Product Description
248/1180CAFA/W20 is a Double Row Spherical Roller Bearing with dimensions 1180×1420×243 mm and weight 770 kg, replacing old designation 248/1180CAFA/W20. It features the CAFA internal design with symmetrical rollers, retaining flanges on the inner ring, and a guide ring centered on the inner ring. The bearing is equipped with an FA machined steel cage (outer ring centred) and W20 three lubrication holes in the outer ring. It is engineered for self-aligning capability, high load-bearing capacity, and impact resistance, making it ideal for applications with shaft deflection or installation errors. It offers a dynamic load rating of 7704900 N and a static load rating of 26994907 N.
The bearing operates in a temperature range of -30°C to +200°C. It provides stable and reliable shaft support under harsh, heavy-load conditions. It is widely used in metallurgy, mining, building materials industries, and other heavy industrial applications.
