Non-standard bearings are customized to meet specific user requirements in terms of size, material, or structure, overcoming the limitations of standard bearings. They are primarily used in the following scenarios:
1. High-end Manufacturing: Bearings in the aerospace industry, for example, must withstand extreme temperatures (-60°C to 300°C) and high-speed rotation (over 20,000 rpm). Non-standard designs can meet the lightweight requirements of titanium alloys or ceramic materials.
2. New Energy Equipment: Wind turbine main shaft bearings must withstand complex loads. Non-standard bearings achieve a lifespan of over 20 years through optimized roller arrangements (such as double-row tapered designs) (according to the 2023 Wind Energy Technology report).
3. Medical Equipment: Magnetic resonance imaging equipment requires non-magnetic, low-noise bearings. Non-standard bearings use stainless steel or engineering plastics, and their friction coefficient can be controlled below 0.001.
4. Automated Production Lines: Robotic spherical bearings require high precision (tolerance ±0.001mm) and repeatability. Non-standard solutions can reduce maintenance downtime by 90%.
