Introduction
The Ingersoll Rand 47545145001 39218193 Motor Grease SHC220 combination brings together a major scheduled compressor-maintenance reference and the associated motor-lubrication component. The 47545145001 reference is associated with an 8,000-hour preventive maintenance package for the New Cobra M90–160 air-cooled configuration with modification, while 39218193 is identified as genuine Ingersoll Rand motor grease.
Electric motor bearings are critical to the reliable operation of a rotary screw compressor. They support the rotating shaft and must operate under continuous mechanical and thermal loads. Correct lubrication helps maintain a suitable friction environment and reduces direct metal-to-metal contact within the bearing system.
39218193 is particularly useful for maintenance planning because the reference is clearly identified by Ingersoll Rand as motor grease, while applicable parts catalogues describe it as Motor Grease SHC220. This provides a direct parts reference for service teams working with compatible compressor motor configurations.
Motor grease should not be confused with the compressor's primary lubricating fluid. The compressor air-end and motor bearings have different lubrication requirements, and using the wrong lubricant in either system can create unnecessary reliability risks.
Correct lubrication quantity is equally important. Too little grease may result in inadequate bearing lubrication, while excessive grease can increase churning and operating temperature. Ingersoll Rand motor documentation emphasizes controlled lubrication quantities and following the grease information specified for the individual motor.
Grease compatibility is another important consideration. Ingersoll Rand motor documentation warns that alternative greases can shorten motor life when incompatible lubricants are used. Where a motor has a dedicated grease nameplate, that specification should therefore take priority over a generalized assumption based only on compressor model.
The relationship between 47545145001 and 39218193 is useful during planned service because motor lubrication can be addressed alongside other major maintenance operations. The applicable maintenance package includes filtration and pressure-control components as well as motor grease, allowing maintenance teams to prepare the required service materials in advance.
For maintenance personnel, the grease should be applied according to the motor manufacturer's procedure. Before servicing, the technician should verify the motor grease specification, lubrication point, required quantity, and service interval. Existing grease condition and contamination should also be considered during inspection.
The 39218193 reference has also appeared in historical Ingersoll Rand compressor documentation alongside other motor-grease references. This reinforces the need to distinguish the specified grease from other lubricants that may look similar or carry comparable viscosity descriptions.
Exact package size, dimensions, weight, grease quantity per container, and current packaging configuration for 39218193 were not sufficiently verified from authoritative current documentation. These values are therefore intentionally not estimated.
For industrial compressor operators, the value of 39218193 lies in maintaining the motor lubrication system with a traceable Ingersoll Rand part reference. When the motor specification calls for the applicable SHC220 grease, using the correct lubricant and applying it at the correct interval supports bearing protection, stable motor operation, and longer-term compressor reliability.
