Design & Configuration

The 6008 Open comes as a standard, non-sealed bearing with a pressed steel cage. This configuration allows for flexible lubrication methods, making it suitable for applications where oil bath, oil circulation, or grease lubrication is already present in the system . For applications demanding protection against dust or moisture, the shielded (6008-ZZ) or sealed (6008-2RS) versions can be selected.

"A fundamental component for industrial drive systems and general machinery, the 6008 Open is chosen for applications where standardized dimensions, flexible lubrication, and reliable load capacity are essential for long-term operational performance."
