SKF NN 30 Series Roller Bearing, 45mm Inside Diameter, 75mm Outside Diameter - NN 3009 KTN/SP

This roller bearing is a tapered double-row component designed to carry combined loads in rotating assemblies, offering controlled internal clearance and a flanged outer race for axial location. It is intended for installations requiring a tapered bore and operates with either lubricant or grease at elevated rotational speeds.

Features and Benefits:

• C1 internal clearance reduces endplay for preload control
• Non-metallic cage lowers noise and reduces frictional losses
• Steel rollers provide high contact strength under load
• Flanged race assists in axial positioning during assembly
• 50.1 kN dynamic load rating supports sustained operational forces
• 65.5 kN static load rating resists heavy stationary loads

Applications

• Suitable for gearboxes requiring tapered bore mounting
• Ideal for wheelset or axle-end assemblies with axial loads
• Used with high-speed spindles operating on oil lubrication
• Can be used for shaft arrangements needing flange location
• Suitable for industrial rollers subjected to heavy static load

What bore contraction method does it require for mounting?

The inner bore is tapered at 1:12 and requires a matching taper sleeve or tapered shaft seating for correct fitting.

Which lubrication regime permits the highest rotational speed?

Operating with oil lubrication allows up to 14,000 r/min while grease-lubricated operation is limited to 12,000 r/min.

How does the bearing cope with stationary high loads?

Its static load capacity of 65.5 kN provides resistance to deformation under heavy non-rotating loads.

What cage and rolling-element materials affect thermal and wear behaviour?

The cage is non-metallic which reduces seizure risk at contact points and the rollers are steel to maintain rolling contact durability.

How does the outer geometry assist assembly alignment?

The outer ring incorporates a flange on the race to provide a positive axial locating face during installation.
