388TD

Design Features of 388TD Bearing

388TD bearing features two tapered roller assemblies combined in a single cone, providing stable support for heavy radial and axial loads. 388TD double cone width is 2.094″. Its bore dia is 2.2651″. This design enhances load distribution, making it ideal for applications requiring precise alignment and durability.

 

What Benefits Can 388TD Bearing Provide?

  • High Load Capacity: It supports heavy radial and axial loads, making it suitable for demanding applications.
  • Improved Stability: The dual tapered rollers enhance balance and reduce deflection under load.
  • Durability: Its robust design ensures longer life and less maintenance.
  • Precise Alignment: The cone structure aids in accurate alignment, which reduces wear on machinery.

 

What Can 388TD Bearing Be Used for?

  • Automotive: Commonly found in wheel hubs, transmissions, and differentials for supporting heavy loads.
  • Industrial Machinery: Ideal for conveyor systems, gearboxes, and other equipment requiring high load capacity and stability.
  • Double Row Equipment: Used in heavy machinery like excavators and bulldozers to handle demanding conditions.
  • Mining Equipment: Suitable for harsh environments due to its durability and ability to support heavy radial and axial loads.
  • Aerospace: Utilized in landing gear and other components where precision and reliability are crucial.
