The Science Behind Polymer Bearings Plain
Material Composition and Properties
Polymer bearings plain are crafted from high-performance polymers, carefully selected for their exceptional properties. These materials often include polytetrafluoroethylene (PTFE), polyethylene (PE), and polyoxymethylene (POM). The unique molecular structure of these polymers allows for inherent lubrication properties, eliminating the need for external lubricants.
One of the key advantages of polymer bearings is their low friction coefficient, typically ranging from 0.03 to 0.25. This is significantly lower than traditional metal bearings, which can have friction coefficients up to 0.5 or higher. The reduced friction translates directly into improved efficiency and reduced wear on mating surfaces.
Self-Lubricating Mechanism
The self-lubricating nature of polymer bearings plain is a game-changer in many industries. This mechanism works through the transfer of a microscopically thin film of polymer material to the mating surface during operation. This transfer film acts as a lubricant, continuously replenishing itself as the bearing operates.
In some advanced polymer bearings, such as those offered by Wingold Bearing, the structure consists of a steel back with sintered porous bronze powder and modified polyformaldehyde (POM). This multi-layer design, complete with oil indentations, further enhances the self-lubricating properties and extends the bearing's service life.
Load Capacity and Durability
Despite their lightweight nature, polymer bearings plain can handle impressive loads. High-performance polymer bearings can withstand loads up to 140 MPa, making them suitable for a wide range of applications. The durability of these bearings is further enhanced by their resistance to chemicals, corrosion, and extreme temperatures, with some capable of operating in ranges from -40°C to +150°C.
