Product Description
248/1000-B-MB-C4 is a Double Row Spherical Roller Bearing with central rib and cylindrical bore, dimensions 1000×1220×218 mm and weight 535 kg, replacing old designation 248/1000BMBC4. It features the B design with a fixed central rib for enhanced roller guidance, an MB solid brass cage guided on the inner ring, and C4 radial internal clearance. This bearing 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 6699901 N and a static load rating of 21599919 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.
