SKF Roller Bearing, 40mm Inside Diameter, 80mm Outside Diameter - NJ 2208 ECJ
This roller bearing is a single-row, shielded bearing designed to support radial loads in rotating machinery. It operates at high speeds and is suitable for installations requiring a cylindrical bore and a Compact race width, offering a balance of static and dynamic load capability for engineering applications.
Features and Benefits:
• Sheet-metal cage reduces mass and aids heat dissipation
• 81.5 kN dynamic rating supports sustained operational loads
• 75 kN static rating resists high stop-and-hold forces
• CN internal clearance allows controlled axial positioning
• Shielded end type limits contamination ingress at speed
• 81.5 kN dynamic rating supports sustained operational loads
• 75 kN static rating resists high stop-and-hold forces
• CN internal clearance allows controlled axial positioning
• Shielded end type limits contamination ingress at speed
Applications
• Suitable for high-speed spindles running at elevated r/min
• Ideal for shafts with a cylindrical-bore connection
• Used for rotating equipment needing Compact race width
• Can be used for radial-load carrying in motor assemblies
• Suitable for machinery requiring contamination-reduced bearings

• Suitable for machinery requiring contamination-reduced bearings
What bore type must the shaft provide for correct fitment?
A cylindrical bore is required to ensure the bearing locates correctly on the shaft.
How does the internal clearance classification affect assembly?
The CN clearance gives a nominal internal gap that assists controlled thermal expansion and axial displacement during operation.
What limitation does the bearing have regarding rotational speed?
The bearing is rated for operation up to 11,000 r/min, which defines the maximum permissible rotational speed.
How does the bearing cope with intermittent shock loads on standstill?
The 75 kN static load capacity specifies the maximum stationary load the bearing can withstand without permanent deformation.
What dimensional envelope should be considered for housing design?
The external diameter is 80 mm and the race width is 23 mm, which determine housing bore and axial space requirements.
