AI Overview
The 315189 A (or BC4-0103) is a four-row cylindrical roller bearing, commonly designated as 4R3232, specifically engineered for high-load steel rolling mill applications. With dimensions of
(bore) x
(OD) x
(width), these bearings handle immense radial loads and are often used on roll necks, requiring separate thrust bearings for axial loads.
Key Features and Specifications:
- Dimensions: (Inner Diameter/Bore) x(Outer Diameter) x(Width).
- Design: Four-row cylindrical roller bearing (often FC type) featuring high radial load capacity.
- Material: High-quality bearing steel, commonly with a brass cage for high-temperature and harsh, high-speed rolling conditions.
- Application: Primarily used in steel mill roll necks, rollers, and metal processing machinery.
- Interchange: 315189 A is commonly replaced by or equivalent to SKF's BC4-0103.
Usage in Rolling Mills:
- High Load Support: Designed specifically to handle the extreme radial pressures found in backup and work rolls.
- Mounting: Generally mounted with an interference fit on the roll neck and used with separate bearings for axial support.
- Maintenance: EAZ heaters are frequently used for safe mounting/dismounting to prevent damage to the bearing or shaft.
