Product Description
248/1250B.MB.C3 is a large double-row spherical roller bearing with a 1250 mm bore and boundary dimensions of 1250×1500×250 mm. With a weight of approximately 890 kg, it is designed for large-scale machinery requiring high load capacity, self-aligning capability and robust operation under demanding conditions.
The bearing features a B design with a fixed central rib for effective roller guidance and an MB solid brass cage guided on the inner ring. The C3 radial internal clearance provides additional allowance for thermal expansion and demanding heavy-load operating conditions.
With a basic dynamic load rating of 8999.806 kN and a basic static load rating of 30499.823 kN, the 248/1250B.MB.C3 is suitable for heavy industrial equipment operating under high loads, shock and vibration, including machinery used in metallurgy, mining, cement and building materials processing.
Key Features
- Large double-row spherical roller bearing with self-aligning capability to accommodate shaft deflection and housing misalignment.
- B design with a fixed central rib for effective roller guidance and high load-carrying capacity.
- MB solid brass cage guided on the inner ring for robust operation under demanding loads and vibration.
- C3 radial internal clearance provides additional allowance for thermal expansion and heavy-duty operating conditions.
- High radial load capacity and strong resistance to shock and vibration for demanding industrial equipment.
- 1250 mm bore and 890 kg weight make it suitable for large-scale heavy industrial machinery.
- Designed for demanding applications in metallurgy, mining, building materials and other heavy industries.
