248/1800CAF3/W33 Extra-Large Heavy-Duty Spherical Roller Bearing

The 248/1800CAF3/W33 is an extra-large, heavy-duty spherical roller bearing engineered for extreme radial load and severe operating conditions. Designed with a bore diameter of 1800 mm and an overall dimension of 2180 mm × 375 mm, this bearing is built to deliver high reliability, self-alignment capability, and exceptional durability in demanding industrial applications.

Key Features & Benefits

• Superior Load Capacity: Optimized for massive radial loads and moderate axial loads in both directions.
• Self-Aligning Design: Compensates for shaft misalignment up to 2°, reducing stress and prolonging service life.
• CA Design: Features a pressed steel cage and symmetrical barrel rollers for enhanced stability, lubrication flow, and higher load ratings.
• F3 Material Grade: Manufactured from case-hardened steel (e.g., G20CrNi2MoA) for superior impact resistance and fatigue strength—ideal for high-shock environments.
• W33 Lubrication: Includes lubrication grooves and three oil holes on the outer ring for efficient and consistent grease supply, essential in low-speed, high-load operations.

Typical Applications

This bearing is widely used in critical heavy machinery, including:

• Mining & Mineral Processing: Large ball mills, SAG mills, gyratory crushers
• Metallurgy: Heavy rolling mill stands
• Bulk Material Handling: Stackers, reclaimers, large crane slewing rings
• Cement & Power: Rotary kilns, large gearboxes
• Heavy Engineering: Tunnel boring machines, marine propulsion systems
