Genuine Joy/Ingersoll Rand MSG Centrifugal Compressor Rotating Assembly
Overall Summary
This listing is for a high-value, mission-critical Rotating Assembly Group for a Joy/Ingersoll Rand MSG Centrifugal Compressor (Model TA50HZ, Serial# X0-6956). This comprehensive asset includes multiple stages of precision-engineered rotor assemblies (S1, S2, and S3) and a complete installation kit. These components were professionally repaired and refurbished by Ingersoll Rand (the OEM successor to Joy Mfg. Co.) in late 2024 and early 2025. This is a rare opportunity to acquire a "zero-hour" refurbished rotating group for a large-scale industrial centrifugal compressor at a significant discount from the OEM replacement cost.
