The 452-575 is a Piper OEM landing gear bearing used in aircraft landing gear assemblies to support rotational movement and carry high mechanical loads during ground operations such as taxiing, takeoff, and landing.

In Piper aircraft applications, this bearing is specifically designed for use within the landing gear system, where it supports pivoting motion of gear components while maintaining alignment under significant static and dynamic loads. It helps ensure smooth extension/retraction (if applicable) and stable load transfer between structural components.

The bearing typically consists of precision-engineered rolling elements or a high-load plain bearing design, depending on the specific landing gear configuration. It is built to withstand shock loads from landings, vibration during taxi operations, and repeated cyclic loading throughout the aircraft’s service life.

Manufactured to Piper OEM specifications, the 452-575 is typically made from high-strength bearing steel or corrosion-resistant alloy materials, often with surface treatments to enhance wear resistance, fatigue life, and protection against corrosion in exposed landing gear environments.

Because it is part of the landing gear system, its condition is critical for safe operation. Excessive wear, rough rotation, or play can affect gear alignment, load distribution, and overall structural reliability.
