 Features and advantages of QIBR outsourcing polyurethane coated bearing with screw

QIBR outsourcing polyurethane coated bearing with screw addresses several critical issues in diverse fields, mainly in the following areas:

1. Double-row design

The bearings feature a double-row design, allowing for better load distribution and enhanced load-bearing capacity.

2. Vibration damping and noise reduction

With good elasticity and cushioning properties, these bearings effectively absorb vibrations and reduce noise levels.

3. Oil and chemical resistance

These bearings exhibit excellent resistance to oils, solvents, and various chemicals.

4. Impact resistance

The high elasticity of polyurethane provides excellent impact resistance, making the bearings suitable for working environments with shock loads.

Performance improvements and solutions for QIBR outsourcing polyurethane coated bearing with screw

1. Improving wear resistance

By adding reinforcing materials (e.g., carbon black, ceramics, metal powders), the hardness and wear resistance of polyurethane can be increased, ensuring stable performance under higher loads and prolonged usage conditions.

2. Enhancing oil and chemical resistance

Depending on the application environment, selecting polyurethane formulations with stronger resistance to chemicals and oils can extend the service life of bearings in challenging conditions.

3. Optimizing the thickness of the polyurethane layer

The thickness of the polyurethane layer directly affects the performance of the bearings. Appropriate thickness can improve impact resistance and wear resistance. However, excessive thickness might reduce the rigidity of the bearings, impacting performance. A well-designed polyurethane layer ensures a balance between shock absorption, wear resistance, load-bearing capacity, and operational stability.

4. Inner and outer race structure optimization

By optimizing the geometry and dimensions of the inner and outer races, the polyurethane layer can be subjected to uniform force distribution, avoiding localized excessive wear.

Main application areas of QIBR outsourcing polyurethane coated bearing with screw
