– Choosing the Right Self-lubricating Bearing Bushing Material

Plain bearings are available in a wide variety of bushing materials.

Bushing materials include cast or machined metals, stabilized composite (“POM OR PTFE BUSH”), composite bearings, and combinations of different types of materials. Selecting the right bushing for each project requires detailed knowledge of the application requirements and experience with sliding bearings bushing technology.

Common failure forms of sliding bearings

Bearings can be divided into sliding bearings and rolling bearings. Most of the rolling bearings have been standardized, so they are widely used. But in the following scenarios, the main use of sliding bearings: running at high speeds, such as a turbo-engine
Special precision is required for the supporting position of the shaft, such as a precision grinder
Bear the huge impact and vibration load, such as rolling mill
Extra-heavy loads, such as hydro generators
Assembly requirements must be made into split bearings, such as crankshaft bearings
Bearings that operate under special conditions, such as those of a warship propeller
When radial dimensions are limited, as in a multi-roll mill

The failure forms of sliding bearings are particle wear, scratch, bite (gluing), fatigue spalling, and corrosion on the bearing surface; As well as cavitation erosion, electrical erosion, fluid erosion, and fretting wear failure forms.

Some of the hard particles into the bearing clearance rotate with the shaft, grinding the bearing surface.

When the instantaneous temperature rise is too high, the load is too large, the oil film is broken or the oil supply is insufficient, the surface material of the bearing will adhere and migrate, causing the bearing damage.

As solid bubbles form rapidly through the liquid and break on the solid surface, they wear away. Common in fluid pumps, Marine propeller blades, chemical agitators, and piping.

Mechanical wear caused by fluid erosion of the surface of a part (also possible with solid particles).

A form of wear caused by small vibrations between two surfaces (typical vibrations), ball bearings, needle bearings, and rollers
Bearings usually do not perform well under fretting conditions.

Under repeated loading, fatigue cracks appear on the bearing surface perpendicular to the sliding direction. Fatigue wear is common in the pump, compressor, and engine applications.
