Aviation Bearing Parts and Components

View All

Aviation bearings control friction and support rotating, oscillating, or linear movement in aircraft equipment. Aircraft bearings may carry radial, axial, or combined loads.

Types of Aircraft and Aerospace Bearings

Common configurations include:

  • Ball bearings support high-speed rotation and carry radial and axial loads.
  • Roller bearings distribute loads across cylindrical or tapered rolling elements.
  • Needle bearings provide a compact option where radial space is limited.
  • Spherical and self-aligning bearings accommodate angular movement or misalignment.
  • Plain bearings and bushings support sliding or oscillating motion.
  • Rod-end bearings connect articulated flight-control or actuation mechanisms.
  • Thrust bearings primarily support loads acting along a shaft axis.

Depending on their design and specifications, aviation bearings may be used in aircraft engines, gearboxes, landing gear, flight-control systems, actuators, rotor systems, accessory drives, and other assemblies.

How to Identify an Aviation Bearing

Begin with the manufacturer part number. Preserve prefixes, suffixes, dashes, and revision characters because minor differences may indicate another configuration or specification. When available, confirm:

  • Manufacturer and CAGE Code.
  • NSN or NIIN.
  • Bearing type and dimensions.
  • Material and sealing configuration.
  • Internal clearance and load rating.
  • Speed and temperature range.
  • Lubrication requirements.
  • Aircraft or component applicability.

The aviation manufacturers directory can help identify the company associated with a bearing record. Similar dimensions or part numbers do not establish interchangeability. Verify eligibility against the applicable Illustrated Parts Catalog, component maintenance manual, drawing, or approved technical data.

Factors That Affect Bearing Selection

Bearing selection depends on more than bore diameter and outside dimensions. Selection may require evaluating radial and axial loading, rotational speed, temperature, vibration, contamination exposure, corrosion resistance, lubrication, and expected service life. Seals, shields, cages, race materials, and internal clearances can differ between similar bearings.

Request Aviation Bearing Availability

To request a quote, provide the exact bearing part number, manufacturer, quantity, required condition, delivery date, and documentation or traceability requirements. These details help ASAP Semiconductor identify appropriate procurement options. Catalog presence does not confirm current stock; availability, pricing, lead time, and condition are established during quotation.
