    • Commonly used in automotive transmissions and machine tools

  2. Cylindrical Roller Thrust Bearings

    • Provide high load-carrying capacity

    • Suitable for heavy machinery and industrial applications

  3. Spherical Roller Thrust Bearings

    • Designed for misalignment correction and heavy loads

    • Used in turbines, gearboxes, and marine applications

  4. Tapered Roller Thrust Bearings

    • Ideal for applications requiring high thrust capacity and precision

    • Common in automotive differentials and construction equipment

  5. Needle Roller Thrust Bearings

    • Compact design with high load capacity

    • Used in automotive and aerospace industries

Applications of Thrust Bearings

Thrust bearings are essential in various industries, including:

  • Automotive Industry: Used in gearboxes, clutches, and transmissions

  • Industrial Machinery: Essential for pumps, compressors, and heavy-duty equipment

  • Aerospace Industry: Found in aircraft engines, landing gear, and propulsion systems

  • Marine Applications: Used in ship propellers and steering mechanisms
