SKF Roller Bearing, 40mm Inside Diameter, 80mm Outside Diameter - NUP 208 ECP/C3

This roller bearing is a single-row cylindrical roller bearing designed to support radial loads in rotating equipment within automation, electrical and mechanical systems. It features a cylindrical bore and shielded ends to protect rolling elements during operation while accommodating internal running clearances suited to slightly increased radial play.

Features & Benefits

• 62 kN dynamic load rating delivers high radial capacity
• 53 kN static load rating resists heavy stationary loads
• 11 000 r/min limiting speed enables high-speed usage
• Non-metallic cage reduces noise and low-friction operation
• C3 internal clearance permits thermal expansion under load
• Shielded end design minimises contamination ingress

Applications

• Suitable for high-speed motor spindles in automation equipment
• Ideal for drive rollers in conveyor assemblies
• Used with gearbox shafts subject to heavy radial loads
• Can be used for electrical machine rotor support
• Suitable for precision test rigs requiring defined clearance

What mass should installers expect when handling this item?

The bearing has a mass of 0.4kg, allowing straightforward manual fitting and handling.

Which seat and abutment dimensions are relevant for housing design?

Key abutment values include da min 47mm, db min 56mm and Da max 72.8mm for correct seating.

What are the reference and calculation parameters for life estimation?

Use a reference speed of 9 500 r/min and calculation factor kr 0.15 with fatigue limit Pu 6.7 kN for L10 assessments.

How does the internal geometry influence axial location?

The single-row NUP design permits axial locating on one side using a flange or shoulder while enabling shaft displacement on the opposite side.

Which corner radii must mating components respect?

Minimum fillet radii to mate with the races are r1,2 min 1.1mm and r3,4 min 1.1mm.
