Teflon bearings, also known as PTFE (polytetrafluoroethylene) bearings, are widely used in various industries due to their exceptional properties. They offer a unique combination of low friction, high wear resistance, and chemical inertness, making them ideal for demanding applications.
Teflon bearings are characterized by their:
These properties make Teflon bearings highly suitable for a variety of applications, including:
The use of Teflon bearings offers several advantages:
There are various types of Teflon bearings available, each designed for specific applications:
Bearing Type | Description | Applications |
---|---|---|
sleeve bearings: Cylindrical bearings that support radial loads. | Pumps, compressors, and other low-load applications. | |
flange bearings: Sleeve bearings with a flange for secure mounting. | Conveyors, printing presses, and other applications requiring bearing retention. | |
spherical bearings: Self-aligning bearings used in applications with misalignment or eccentric loads. | Robotics, machine tools, and other applications involving varying loads and movements. | |
thrust bearings: Designed to support axial (thrust) loads. | Pumps, turbines, and other applications with unidirectional loading. | |
linear bearings: Used for linear motion applications. | Machine tools, packaging equipment, and other applications requiring precise linear movement. |
Teflon bearings are typically made from virgin PTFE or filled PTFE. Virgin PTFE provides the highest level of wear resistance and chemical inertness, while filled PTFE offers improved strength and dimensional stability.
