 Features and advantages of QIBR outsourcing polyurethane bearings

QIBR outsourcing polyurethane bearings 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 bearings

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 bearings

Polyurethane bearings are widely used in the automotive sector, particularly in suspension systems, drive systems, and braking systems. Thanks to their vibration absorption, noise reduction, and durability, they are utilized in: 

Automotive wheel axles and suspension systems;

Engine and transmission components;

Wheels and braking systems.

2. Mechanical engineering

In mechanical engineering, polyurethane bearings are used in various high-load and wear-resistant machinery. Their elasticity and toughness allow them to operate under heavy loads and high-impact conditions.

3. Sports equipment

Polyurethane bearings are commonly found in sports equipment and tools requiring wear resistance and impact resistance, including:

Skateboards;

Snowboards;

Inline skates and other sports gear.

4. Aerospace industry

In aerospace applications, polyurethane bearings are favored for their excellent high-temperature and wear resistance. They are often used in aircraft components that endure high-speed operations and extreme environmental conditions.

5. Robotics and automation

Polyurethane bearings also find extensive use in robotics and automation equipment. They ensure high-precision, high-speed movements while reducing friction and noise, thus extending the equipment's lifespan.
