uxcell Flanged Bearing 4mmx10mmx4mm Deep Groove Bearings

Our products offer exceptional performance and durability. Let's dive into the key features:

1. Chromium Steel (GCr15) Bearings: These bearings boast high hardness, excellent wear resistance, low noise, and extended service life.
2. 440C Stainless Steel Bearings: Crafted from high-quality stainless steel, these bearings are ideal for use in corrosive environments and non-lubricated, highly oxidizing atmospheres.
3. Single-Row, Pre-Lubricated Design: These bearings are primarily designed to accommodate radial loads, making them suitable for a wide range of industrial equipment, small rotary motors, office machines, power tools, lawnmowers, tractors, and more.
4. Diverse Size Options: We offer a variety of bearing types in different sizes, allowing you to select the perfect fit for your specific needs.

Now, let's address some key considerations regarding bearing lubrication:

1. Determining the Need for Lubrication: Lubricating bearings is based on their working conditions. If you notice abnormal noise, deteriorated grease, or increased friction, it's recommended to replace the grease or lubricant. However, if the current lubricant is performing well, there may be no need for additional lubrication.
2. Typical Lubrication Amount: Proper bearing lubrication is crucial, as it plays a vital role in reducing friction. The internal bearing space is typically filled with grease ranging from 20% to 40%. In smaller or miniature bearings, the grease fill can be as little as 10%. Excessive grease can raise the temperature inside the bearing, decreasing the lubricant's effectiveness.
3. Important Considerations: Both over-lubrication and under-lubrication can lead to premature bearing failure. Before operating at full speed, a running-in period is required to allow the grease to settle properly. Maintaining cleanliness in the bearing and its working environment is crucial, as even small, invisible dust can have a detrimental effect.

In summary, our bearings offer superior performance and durability, thanks to the use of high-quality materials and precise manufacturing. When it comes to lubrication, it's essential to monitor the condition and maintain the optimal grease fill to ensure the longevity and reliable operation of your equipment.
