Since ASAP Stock Check has thousands of bearing products available for purchase, we have organized this catalog to help users navigate all subtypes we offer. To see a certain number or letter group in its entirety, just click on the “View All” button in its header or use the alphanumeric tabs at the top of the page. Take your time browsing, keeping in mind that every bearing name serves as a link to a curated list of part numbers.
The Multifaceted Uses of Bearings
Fundamentally, bearings are intended to reduce friction and facilitate controlled motion between different elements. Their configurations and sizes vary widely to accommodate distinct operating speeds, directional forces, thermal conditions, and other dynamics, with a single aircraft often relying on numerous bearing types for its subsystems. With this being said, bearings are broadly employed across:
Flight control surfaces
Engines and gearboxes
Landing gear assemblies
Environmental control units (ECUs)
Avionics and precision instruments
The Shared Traits of Aviation-Grade Bearings
Design Characteristics
Every bearing designed for aviation will feature:
High-Grade Materials: The underlying materials and surface coatings that a bearing uses are very dependent on the mechanical loads and outside stressors–like heat or moisture–that it will be subjected to. Still, they all need to resist deformation caused by repetitive motion and heat buildup from friction.
Rigid Tolerances: Durable materials are not enough to prevent wear if a bearing is not made correctly, so dimensions are carefully engineered and assembled to prevent excessive vibration and uneven load distribution.
Quality Standards
Regardless of what products they make, aerospace manufacturers are subject to strict oversight from aviation authorities. Put simply, the process starts with the entity obtaining design pre-approvals and getting their facilities certified to quality management standards like AS9100. From there, they are expected to continually abide by production and testing mandates to put out conforming products. For bearings specifically, manufacturers adhere to:
Material Compliance Rules: Raw materials and surface finishes must align with strict safety guidelines regarding their composition and purity. Depending on the end destination, they may also need to satisfy regional regulations like DFARS domestic melt restrictions for defense hardware in the United States and RoHS/REACH environmental safety standards.
Testing Protocols: Finished bearings have to be carefully assessed to make sure they have no defects, which can involve the use of coordinate measuring machines (CMM) to verify dimensions, non-destructive testing (NDT) methods to flag hard-to-spot material flaws, and dynamic torque testing to confirm low-friction performance.
Full Traceability: Documentation like Certificates of Conformance (CoCs), inspection records, and Material Test Reports (MTRs), along with unique facility and lot identifiers, accompany all aviation parts to prove their origin and airworthiness.
Procurement Considerations
To perfectly tailor a fulfillment strategy to a buyer’s specific needs or constraints from the start, distributors need a variety of important details. Ideally, you should be ready to state:
A complete part number and the associated manufacturer, as well as any other helpful identifiers.
The required quantity.
An ideal or firm delivery timeline.
Target part condition, whether that be Factory New (FN), New Surplus (NS), Overhauled (OH), or Serviceable (SV) units.
