Bearings & Components for Aircraft Maintenance, Repair & Overhaul (MRO)

Bearings & Components for Aircraft Maintenance, Repair & Overhaul (MRO)

Aircraft maintenance, repair and overhaul (MRO) involves inspecting, servicing, repairing, and replacing components to help maintain aircraft and associated systems in accordance with specified maintenance requirements.

Bearings, seals, O-rings, rod ends, spherical plain bearings, and engineering components can all form part of maintenance and repair activities across aircraft and aerospace equipment. Accurate component identification, condition assessment and correct specification are particularly important when replacing worn or damaged parts.

For aerospace applications, always confirm that replacement components meet the required specification, traceability, certification and approval requirements for the particular aircraft, system or application.


Components Used in Aircraft Maintenance, Repair & Overhaul

Bearings

Bearings are found throughout aircraft and aerospace equipment, supporting rotating and moving assemblies while reducing friction and maintaining controlled movement.

During maintenance, bearings may require inspection for wear, corrosion, contamination, excessive play, unusual noise or deterioration. Different applications can require specific bearing designs, materials, tolerances, clearances and lubrication arrangements.

When identifying a replacement, use the existing bearing reference, manufacturer information and accurate dimensions wherever possible.

Seals & O-Rings

Seals and O-rings are used throughout mechanical and fluid systems to retain lubrication or fluids and protect components against contamination.

Age, temperature, pressure, chemical exposure and operating conditions can contribute to seal deterioration. Inspecting for cracking, deformation, hardening, wear and leakage helps identify seals for replacement. 

Confirm correct dimensions, profile and material against the requirements of the original assembly.


Rod Ends & Spherical Plain Bearings

Rod end bearings and spherical plain bearings are used in assemblies requiring oscillating, angular or articulating movement.

During maintenance and overhaul, these components may be inspected for excessive clearance, corrosion, surface damage and other signs of deterioration. Correct identification is important because dimensions, thread configurations, materials and bearing specifications can vary considerably between applications.

Use the original component reference and relevant technical information when identifying a replacement.

Lubrication & Maintenance Products

Correct lubrication plays an important role in protecting bearings and other moving components against friction, wear and corrosion.

Different applications may require particular lubricant types, properties, and application methods. Follow existing maintenance documentation and manufacturer specifications when selecting and applying lubricants.

Cleaning, lubrication and appropriate maintenance products can also support component inspection and servicing procedures.

Supporting Aircraft Inspection & Component Replacement

Aircraft maintenance procedures can involve inspecting bearings, seals, rod ends, bushes, pins and other engineering components for signs of wear, corrosion, contamination, damage or excessive movement.

Where replacement is required, accurate identification is essential. Existing part numbers, manufacturer references, dimensions and technical specifications all help determine the required components.

Maintenance personnel should follow the applicable aircraft maintenance documentation and approved procedures when inspecting, removing or replacing components.

For aircraft and aerospace applications, always confirm component suitability, specification, traceability, certification and approval requirements against the relevant aircraft or system documentation before installation.
