Introduction
The Ingersoll Rand 47545144001 39218193 Motor Grease is a maintenance-oriented lubricant reference for compatible compressor motor applications. Ingersoll Rand officially identifies 39218193 as a genuine motor-grease spare part, making the reference useful for maintenance teams seeking a traceable lubricant specification.
For electric compressor motors, correct bearing lubrication is an important part of long-term reliability. Bearings operate under continuous rotational loads, and the selected grease must provide appropriate consistency, viscosity, load capability, and temperature performance for the specific motor. Using the specified lubricant helps maintenance personnel avoid unnecessary variation in bearing service practices.
The 39218193 reference is associated with Mobilith SHC 220 in applicable Ingersoll Rand documentation. Mobil describes SHC 220 as an NLGI 2 extreme-pressure grease based on synthetic oil and a lithium-complex thickener. Its ISO VG 220 base-oil viscosity provides the characteristics required for a broad range of heavy-duty industrial lubrication applications.
Mobilith SHC 220 is also designed for demanding temperature conditions, with a published recommended operating range of approximately -40°C to 150°C. The synthetic formulation provides low-temperature pumpability, structural stability, adhesion, and resistance to water, while the additive system supports protection against wear, rust, and corrosion.
The relationship between 47545144001 and 39218193 should nevertheless be treated as application-specific. The 47545144001 number represents a maintenance reference, while 39218193 identifies the individual grease product. Available evidence does not establish a complete package bill of materials proving that 39218193 is included in every 47545144001 package. Buyers should therefore confirm the current parts documentation before assuming package contents.
Correct grease quantity is just as important as grease selection. Under-lubrication can reduce bearing protection, while excessive grease can generate heat and impair bearing performance. Maintenance personnel should follow the compressor and motor manufacturer's specified lubrication quantity and interval rather than relying on a generic greasing schedule.
For industrial purchasing, the 39218193 reference provides clear part-number traceability and a defined lubricant identity. This is particularly valuable when multiple greases are used across a compressor fleet, since motor grease should not be confused with airend coolant, oil-filter components, or other service lubricants.
Before installation, the equipment model, motor frequency, bearing arrangement, lubricant specification, and service procedure should be verified. Ingersoll Rand recommends using its parts-selection resources to identify the correct OEM components for the specific equipment configuration.
