WS22207-E1-2RSR Sealed Spherical Roller Bearings, Lip Seals On Both Sides, For Continuous Casting Machines
The WS22207-E1-2RSR 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 WS22207-E1-2RSR bearing is a Sealed Spherical Roller Bearings, lip seals on both sides with an inner diameter of 35 mm , an outer diameter of 72 mm, a width of 28 mm. GCr15, GCr15SiMn, SUJ2 rings, GCr15, SUJ2 rolling mlement. Its dynamic radial rated load is approximately 88830 N, its static radial rated load is approximately 80821 N. It uses CN standard radial clearance, 2RSR = Seals on both sides, normal temperature type, together determine its load-bearing capacity, rotational accuracy, and applicable working conditions.
WS22207-E1-2RSR bearings ( 35 mm x 72 mm x 28 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 WS22207-E1-2RSR 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.
