Product Description
FC88130355 is a Four-Row Cylindrical Roller Bearings with dimensions of 440×650×355 mm. It is engineered to accommodate extremely high radial loads and is widely used in large rolling mills, steel production lines, heavy metallurgical equipment, and other ultra-heavy-duty industrial machinery.
As a large-size rolling mill bearing, this model is designed for demanding operating conditions involving heavy loads, shock loads, and long production cycles. Its robust internal structure helps improve equipment reliability and service life.
Key Features
- FC type four-row cylindrical roller bearing designed for rolling mill roll neck applications.
- Four-row roller arrangement provides exceptionally high radial load carrying capacity.
- Separable design allows convenient mounting, dismounting, and maintenance.
- High rigidity construction helps maintain rolling accuracy under heavy operating loads.
- Optimized for high-speed rolling mill operation with reduced friction and heat generation.
- Suitable for medium-to-large rolling mill stands operating under continuous production conditions.
- Large-size bearing configuration developed for heavy plate mills, hot strip mills, and other ultra-heavy rolling equipment.
- Enhanced structural rigidity improves resistance to shock loads and rolling force fluctuations.
- Designed for demanding steel production environments requiring maximum reliability and service life.
