SKF NU 305 ECP Series Roller Bearing, 25mm Inside Diameter, 62mm Outside Diameter - NU 305 ECP


This roller bearing is a single-row, shielded cylindrical bore component designed to support rotational assemblies operating at elevated speeds. It is intended for use where controlled internal clearance and non-metallic cage construction contribute to consistent performance within Compact assemblies.

Features and Benefits:


• Shielded design reduces contamination ingress and maintenance needs
• Non-metallic cage lowers operational noise and vibration
• CN internal clearance ensures predictable axial play under load
• High limiting speed of 15,000 r/min supports rapid-rotation applications
• Dynamic load capacity of 46.5 kN provides extended fatigue life

Applications


• Suitable for electric motor rotor support in high-speed drives
• Ideal for precision spindle systems requiring controlled clearance
• Used with industrial gearbox shafts operating at elevated rpm
• Can be used for automation equipment requiring low vibration
• Appropriate for centrifugal pump shafts in Compact housings

What axial movement can be expected under thermal variation?


The specified internal clearance class CN allows for limited and predictable axial displacement as temperatures change, helping maintain bearing function without excessive preload.

How does the cage material affect lubricant retention?


A non-metallic cage typically offers improved retention of lubricants at contact points, contributing to a steady lubrication film and reduced metal-to-metal contact.

What operating condition dictates the choice of a shielded end configuration?


Shielded ends are chosen when moderate protection against dust and particle ingress is required without significantly increasing friction compared with sealed arrangements.

How should the bearing be matched to shaft fit for optimum performance?


Select a cylindrical bore interference or transition fit based on shaft tolerance to control radial location while preserving the CN clearance for axial compensation.

Which load type is primarily supported by this bearing design?


The bearing is suited to accommodate substantial dynamic loads, reflected in its 46.5 kN dynamic rating, while also managing static loads up to 36.5 kN when stationary.
