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
• C4: Bearing internal clearance greater than C3

FAG NJ309-E-XL-M1-C4 is a single-row cylindrical roller bearing with a solid two-piece brass cage and C4 internal clearance (higher than C3), intended for applications with higher operating temperatures, greater shaft expansion, or tighter interference fits where standard clearance could become too tight 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 higher load capacity, longer service life, reduced heat generation, and improved speed capability compared to standard cylindrical roller bearings.

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
