Thrust Roller Bearings

Cylindrical thrust roller bearings

LYC’s cylindrical roller thrust bearings are available in single-row and double-row configurations.

  • Single-Row Thrust Bearings: Handle axial loads in one direction and limit axial movement in that direction.
  • Double-Row Thrust Bearings: Capable of carrying axial loads in both directions, effectively restricting axial displacement in both directions.
Applications:
  • Suitable for machinery that requires precise axial load support, such as gearboxes and industrial presses.

Thrust Roller Bearings

Taper roller thrust roller bearings

These bearings feature tapered raceways (inner and outer) and tapered rolling elements. The extension lines of these components intersect at a single point on the shaft axis, minimizing dynamic friction and enhancing performance.

Features:
  • Low Friction: The tapered design reduces dynamic friction, making it superior to other thrust roller bearing types.
  • No Angular Misalignment: These bearings do not tolerate angular errors between the axial components and the bearing housing.
Use Cases:
  • Ideal for thrust applications where axial loads are predominant, such as steering mechanisms and gear reducers.

Thrust Roller Bearings

Spherical roller thrust bearings

LYC’s spherical roller thrust bearings have spherical raceways on both the inner and outer rings, along with spherical rolling elements. This design allows for self-aligning capabilities, accommodating angular errors up to 2° to 3°.

Benefits:
  • Self-Alignment: Can adjust for minor angular misalignments.
  • High Load Capacity: Supports significant radial loads and a certain amount of axial load in one direction.
  • High-Speed Performance: Suitable for applications requiring both high load capacity and high-speed operation.
Applications:
  • Commonly found in hydropower turbines, pumps, and marine propulsion systems.
