SKF Roller Bearing, 25mm Inside Diameter, 33mm Outside Diameter - NK 25/20

This roller bearing is a single-row needle bearing designed to support radial loads in Compact rotating assemblies within automation, electrical and mechanical systems. It features a parallel bore and an open-end configuration, and is suited to applications requiring high rotational capability and a narrow cross-section.

Features and Benefits:

• High dynamic capacity provides 19 kN load handling during operation
• Robust static resistance offers 32.5 kN support under stationary load
• Sheet-steel cage ensures controlled roller guidance and reduced friction
• Carbon-chrome steel rollers deliver durability and wear resistance
• Capable of 18,000 r/min for high-speed rotational tasks
• Grease and oil limits enable flexible lubrication options

Applications

• Suitable for precision actuator shafts in automation equipment
• Ideal for Compact gearbox input stages in electrical drives
• Used with sliding carriers in pick-and-place machinery
• Can be used for rotating contacts in small motor assemblies
• Used for conveyor rollers in light-duty material handling

What lubrication regimes are appropriate for prolonged operation?

For continuous high-speed use, oil lubrication up to 16,000 r/min is appropriate, while grease can be used for lower-speed or sealed installations up to 10,000 r/min

choose lubricant grade to match operating temperature and contamination levels.

How does the bore and end configuration affect mounting options?

The parallel bore simplifies press-fit installation and shaft alignment, while the open end permits direct shaft access for axial location with external retaining features.

What materials comprise the rolling elements and cage for maintenance considerations?

The rollers are MADE from carbon-chrome steel providing fatigue resistance, and the cage is formed from sheet steel, which permits routine inspection and replacement under maintenance schedules.

Can this bearing handle misalignment or radial shocks in assembly?

It is primarily intended for radial load support with limited tolerance to misalignment, heavy radial shocks or shaft deflection should be mitigated by design measures such as additional supports or compliant mounting.
