Plastic bearing material mainly made of plastic. Their working principle is to support rotating parts through rolling friction.And the magnitude of the frictional force mainly depends on the manufacturing accuracy. Plastic rolling bearings, with their lightweight and corrosion-resistant characteristics.Are gradually replacing traditional metal bearings.Especially in fields such as precision instruments and new energy vehicles.
1. The following are its core features and application analysis:
A.Classification and Material Characteristics.
Classified by material.
POM plastic bearing material: high mechanical strength, good wear resistance, working temperature -60 ℃~100 ℃, suitable for precision scenarios.
Nylon bearings: Strong self-lubricating properties, low friction coefficient, temperature resistance up to 120 ℃.
PTFE plastic bearing material: with the lowest friction coefficient and outstanding high temperature resistance performance.
Structural characteristics of plastic bearing material
POM or PA is usually used as the inner and outer ring materials.And the cage is made of glass fiber reinforced nylon 66. The ball bearings can be made of glass, stainless steel, or ceramic materials.
Compared to metal bearings, it is 30% lighter in weight and has a smooth surface.That is less likely to absorb dust.
The main advantages of plastic bearing material
Lightweight and easy to install;
Corrosion resistance ensures stable operation in humid or corrosive environments;
Low friction coefficient reduces energy consumption;
Self lubricating characteristics reduce maintenance requirements.
In application scenarios, it is particularly suitable for harsh environments such as mechanical trimming or concrete pipe cutting machines.Which can withstand vibration and high loads; It is also widely used in the fields of food and medical equipment to achieve low-speed heavy-duty operation.
Installation requirements: Apply pressure evenly to avoid damage caused by direct impact.
Fit tolerance: Static fit or dynamic fit should be selected according to the load type, as excessive interference will affect the rotation accuracy.
