2. Aplicaciones detalladas
This tapered roller bearing is engineered for heavy-duty rolling mill machinery, including:
- Hot/Cold Rolling Mills: Handles axial/radial loads in steel plate shaping.
- Continuous Casting Lines: Ensures stability in high-temperature environments.
- Metal Processing: Supports high-speed rotation in wire rod production.
3. Casos prácticos del sector
Scenario 1: Steel Plate Rolling
In a 1,200-ton rolling mill, the Bdl 32217 operates under 180°C conditions, reducing downtime by 40% compared to standard bearings.
Scenario 2: Aluminum Foil Production
Used in tandem mills for ultra-thin foil (0.005mm), achieving micron-level thickness consistency.
