Product Description

The 248/1500BK30MB is an extra-large tapered bore spherical roller bearing designed for extreme heavy-duty applications. With a 1500mm bore diameter, it is widely used in steel mills, mining equipment, and large industrial machinery requiring high load capacity and reliable performance.

Key Features & Specifications

  • Tapered Bore Design (BK30MB): Provides secure shaft mounting with adapter or withdrawal sleeves for high torque transmission.
  • Extra-Large Load Capacity: Engineered to handle extreme radial and axial loads in heavy industrial environments.
  • Self-Aligning Capability: Compensates for shaft misalignment and deflection under harsh working conditions.
  • Machined Brass Cage: Ensures stable performance under low-speed and high-load operation.
  • Heavy-Duty Steel Construction: Manufactured from high-strength carburizing bearing steel for long service life.

Typical Applications

Steel rolling mills, mining crushers, cement rotary kilns, large gearboxes, and port machinery.
