Polyurethane Coated Bearing With Screw

Features and advantages of QIBR polyurethane coated bearing with screw

The QIBR polyurethane coated bearing with screw solves several key issues across various fields, mainly reflected in the following aspects:

1. Wear resistance

The QIBR polyurethane coated bearing with screw has excellent wear resistance, which reduces wear over long-term operation and extends its service life, especially suitable for high-load or high-friction environments.

2. Shock absorption and noise reduction

The QIBR polyurethane coated bearing with screw has good elasticity and buffering properties, effectively absorbing vibrations and reducing noise.

3. Oil and chemical corrosion resistance

The QIBR polyurethane coated bearing with screw has good resistance to oils, solvents, and various chemicals.

4. Impact resistance

The high elasticity of the QIBR polyurethane coated bearing with screw gives it good impact resistance, making it suitable for environments with impact loads.

Performance improvements and solutions for QIBR polyurethane coated bearing with screw

1. Enhanced wear resistance

By adding reinforcing materials such as carbon black, ceramics, and metal powders, the hardness and wear resistance of polyurethane can be improved, enabling it to maintain stable performance under higher loads and long-term use.

2. Improved oil and chemical resistance

Depending on the bearing’s operating environment, polyurethane formulas with stronger chemical corrosion and oil resistance can be selected, improving the bearing's lifespan in chemical and oil-contaminated environments.

3. Optimization of polyurethane layer thickness

The thickness of the polyurethane layer directly affects the performance of the outsourcing polyurethane bearing. An appropriate thickness can improve the bearing's impact resistance and wear resistance. However, too thick a polyurethane layer may reduce the bearing's rigidity and affect performance. A reasonable design of the polyurethane layer thickness can meet the requirements for shock absorption and wear resistance while maintaining the bearing's load capacity and operational stability.

4. Inner and outer ring structure optimization

By optimizing the geometric shapes and dimensions of the inner and outer rings, the polyurethane layer can be evenly stressed, preventing local over-wear.
