SKF NU 311 ECP Series Roller Bearing, 55mm Bore, 120mm Outside Diameter - NU 311 ECP/C3
This roller bearing is designed to support radial loads in rotating machinery where precise internal clearance and high load capacity are required. It accommodates a cylindrical shaft Interface and is constructed from steel with a non‑metallic cage, making it suitable for industrial shafts operating at elevated rotational speeds.
Features and Benefits:
• Single‑row design delivers high radial load capacity
• Internal clearance C3 allows increased thermal expansion tolerance
• Steel rollers and rings provide Durable rolling contact
• Non‑metallic cage reduces noise and frictional heat
• Limiting speed of 7000 rev/min supports high‑speed operation
• High static capacity of 143 kN resists heavy standstill loads
• Internal clearance C3 allows increased thermal expansion tolerance
• Steel rollers and rings provide Durable rolling contact
• Non‑metallic cage reduces noise and frictional heat
• Limiting speed of 7000 rev/min supports high‑speed operation
• High static capacity of 143 kN resists heavy standstill loads
Applications
• Suitable for heavy‑duty electric motor bearings
• Used for gearbox intermediate shaft support
• Ideal for conveyor drive rollers under load
• Can be used in pump rotor radial support
• Used with industrial fans operating at high speed

What bore Interface does this component require?
It requires a cylindrical bore with an internal diameter of 55 mm.
How does clearance classification affect mounting precision?
The C3 clearance provides extra internal radial play to compensate for shaft growth and misalignment during temperature rise.
What materials contact the shaft and housing during operation?
The rolling elements and raceways are MADE of steel, while the retaining cage is a non‑metallic material.
How should load expectations be assessed for stationary loads?
Use the static load rating of 143 kN to evaluate capacity against Peak non‑rotating loads.
What rotational limit should be observed during specification?
The bearing should not exceed a limiting speed of 7000 rev/min in service.
