Spi led pixel light can get the matrix light, led video wall, flexible led screen effect with our different dimension from 30mm up to 120mm with different pixel space. We have the 20mm matrix light, 30mm matrix light, 50mm matrix light. All of them use the SMD RGB 5050 led lamps. Of course, the led matrix can be made with other color SMD led lamps. You can use them to make the indoor video mall or outdoor video wall displays. What's more, the led matrix lights are also for the signs, such as decorations for building outline, amusement part, outdoor billboard, LOGO, square and street, stage, hotel, bar and disco, etc.

If you've ever used NSK bearings, you might have noticed some unusual noise during operation. This can be frustrating, especially when it's unclear why the noise is happening. In this article, we'll explore the common causes of noise in NSK bearings and provide practical solutions to help reduce or eliminate it.
1. **Bearing Damage or Scratches**
One of the main reasons for noise in NSK bearings is physical damage, such as scratches or dents on the raceways or rolling elements. These imperfections can cause vibrations and unwanted sounds during rotation. To prevent this, ensure that the bearing is properly installed without tilting, avoid excessive impact during transportation, and use high-viscosity grease to protect against wear and rust.
2. **Inappropriate Lubrication**
Improper lubrication is another common cause of noise in NSK bearings. This can happen if the lubricant is old, contaminated, or not sufficient for the application. There are three main issues related to lubrication: faulty lubricant, insufficient lubrication, and aged or hardened lubricant. Always choose a suitable lubricant based on the bearing type and operating conditions. Regularly check and replenish the lubricant as needed, and replace it before it degrades.
3. **Dust and Contamination**
Dust and foreign particles entering the bearing can lead to noise and premature failure. To address this, make sure all mating parts—such as the shaft, housing, and bearing itself—are thoroughly cleaned before assembly. Use high-quality lubricants free from contaminants and consider improving the bearing seal to prevent dust ingress. Avoid using plastic materials that may contain impurities or embedded foreign objects.
By following these maintenance and installation practices, you can significantly reduce the chances of noise in NSK bearings and extend their service life. Proper handling, regular inspection, and correct lubrication are key to ensuring smooth and quiet operation.
