SKF Roller Bearing, 50mm Inside Diameter, 110mm Outside Diameter - NUP 310 ECP

This roller bearing provides rotational support for shafts in moderate to high-speed machinery, combining a single-row cylindrical bore design with protective sealing to limit contamination. It is intended for applications requiring a balance of static capacity and dynamic performance while operating at elevated rotational speeds.

Features and Benefits:

• Shielding reduces ingress while maintaining Compact assembly
• Non-metallic cage lowers operational noise and wear
• CN internal clearance ensures controlled axial play
• 127kN dynamic load capacity supports sustained operational loads
• 112kN static load capacity resists heavy stationary loads
• 8000 r/min limiting speed suits high-speed rotating equipment

Applications

• Suitable for conveyor drive shafts in manufacturing lines
• Ideal for pump shaft support under variable load
• Used with gearbox input shafts in industrial machinery
• Can be used for rotor support in electric motor assemblies
• Suitable for textile machine rollers requiring smooth rotation

What bore Interface does this bearing use for mounting?

It uses a cylindrical bore intended for slip-fit or adapter-sleeve installations.

How does the bearing manage axial clearance during assembly?

The CN internal clearance specification provides a standardised internal gap to accommodate thermal expansion and preload adjustments.

What operational limit should be observed for rotational speed?

The bearing is rated for a limiting speed of 8000 r/min under appropriate lubrication and load conditions.

How does the bearing cope with stationary loads when machinery is at rest?

Its static load capacity of 112kN is the maximum sustained radial load it can support without permanent deformation.

What materials influence friction and noise characteristics?

The non-metallic cage reduces internal friction and contributes to lower running noise compared with metallic cages.
