Do deep groove ball bearings require a specific lubricant?

Deep groove ball bearings do require the use of specific lubricants to ensure their good operational performance and extend their service life. Here are several key points for lubricant selection:
1. Select lubricant type based on application environment
Lubricating grease: suitable for most medium to low speed, sealing or maintenance inconvenient occasions, such as household appliances, electric tools, etc., with good adhesion and sealing properties.
Lubricating oil: suitable for high-speed or high-temperature environments, with good cooling performance, commonly used in precision machinery, high-speed motors, etc.

2. Consider the working temperature range
Different lubricants adapt to different temperature ranges. For example, lubricants with low viscosity and low starting torque should be selected in low-temperature environments; In high-temperature environments, lubricants with strong antioxidant properties and low volatility should be selected.

3. Reference bearing speed
Low viscosity lubricating oil or specialized high-speed grease should be used during high-speed operation to reduce friction and heat generation; At low speeds, a lubricant with slightly higher viscosity can be selected to enhance the lubrication film.

4. Matching bearing capacity with working conditions
If deep groove ball bearings need to withstand large loads or impacts, it is recommended to use reinforced grease, such as grease containing molybdenum disulfide or polyurea based grease.

5. Cleanliness and compatibility requirements
For industries with high cleaning requirements such as food processing and medical equipment, food grade lubricants that meet NSF H1 standards should be selected.
When replacing lubricants, attention should also be paid to the chemical compatibility of new and old lubricants to avoid mixing and causing a decrease in lubrication effect or reaction deterioration.

6. Service life and maintenance frequency
Long life grease is suitable for closed systems and difficult to maintain situations, and can effectively extend the maintenance free period of bearings.
Some special applications, such as high-speed machine tool spindles, require regular replenishment or replacement of lubricants to ensure continuous and stable operation.
