Bearings are essential components in any mechanical system. They are used to support the shaft and control its movement, ensuring smooth operation. Without bearings, machines would not function properly. However, one of the most common issues users face is bearing overheating, which can significantly reduce the lifespan and performance of the bearing. So, what causes bearing heating? Here are some common reasons: 1. **Low oil level or oil leakage from the seal**: If the lubricant level is too low, the bearing may not be properly lubricated, leading to increased friction and heat. 2. **Overfilling with grease or oil**: Excessive lubrication can cause excessive churning, leading to higher temperatures and potential oil leakage. 3. **Dry or overly tight seals**: If the contact-type oil seal is too dry or the spring is too tight, it can increase friction and lead to overheating. 4. **Misalignment or deformation of the bearing housing**: If the inner hole of the housing is not round or the housing is deformed, it can cause uneven load distribution and heat buildup. 5. **Poor surface finish or incorrect dimensions**: A rough or uneven bearing surface, or an oversized housing bore, can also contribute to abnormal heating. It's important to regularly check and maintain your bearings to prevent such issues. Proper lubrication, correct installation, and regular inspection can help avoid overheating and extend the life of your equipment. If you're unsure about the condition of your bearings, it's always a good idea to consult with a professional or refer to technical manuals for guidance.

Irregular Window

Windows are optical glass with ground and polished faces that are relatively parallel.They are used to isolate two physical environments while allowing light to pass.Windows made of BK7 material have high transmission in the visible spectral region, do not scratch easily, do not degrade under normal operating environment and hence do not need any special precaution or treatment. Anti-Reflective Coating will provide higher transmission.
When selecting windows, you should consider the following: material,transmission,scattering,wave front distortion,parallelism and resistance to certain environment.
China Star Optics offers all types of windows made from different materials.Special size and materials are also available upon request.In addition, we provide a variety of single layer or multiplayer anti-reflecting coating on Optical Windows.
