Overview
The 856A2723G05 Machining Sleeve is a highly specialized piece of component repair tooling designed exclusively for the CFM56 engine family. It serves as a precision work-holding fixture for the No. 5 bearing outer race, allowing back-shop machinists and MRO technicians to perform authorized grinding, machining, or dimensional inspections safely and accurately.

Precision & Safety in Component Rework
The No. 5 bearing is critical for supporting the engine's rotor system, requiring extremely tight tolerances for roundness and concentricity. The bearing outer race is typically a thin-walled component; securing it with standard machine shop chucks can easily introduce mechanical distortion or "lobing" during the machining process. The 856A2723G05 processing sleeve envelops the outer race, providing uniform, 360-degree support. This eliminates radial distortion during high-precision repair schemes, ensuring the reworked component strictly adheres to OEM geometric specifications and performs flawlessly under engine operating loads.

Key Features & Benefits
• Distortion-Free Clamping: Provides uniform support to the thin-walled bearing race, preventing out-of-roundness issues during milling or grinding operations.
• CFM56 Specific Geometry: Machined to the exact dimensional tolerances required to cradle the No. 5 bearing outer race perfectly.
• Enables Deep MRO Repair: Essential for component repair shops executing approved repair schemes that require the reworking of engine bearing assemblies.
• High-Rigidity Construction: Manufactured from dimensionally stable, wear-resistant tool steel to maintain its own precision over years of continuous machine-shop use.
