SKF NJ 306 ECJ Series Roller Bearing, 30mm Inside Diameter, 72mm Outside Diameter - NJ 306 ECJ/C3
This roller bearing is designed to support radial loads in rotating machinery where cylindrical bores are used, providing controlled internal clearance for stable operation at elevated speeds.
Features and Benefits:
• Sheet-metal cage reduces mass and improves rotational balance
• Steel rollers deliver high contact strength for load transmission
• C3 internal clearance compensates for thermal expansion
• Single-row design simplifies mounting and axial alignment
• 12,000 r/min limiting speed enables high-speed operation
• Dynamic rating 58.5 kN sustains prolonged operational stresses
• Steel rollers deliver high contact strength for load transmission
• C3 internal clearance compensates for thermal expansion
• Single-row design simplifies mounting and axial alignment
• 12,000 r/min limiting speed enables high-speed operation
• Dynamic rating 58.5 kN sustains prolonged operational stresses
Applications
• Suitable for industrial gearboxes with cylindrical bores
• Used with motor shafts requiring high rotational speed
• Ideal for conveyor rollers under continuous load
• Can be used for machine-tool spindles with controlled clearance
• Appropriate for electric motor end supports in Compact assemblies

What material is used for the rolling elements?
The rollers are manufactured from steel to provide Durable contact surfaces.
How does the cage material affect maintenance intervals?
The sheet-metal cage offers dimensional stability that helps maintain lubrication pathways and can extend the time between inspections.
What internal clearance level is provided and why is it important?
It has C3 internal clearance which accommodates operational thermal growth and prevents preload during temperature rise.
What bore and outside diameters must the housing accept?
The component mounts on a 30 mm cylindrical bore and requires a housing that accommodates a 72 mm outside diameter.
What load capacities can be expected for static applications?
The static load capacity is 48 kN, suitable for withstanding heavy stationary forces during assembly or shock events.
