered bronze powder (0.20-0.35mm) maximizes thermal conductivity away from the bearing surface and acts as a reservoir for the PTFE-lead mixture.

3. Low-carbon steel ensures high load capacity and excellent heat dissipation.

4. Copper/Tin plating (0.002mm) offers good corrosion resistance.
