Oil-retaining Bimetallic Bearing Manufacturers

This metal composite self-lubricating bearing uses high-quality low-carbon steel as the base material, the middle layer is a sintered spherical porous copper powder layer, and the surface is a PTFE (polytetrafluoroethylene) based wear-resistant lubricating material as the bearing working layer. This material has excellent mechanical load-bearing performance. The copper powder layer can not only conduct the heat generated during the operation of the bearing in a timely manner, but also enhance the bonding strength between the plastic layer and the substrate.

PTFE material is designed for completely dry friction conditions, and a variety of derivative materials can be developed according to lubrication requirements, friction coefficients and durability requirements. The PTFE metal composite material developed by SNNOV can show excellent performance under various load, speed and temperature conditions, whether with or without external lubrication.

Oil-retaining Bimetallic Bearing Industry knowledge

What are the common faults of oil-lubricated bimetallic bearings?

Common faults of oil-lubricated bimetallic bearings mainly include the following:

Wear: Due to friction and load, the working surface of the bearing may wear, resulting in increased clearance and affecting its accuracy and performance.

Ablation: When lubrication is insufficient or the lubricant is of poor quality, ablation may occur on the bearing surface, causing melting and adhesion of metal materials, which may lead to bearing failure in severe cases.

Peeling: Due to material fatigue or chemical reaction, peeling may occur between the bimetallic layers, resulting in damage to the structural integrity of the bearing.

Overheating: Excessive load, poor lubrication or high ambient temperature can cause bearing overheating, which may cause material performance degradation or even failure.

Oil film rupture: Oil film rupture can lead to direct metal contact, increased friction and wear, and may eventually lead to bearing failure.

Contamination: External contaminants (such as dust, moisture or impurities) enter the bearing, causing lubricant contamination, affecting lubrication and accelerating wear.

Vibration: Due to imbalance or improper installation, the bearing may vibrate, and long-term vibration may cause fatigue damage or other structural problems.

Oil leakage: Poor bearing seal or lubrication system failure may cause lubricant leakage, affecting the lubrication effect.

Corrosion: If the lubricant is mixed with water or other corrosive media, it may cause corrosion of the bearing material and reduce its service life.

Fatigue cracks: Under long-term repeated loads, fatigue cracks may occur in the bearing material, leading to failure.

Preventive measures: To reduce the occurrence of these failures, the following measures can be taken:
Regularly check and replace the lubricant to ensure its quality.
Control the operating temperature to avoid overheating.
Perform regular maintenance and care to keep the bearing in good working condition.
Ensure correct installation and alignment to reduce vibration and imbalance.
