The 55147 spacer is an aviation-grade hardware component used in aircraft engine and airframe assemblies to maintain precise spacing between mechanical parts. It ensures correct alignment, prevents direct metal-to-metal contact, and helps distribute loads evenly across bolted or fitted joints.

This type of spacer is commonly used in structural brackets, engine accessory mounting points, and control system assemblies where dimensional accuracy and vibration resistance are critical.

Key features include:

Aviation-grade precision spacer component
Maintains correct distance and alignment between parts
Prevents metal-to-metal contact and wear
Supports load distribution in bolted assemblies
Used in engine, airframe, and accessory installations (application dependent)
Manufactured from corrosion-resistant aerospace-grade materials
Designed for high vibration and cyclic load environments
Ensures stable mechanical geometry under operational stress
Compatible with certified aircraft maintenance and overhaul procedures
Used in structural, engine, and control system assemblies
