The SKF deep groove ball bearing from the RS/GLE series is built to handle radial and axial loads in both directions. Its sealed design and special lubricant make it a practical choice for tough industrial settings. MR Industrial Accessories supplies this line to customers across the United States and Latin America. If you are replacing a worn bearing or need help selecting the right one, just send the part number via WhatsApp or email and our team will assist you.
The series designation uses two suffixes: RS and GLE. RS means the bearing has contact seals on both sides, which keep contaminants out and hold the lubricant in. GLE refers to a special factory grease, typically a high-performance lubricant for specific conditions. For example, in part number 6221-2RS1/GLE, the 6221 indicates the size and series, while the suffixes confirm the sealed and lubricated configuration. Understanding these codes helps you order the exact replacement.
These bearings are found in electric motors, centrifugal pumps, fans, conveyors and process machinery. Their ability to support combined loads and their sealing make them suitable for dusty, humid or moderately exposed environments. Industries such as food processing, chemical, petrochemical and manufacturing rely on them to keep operations running and reduce maintenance downtime.
When choosing a sealed bearing like this, consider operating speed, working temperature and load type. The RS seal provides an effective barrier but may limit maximum speed compared to open versions. The GLE lubrication is designed to last the bearing's service life under normal conditions, so relubrication is not required. During installation, ensure proper alignment and avoid impacts that could damage seals or raceways. Cleaning the shaft and housing thoroughly also helps extend component life.
Sealed deep groove ball bearings are made to international standards, so they are interchangeable between brands. However, suffixes can differ: other manufacturers may use 2RS, 2RSH or similar for contact seals, and special lubrication may have different codes. Always check critical dimensions and operating conditions before substituting one brand for another. If you are unsure, contact us with the original part number.
