Product Description
NNCF4988V is a 440 series double row full complement cylindrical roller bearing with dimensions of 600 × 160 × NNCF4988V mm. The bearing is commonly cross referenced with NNCF49 and is designed to accommodate extremely high radial loads while providing axial guidance in locating bearing arrangements.
Its full complement roller design maximizes load carrying capacity and rigidity, making it suitable for heavy-duty gearboxes, mining machinery and metallurgical equipment.
Key Features
- Double row full complement roller design for maximum radial load capacity.
- Capable of accommodating heavy radial loads and moderate axial loads.
- High rigidity and excellent resistance to shock loading.
- Integral flange design provides axial guidance for locating bearing positions.
- Optimized internal geometry for long service life under demanding operating conditions.
Applications
- Industrial gearboxes
- Rolling mills
- Mining machinery
- Metallurgical equipment
- Material handling systems
