Suffix / Series Meaning

• E: Increased load capacity
• XL: X-life (enhanced internal design for higher load ratings, longer service life, reduced heat generation, higher possible speeds)
• M1: Solid two-piece brass cage, roller-guided
• C3: Internal clearance larger than normal

FAG NJ309-E-XL-M1-C3 is a single-row cylindrical roller bearing with a solid two-piece brass cage and C3 internal clearance for applications where thermal expansion or tighter fits could reduce bearing clearance during operation. The NJ design functions as a support/semi-locating bearing, carrying axial load in one direction while allowing axial displacement in the opposite direction. The separable ring design simplifies installation. As an X-life bearing, it offers improved performance through optimized internal geometry and higher-quality components, supporting longer service life, higher load capacity, and reduced heat generation.

Typical Applications

Commonly used in:

• Gearboxes and transmissions
• Electric motors
• Pumps and compressors
• Agricultural and industrial machinery
• General equipment requiring high radial load capacity and controlled axial location in one direction
