NJ306 ECM Cylindrical Roller Bearing 30x72x19mm with Brass Machined Cage Reinforced Design

The NJ306 ECM cylindrical roller bearing is a high-performance single-row roller bearing designed for applications requiring high radial load capacity and high-speed operation. The ECM brass machined cage offers superior wear resistance, excellent heat dissipation, and extended service life compared to standard pressed steel cages.

• Reinforced Internal Design: The E-suffix indicates an optimized roller and raceway geometry that increases dynamic load rating by approximately 15-20% over standard NJ306 bearings.
• Brass Machined Cage (M): Precision-machined from high-strength brass, providing exceptional dimensional stability and thermal resistance up to 200°C. Ideal for high-speed and high-temperature applications.
• Window-Type Cage: The C designation indicates a window-type cage design that guides on the rolling elements, reducing friction and improving lubrication distribution.

• Single Flange Inner Ring: Allows axial displacement of the shaft relative to the housing in one direction, accommodating thermal expansion while carrying radial loads.
• Double Flange Outer Ring: Provides axial guidance for the roller set, ensuring stable operation under combined loading conditions.
• Separable Design: Inner ring with roller and cage assembly can be mounted separately from the outer ring, simplifying installation and maintenance.

• Electric motors and generators
• Industrial gearboxes and transmissions
• Pump and compressor shafts
• Machine tool spindles
• Material handling equipment
• Automotive transmission systems
