⚙️ Design & Meaning of “TD”

• TD suffix: Indicates a double inner race with tapered bore
• Built as a double-row cone, meaning:
  • Higher load capacity than single-row designs
  • Handles combined radial + axial loads efficiently

This geometry is typical of tapered roller bearings, which are specifically designed to support both radial and thrust loads in heavy-duty applications.

🏭 Typical Applications

This type of bearing is usually found in:

• Heavy industrial gearboxes
• Mining and construction equipment
• Rolling mills
• Large axle or shaft assemblies

The double-row configuration makes it ideal for high-load, high-impact environments.
