SKF NJ 209 ECP Series Roller Bearing, 45mm Inside Diameter, 85mm Outside Diameter - NJ 209 ECP

This roller bearing is a single-row cylindrical roller unit designed to support radial loads in industrial rotating equipment. It is suited to applications requiring a Compact radial bearing with a cylindrical bore and shielded ends, delivering consistent performance in automation, electrical and mechanical systems.

Features & Benefits

• Dynamic load capacity 69.5 kN for extended service life
• Static load rating 64 kN to resist high standstill loads
• Limiting speed 9,500 r/min for high-speed operations
• Non-metallic cage reduces friction and noise
• Internal clearance CN for controlled radial play

Applications

• Suitable for high-speed motor spindles in automation systems
• Ideal for gearbox radial load support in industrial drives
• Used with conveyor rollers in material handling equipment
• Can be used for rotating assemblies in electrical generators
• Suitable for precision machinery in electronics manufacturing

What mounting tolerance is recommended for the shaft seat?

Seat tolerances for standard conditions follow normal metric fits to ensure correct radial location and bearing performance.

How does the bearing behave under axial displacement?

The design permits axial movement relative to the housing when paired with appropriate companion rings or shoulders, accommodating thermal expansion.

What are the key obstructions to internal lubrication replenishment?

The shielded ends reduce direct ingress of contaminants and can limit lubricant escape, so re-lubrication intervals should be evaluated based on the operating environment.

What mass should be considered when specifying rotating assemblies?

The bearing mass is 0.44kg and should be included in rotor balance and inertia calculations.
