TDI Two-Row Double Inner Race (Imperial)

The TDI (Two-Row Double Inner Race) (Imperial) tapered roller bearing features a double cone (inner race) and two single cups (outer races). Typically provided as a pre-set assembly with a spacer between the outer races, it is ideal for fixed-position shaft applications and is also suitable for rotating housing setups where axial float is required.

Overview of TDI Bearings

TDI (Two-Row Double Inner Race) (Imperial) tapered roller bearings are precision-engineered components comprising a one-piece double inner race (also known as a double cone) and two single outer races (cups). These bearings are commonly supplied as a pre-set assembly, including a spacer between the outer races to ensure correct internal clearance and simplify installation.

Design and Construction

Inner Race: One-piece double cone that maintains consistent alignment and provides high radial and axial load capacity.
Outer Races: Two single cups that allow for flexible mounting configurations.
Spacer: Typically included to maintain correct spacing between the outer races and ensure pre-adjusted internal clearance.

Performance Characteristics

TDI bearings are engineered to handle combined loads, particularly where radial and axial forces are present simultaneously. The robust design supports high load capacities and precise alignment under demanding operating conditions.

Typical Applications

TDI (Two-Row Double Inner Race) (Imperial) bearings are suitable for a variety of industrial applications, especially where axial space is limited and a compact bearing arrangement is preferred. Key use cases include:

Gearboxes
Construction equipment
Mining and aggregate processing
Industrial machinery

Mounting Considerations

TDI bearings are commonly mounted in a fixed position on the rotating shaft, providing precise axial location and high load capacity. When used with a rotating housing, the bearing can be set up to allow axial float, accommodating thermal expansion and dynamic misalignment without inducing stress on the bearing components.

Benefits of TDI Bearings

High radial and axial load capacity
Pre-set internal clearance for simplified installation
Compact design ideal for limited axial space
Versatile usage in both fixed and floating applications

Conclusion

TDI (Two-Row Double Inner Race) (Imperial) tapered roller bearings offer a reliable, high-performance solution for challenging industrial environments. Their integrated double cone and flexible mounting options make them a preferred choice for engineers and procurement professionals looking to optimize performance and reduce maintenance costs.
