2. Snap ring (NR) - simplifies installation, ensures proper axial positioning in housings.

3. Factory pre-lubricated - maintenance-free operation with long service life.

4. Low friction - enables quiet, efficient, and stable performance.

5. Handles radial and limited axial loads - perfect for universal applications.

6. Durable construction - built for high-speed, continuous industrial operation.

Typical Applications

• Electric motors and drives

• Industrial machinery and automation

• Gearboxes and mechanical transmissions

• Pumps, compressors, and ventilators

• Agricultural and transport equipment

Comparison with Other Variants

• The 6009-ZZ version (metal shields) offers less protection against fine dust compared to 6009-2RS NR.

• The NR version eliminates the need for an additional retaining ring, simplifying the assembly process.
