The key to solving the problem of bearing noise lies in reducing the vibration of bearings. By implementing targeted quality control during the grinding process of the inner ring raceway, it can indeed play a role in reducing the noise of the product.
Greetings from MTWB,a trusted supplier of precision bearings manufactured to international brand standards by 5 leading factories.
Bearings are the key components of electric motors. We understand that different industries – including household equipment, automotive, and aviation – have unique noise and vibration requirements for motor bearings.
Precision Grinding & Quality Control: Targeted control during inner ring raceway grinding reduces bearing vibration, ensuring low noise operation.
High-Precision Manufacturing: Our advanced machines refine every aspect of the bearing – raceways, balls, and cage – exceeding industry standards.
Sealing Performance: 100% inspection ensures effective sealing to prevent dust and debris ingress, maintaining long-term bearing efficiency.
Optimized Lubrication: Open bearings are pre-lubricated with anti-rust oil, closed bearings with lithium-based grease, and custom lubricants available upon request.
Noise & Vibration Testing: Bearings are classified by noise levels (Z1–Z4) and vibration levels (V1–V4), allowing customers to choose according to motor or application requirements.
