The 452-366 is a Piper OEM aircraft bearing used in mechanical assemblies to support smooth rotational or oscillating movement while reducing friction and wear between moving components. It is designed to carry radial and/or axial loads depending on its installation within the aircraft system.

In Piper aircraft applications, bearings such as the 452-366 are commonly used in flight control systems, landing gear assemblies, stabilizer linkages, and airframe pivot points, depending on aircraft model configuration. Its primary function is to ensure precise alignment and low-resistance movement under load, contributing to consistent and reliable system performance.

The bearing typically consists of precision-machined inner and outer races with rolling elements (such as balls or rollers), or in some configurations a plain bearing design depending on application requirements. It is engineered to withstand vibration, cyclic loading, and environmental conditions typical in aviation operations.

Manufactured to Piper OEM specifications, the 452-366 is generally made from high-strength bearing steel or corrosion-resistant alloy materials, often with surface treatments that enhance wear resistance, reduce friction, and extend service life.

Because it is a load-bearing and movement-critical component, its condition is essential for safe operation. Wear, roughness, or excessive clearance can lead to increased friction, degraded control precision, or mechanical instability and must be addressed during maintenance.
