SKF NA 4910.2RS Series Roller Bearing, 50mm Inside Diameter, 46.5kN Dynamic Load Rating - NA 4910.2RS

This roller bearing is a single-row component designed to support radial loads in rotating assemblies. It features a cylindrical bore and shielded ends to limit contamination ingress while permitting high-speed operation. Constructed from bearing steel with a sheet-metal cage, it is intended for industrial settings where compact, load-capable bearings are required.

Features and Benefits:

• 46.5 kN dynamic load delivers sustained operational capacity
• 69.5 kN static load resists deformation under heavy stands
• 3,400 r/min limiting speed permits high-speed rotation
• CN internal clearance reduces shaft-end float for precise fits
• Sheet-metal cage ensures controlled rolling-element guidance
• Shielded end design limits debris entry while allowing lubrication

Applications

• Suitable for conveyor rollers in manufacturing lines
• Ideal for gearbox support in medium-speed drives
• Used for idler shafts in material handling systems
• Can be used for pulley assemblies requiring shielded units
• Suitable for industrial motor supports needing high load capacity

What bore type does it accept for mounting?

It uses a cylindrical bore suitable for straight-shaft fits.

How does the end shielding affect maintenance intervals?

Shielded ends reduce contaminant ingress, extending lubrication periods between services.

What material gives the bearing its wear resistance?

Bearing steel provides the rolling elements and rings with hardness and fatigue strength.

How many rows of rollers are present and what is the effect?

There is one row of rollers which keeps the unit Compact while handling radial load.

What is the race width and how does it influence installation?

The race width is 23 mm, affecting axial space allocation within assemblies.
