Product Description
SL1818/1120 is a single row full complement cylindrical roller bearing with dimensions of 1120 × 1360 × 106 mm. The bearing is commonly cross referenced with NCF18/1120V and is designed for applications requiring extremely high radial load capacity, high rigidity and long service life.
With a bore diameter of 1120 mm, this bearing is particularly suitable for rolling mill main drives, large mining installations and ultra-heavy industrial machinery.
Key Features
- Full complement roller design without cage for maximum radial load capacity.
- Higher load carrying capability than comparable caged cylindrical roller bearings.
- High rigidity and excellent resistance to shock and vibration loads.
- Optimized internal geometry for reliable load distribution and extended service life.
- Designed for ultra-large industrial equipment operating under extremely heavy loads.
Applications
- Rolling mill main drives
- Large metallurgical machinery
- Mining installations
- Heavy industrial transmission systems
- Custom engineered machinery
What is a full complement cylindrical roller bearing?
A full complement cylindrical roller bearing uses the maximum possible number of rollers without a cage, providing significantly higher radial load capacity than comparable caged designs.
What is the equivalent bearing for SL1818/1120?
SL1818/1120 is commonly cross referenced with NCF18/1120V bearing.
What industries commonly use SL1818/1120?
SL1818/1120 is commonly used in rolling mills, steel plants, mining machinery and other heavy industrial equipment requiring extremely high radial load capacity.
Can SL1818/1120 be supplied with customized clearance or tolerance classes?
Yes. Large-size full complement cylindrical roller bearings can be manufactured with customized internal clearance, tolerance grades and lubrication arrangements according to application requirements.
