Ingersoll Rand 47545139001 39218193 Motor Grease SHC220

Introduction

The Ingersoll Rand 47545139001 39218193 Motor Grease SHC220 combination brings together an 8,000-hour preventive maintenance reference and the specified motor grease used within the applicable service program. The current maintenance listing identifies 47545139001 for the New Cobra M90–160 water-cooled configuration with modification and specifies 39218193 Motor Grease SHC220 as one of its maintenance components.

Motor bearing lubrication is a small but important part of compressor reliability. Electric motors used in industrial rotary screw compressors operate under continuous mechanical and thermal loads, and their bearings depend on the correct lubricant to maintain a stable lubricating film and control friction.

39218193 is specifically identified as Ingersoll Rand motor grease. The SHC220 designation connects the maintenance reference with Mobilith SHC 220, a synthetic NLGI 2 grease based on ISO VG 220 synthetic fluid and a lithium-complex thickener. Mobil describes the product as suitable for demanding industrial applications and highlights its resistance to wear, rust, corrosion, and thermal degradation.

For compressor maintenance teams, the important distinction is that 39218193 is a motor grease, not a general compressor lubricant. The motor bearing and compressor air-end have different lubrication requirements, and selecting a lubricant simply because it is suitable for industrial machinery can create unnecessary compatibility or performance risks.

Lubricant selection becomes especially important when maintenance teams change grease brands or specifications. Mobil notes that Mobilith SHC Series products may be compatible with many mineral-oil-based products, but admixture can reduce performance, and recommends thorough cleaning before changing systems where maximum performance is required.

Ingersoll Rand motor-service documentation likewise emphasizes following the grease specification on the motor nameplate and warns that incompatible grease can shorten motor life. This makes the motor's individual lubrication instructions an important verification point even when the compressor maintenance package specifies 39218193.

Correct grease quantity is equally important. Adding too little lubricant can allow excessive bearing friction and wear, while over-greasing can raise operating temperature and interfere with normal bearing operation. Lubrication should therefore follow the specified amount and interval rather than being based solely on visual inspection.

The relationship between 47545139001 and 39218193 also helps streamline preventive-maintenance planning. The maintenance package brings together multiple service tasks, while 39218193 identifies the specific motor-lubrication material required for the applicable configuration. This makes the two references useful for purchasing, inventory management, and technician preparation.

Mobilith SHC 220 is designed for a broad range of demanding industrial applications. Mobil identifies it as a multi-purpose NLGI 2 extreme-pressure grease with an ISO VG 220 synthetic base fluid and a recommended operating range extending from approximately -40°C to 150°C, subject to the product's applicable specifications. These characteristics explain why the grease is suitable for demanding bearing environments, but they do not override the specific motor manufacturer's lubrication requirements.

Exact package size, dimensions, shipping weight, grease quantity per service, and packaging configuration for Ingersoll Rand 39218193 were not sufficiently verified from authoritative current documentation. These values should therefore be confirmed with the applicable parts documentation or supplier before purchase.

For industrial operators, the value of 39218193 is its clear identification as the motor grease reference associated with the applicable Ingersoll Rand maintenance program. When the compressor and motor configuration are correctly verified, using the specified lubricant helps support consistent bearing maintenance and long-term motor reliability.

Technical Specifications

The 39218193 product identity and its motor-grease designation are supported by Ingersoll Rand's parts listing, while Mobil confirms the technical characteristics of Mobilith SHC 220. Exact commercial package dimensions and weight are not sufficiently verified and should not be estimated.

Recommended Companion Models

These references address complementary filtration, air/oil separation, and pressure-control functions associated with the broader New Cobra M90–160 maintenance program. The published maintenance listing places these components within the applicable preventive-maintenance configuration.
