Grease lubrication:
Grease lubrication is one of the commonly used lubrication methods for 608 2RS bearings. Its principle and application are relatively simple, but while providing effective lubrication, long-term stability and protection must also be taken into consideration.
1. Grease selection: In grease lubrication, choosing the appropriate bearing grease is crucial. Usually, bearing grease is composed of base oil and thickener. Different applications and working conditions require different types and brands of bearing grease. Common bearing greases include mineral oil-based grease, synthetic grease, etc., which have different properties such as high temperature resistance, low temperature resistance, and corrosion resistance.
2. Working principle of grease lubrication: Grease lubrication can form a uniform lubricating film when the bearing is running, reducing friction and wear, thereby extending the service life of the bearing. When the bearing rotates, the bearing grease will form a lubricating film on the friction surface, preventing direct metal contact and reducing friction loss and wear.
3. Sealing and anti-corrosion: Grease lubrication can also provide good sealing, prevent external impurities and moisture from entering the inside of the bearing, and protect the bearing from contamination and corrosion. This is crucial for the long-term stable operation of the bearing, especially in harsh working environments.
4. Maintenance and replenishment: Grease lubrication is relatively simple and does not require frequent maintenance. Under normal circumstances, you only need to check the lubrication of the bearings regularly and replenish or replace the grease as needed. This reduces maintenance costs and work downtime, and improves bearing reliability and stability.
5. Scope of application: Grease lubrication is suitable for a variety of applications, especially suitable for 608 2RS bearings under low speed, medium load and general working conditions. For example, household appliances, bicycles, rolling wheels, skateboards, etc. often use grease-lubricated 608 2RS bearings.

Oil lubrication:
Oil lubrication is another common 608 2RS bearing lubrication method. Compared with grease lubrication, oil lubrication has higher performance requirements and advantages in some specific applications.
1. Selection of lubricating oil: In oil lubrication, choosing the appropriate lubricating oil is crucial. The selection of lubricating oil usually depends on the working conditions of the bearing, speed requirements and environmental factors. Common lubricants include mineral oil, synthetic oil, grease, etc., which have different viscosities, temperature ranges and pressure resistance properties.
2. How oil lubrication works: Oil lubrication can provide lower friction and higher speed limits because the lubricating oil has better fluidity and can effectively lubricate the bearings during high-speed rotation. Compared with grease lubrication, oil lubrication has smaller friction losses and can reduce the temperature rise and energy loss of the bearing.
3. Maintenance and replacement: Oil lubrication requires regular maintenance and replacement of lubricating oil, because the lubricating oil will gradually lose, evaporate or become contaminated over time. Regular replacement of lubricating oil can keep the bearings in good lubrication condition and extend the service life of the bearings.
4. Scope of application: Oil lubrication is usually suitable for applications requiring high speed, high temperature and high precision, such as motors, fans, machine tool spindles, etc. In these applications, oil lubrication can provide better lubrication performance and stability, ensuring reliable operation of the bearings.
Oil lubrication is a high-performance lubrication method suitable for applications that require high bearing performance. Selecting the appropriate lubricant and regular maintenance can ensure the high-speed and stable operation and long-term reliability of the bearing.

608 Super wear-resistant and silent deep groove ball bearing
Deep groove ball bearings are widely used bearing type and are particularly versatile. They have low friction and are optimized for low noise and low vibration which enables high rotational speeds. They accommodate radial and axial loads in both directions, are easy to mount, and require less maintenance than other bearing types.
