SKF NU 211 ECP Series Roller Bearing, 55mm Inside Diameter, 100mm Outside Diameter - NU 211 ECP/C3

This roller bearing is a single-row cylindrical roller component designed to support radial loads in rotating assemblies. It incorporates shielding to limit contamination ingress and is intended for applications requiring controlled internal clearance and sustained rotational performance up to medium-high speeds.

Features and Benefits:

• Shielded design reduces particle ingress and lowers maintenance needs
• Cylindrical bore permits straightforward shaft fitting and axial displacement accommodation
• Non-metallic cage reduces friction and lowers operational noise
• C3 internal clearance compensates for thermal expansion during operation
• Dynamic capacity of 96.5 kN supports sustained load cycling
• Limiting speed of 8,000 r/min enables use in moderately high-speed machines

Applications

• Suitable for heavy-duty industrial rollers and conveyor shafts
• Ideal for electric motor and gearbox intermediate shafts
• Used with machine tool spindles requiring axial movement allowance
• Can be used for pump and compressor radial support
• Suitable for agricultural equipment main shaft bearings

What is the recommended operating clearance for temperature variation?

The bearing is supplied with C3 internal clearance to provide additional running clearance for thermal growth and preload adjustments.

How does the cage material affect lubrication intervals?

A non-metallic cage reduces wear on rolling elements and can modestly extend lubrication intervals by lowering internal friction.

What maximum radial load behaviour can be expected during cyclic operation?

The bearing has a dynamic load rating of 96.5 kN, indicating its capacity to endure repeated radial loading without premature fatigue.

How does sealing impact contamination control in harsh environments?

The shielded end configuration limits particulate ingress but is not a full seal, so it offers protection while permitting some lubricant migration.

Can the bearing accommodate axial displacement of the shaft?

Its cylindrical bore and single-row roller arrangement permit limited axial movement of the shaft relative to the housing.
