24128/C4W33VA9B1 Spherical Roller Bearings, Stamping Steel Cage
The 24128/C4W33VA9B1 Spherical roller bearings are suitable for harsh environments involving high temperatures, low speeds, heavy loads, and moisture and oxide scale intrusion. Classic applications include the sector section of continuous casting machines, crystallizer vibration devices, cooling zone drive rollers, slab conveyor rollers, and guide rollers in rolling mill equipment.
The 24128/C4W33VA9B1 bearing is a Spherical roller bearings, double row with an inner diameter of 140 mm , an outer diameter of 225 mm, a width of 85 mm. High-carbon chromium steel rings, High-carbon chromium steel rolling mlement. its static radial rated load is approximately 1139836 N. It uses C4 standard radial clearance, Open type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
24128/C4W33VA9B1 bearings ( 140 mm x 225 mm x 85 mm) have the advantages of High temperature and water erosion resistant, impact resistant, automatically compensates for installation errors, long service life, and requires little maintenance., and are therefore widely used in the continuous casting machines.

The 24128/C4W33VA9B1 Spherical roller bearings mainly consist of an inner ring, an outer ring, spherical rollers, a cage, and seals. The outer ring raceway has a spherical structure, providing automatic self-aligning functionality. Some continuous casting machine-specific models employ a split design for easy installation and maintenance in hard-to-reach locations.
Spherical roller bearings possess extremely high load-bearing capacity, capable of withstanding heavy loads and impact loads. They also exhibit excellent self-aligning performance, compensating for shaft bending and installation misalignment. Furthermore, special wear-resistant and anti-peeling materials have been developed specifically for the harsh operating conditions of continuous casting machines, effectively extending their service life.
