SKF NU 2209 ECP Series Roller Bearing, 45mm Inside Diameter, 85mm Outside Diameter - NU 2209 ECP

This roller bearing is designed to support radial loads in rotating assemblies where a cylindrical inner fit is required and contamination protection is needed. It operates as a single-row element with shielded ends and is suited to applications demanding defined internal clearance and sustained rotational speeds.

Features and Benefits:

• Shielded ends reduce ingress and simplify maintenance
• Non-metallic cage lowers bearing noise and friction
• CN internal clearance accommodates thermal shaft growth
• Dynamic capacity of 85kN supports sustained radial loading
• Static capacity of 81.5kN resists deformation under standstill loads
• Limiting speed of 9500 r/min enables high-speed operation

Applications

• Suitable for industrial gearbox radial support
• Ideal for conveyor roller shafts in manufacturing
• Used with electric motor-driven rotating shafts
• Can be used for pump and fan radial bearings
• Suitable for machine tool intermediate supports

What bore type is required for mounting?

The inner bore is cylindrical so it requires a straight press or slip fit on a shaft.

How does the internal clearance affect shaft alignment?

The CN clearance provides moderate internal play to tolerate slight shaft misalignment and thermal expansion.

What cage material considerations affect lubricants?

The non-metallic cage is compatible with standard lubricants but may require assessment for speciality chemicals.

How should speed limitations be applied in design?

The limiting speed of 9500 r/min should be used as the maximum operational speed under recommended lubrication and load conditions.
