The Ingersoll Rand 47642703001 39218193 Motor-Bearing Grease combines an extended preventive-maintenance reference with a dedicated motor lubrication component. 47642703001 is identified as an 8,000-hour air-cooled preventive maintenance kit for older Cobra M132-160 screw compressors, while 39218193 corresponds to Mobilith SHC 220 for applicable motor-bearing lubrication.
Motor bearings operate under continuous mechanical load and require the correct lubricant to maintain reliable operation. Proper grease selection helps reduce friction and wear while protecting bearing surfaces against corrosion and lubricant degradation.
Mobilith SHC 220 is a synthetic NLGI 2 lithium-complex grease with ISO VG 220 base-oil viscosity. Mobil describes the product as suitable for demanding industrial applications and highlights its adhesion, structural stability, wear protection, rust protection, and corrosion resistance.
For applicable Ingersoll Rand compressor motors, 39218193 is specifically associated with 60 Hz motor lubrication. This distinction is important because Ingersoll Rand service documentation also specifies different greases for certain other motor configurations. The motor grease nameplate should therefore always be treated as the primary reference when determining the correct lubricant.
The relationship between 47642703001 and 39218193 should be interpreted as a maintenance reference rather than proof of package contents. The preventive-maintenance kit number identifies the scheduled service package, while 39218193 identifies the individual motor grease. The applicable parts list should be checked if the grease is being purchased specifically as part of the maintenance kit.
Lubricant compatibility is equally important. Ingersoll Rand cautions that using incompatible alternative greases can shorten motor life. When changing grease types, the applicable service procedure should be followed rather than mixing products indiscriminately.
For maintenance teams, selecting the correct grease and applying the correct quantity can contribute to longer bearing service life, reduced maintenance risk, and more dependable compressor operation. Mobilith SHC 220's broad temperature capability and industrial-duty formulation make it a suitable lubricant where the compressor motor documentation specifically calls for 39218193.

Technical FAQs
1. What is Ingersoll Rand 39218193?
39218193 is the Ingersoll Rand part reference for Mobilith SHC 220 motor grease used for applicable motor-bearing lubrication.
2. What is 47642703001?
47642703001 is identified as an 8,000-hour air-cooled preventive maintenance kit for older Cobra M132-160 screw compressors.
3. What is the relationship between 47642703001 and 39218193?
47642703001 identifies the preventive-maintenance package, while 39218193 identifies the motor-bearing grease. The two numbers do not by themselves prove that 39218193 is included in every 47642703001 package.
4. Which motor frequency is specifically associated with 39218193?
Ingersoll Rand compressor documentation specifies Mobilith SHC 220, part number 39218193, for applicable 60 Hz motors. The motor nameplate should take precedence when a specific grease is specified.
5. What type of grease is Mobilith SHC 220?
Mobilith SHC 220 is an NLGI 2 synthetic grease using a lithium-complex thickener and an ISO VG 220 synthetic base fluid.
6. What is the operating temperature range of Mobilith SHC 220?
Mobil's published product information gives an operating range of approximately -40°C to 150°C for Mobilith SHC 220, subject to the specific application and operating conditions.
7. Can 39218193 be mixed with another motor grease?
Mixing should not be assumed safe. Ingersoll Rand specifically warns that alternative greases can cause shortened motor life because of grease incompatibility.
8. What should be checked before applying 39218193?
The motor grease nameplate, compressor documentation, motor frequency, bearing type, lubrication interval, and required grease quantity should be checked before service.
9. Are Chevron Black Pearl #2 and Chevron SRI 2 alternatives to 39218193?
Ingersoll Rand documentation identifies Chevron Black Pearl #2 (39204292) as the preferred alternative when there is no grease nameplate and Chevron SRI 2 (39161641) as another specified alternative. Esso Unirex N3 (92844729) is specified for applicable 50 Hz motors. These are application-specific alternatives, not universal substitutes.
10. How much grease should be applied to the motor bearing?
The correct quantity depends on the motor frame, bearing arrangement, and service procedure. Over-greasing can be harmful, so the motor documentation and grease information nameplate should be followed rather than using a generic quantity.
