SKF Roller Bearing, 55mm Inside Diameter, 120mm Outside Diameter - NU 311 ECP
This roller bearing is a single-row rolling element designed to support rotating shafts in industrial assemblies that require a sealed interface. It features end shields to limit contamination ingress and is suited to applications where radial load capacity and controlled internal clearance are important for stable operation.
Features and Benefits:
• Shielded ends reduce particulate ingress while maintaining rotation
• Non-metallic cage lowers running noise and reduces lubrication demand
• CN internal clearance ensures predictable axial displacement under load
• 143 kN static capacity resists deformation during standstill loads
• 156 kN dynamic capacity tolerates sustained radial forces in operation
• Limiting speed 7000 r/min permits use in moderately high-speed machinery
• Non-metallic cage lowers running noise and reduces lubrication demand
• CN internal clearance ensures predictable axial displacement under load
• 143 kN static capacity resists deformation during standstill loads
• 156 kN dynamic capacity tolerates sustained radial forces in operation
• Limiting speed 7000 r/min permits use in moderately high-speed machinery
Applications
• Suitable for conveyor drive-shaft support in manufacturing lines
• Ideal for gearbox input shafts in industrial transmissions
• Used with rotary presses requiring stable radial load handling
• Can be used for roller elements in material-handling equipment
• Suitable for electric motor accessory-shaft

What bore configuration does it require for mounting?
It fits a cylindrical bore and is intended for press or interference-fit installation.
How does the bearing manage axial movement under load?
The specified CN internal clearance provides a controlled allowance for axial and thermal movement during operation.
What cage material considerations affect maintenance intervals?
The non-metallic cage reduces susceptibility to fretting corrosion and can extend re-lubrication intervals compared with metallic cages.
How should rotational speed limits be interpreted for application design?
The limiting speed of 7000 r/min defines the maximum recommended rotational velocity to avoid excessive heat and wear during continuous use.
