Introduction
The Ingersoll Rand 47545141001 39218193 Motor Grease is a maintenance-oriented combination for compatible New Cobra M90–160 water-cooled rotary screw compressors. The 47545141001 reference represents the 16,000-hour preventive maintenance package, while 39218193 is the motor-grease reference used for applicable electric-motor bearing maintenance.
Electric-motor bearing lubrication is a small but important part of compressor reliability. Bearings operate under continuous rotational loads and depend on the correct lubricant quantity and formulation to control friction, wear, and operating temperature. In a compressor installation that may operate for extended periods, maintaining the motor bearings correctly can contribute significantly to long-term equipment availability.
Ingersoll Rand identifies 39218193 as motor grease, while its compressor documentation specifies Mobilith SHC 220 for applicable 60 Hz motors. This makes 39218193 more than a generic high-temperature grease reference; it is an application-specific maintenance material tied to particular motor configurations.
The relationship between 39218193 and 47545141001 is useful for scheduled maintenance planning. The New Cobra M90–160 maintenance listing associates 39218193 with the major maintenance program, allowing motor lubrication to be handled alongside filtration, oil separation, pressure control, temperature control, and water-cooling service.
Correct grease selection is especially important because electric motors can use different bearing lubricants depending on motor frequency and design. The referenced Ingersoll Rand documentation specifies Mobilith SHC 220 for 60 Hz motors, while identifying other grease references for certain 50 Hz applications. It also instructs users to follow the grease information on the motor nameplate.
Lubrication quantity is equally important. Adding too little grease can leave the bearing inadequately lubricated, while excessive grease can generate additional heat and churning. Ingersoll Rand specifically warns that over-greasing can contribute to bearing and motor failure.
For this reason, 39218193 should be treated as a controlled maintenance material rather than a generic substitute for any available motor grease. Maintenance personnel should verify the motor's grease specification and follow the applicable lubrication procedure, including the correct quantity and service interval.
The 47545141001 package is water-cooled, but 39218193 serves the electric-motor bearing system rather than the compressor's water-cooling circuit. Its inclusion in the maintenance package reflects the broader objective of servicing major reliability-critical systems during the same planned maintenance event.
The grease should also be protected from contamination during storage and application. Dirt, moisture, or foreign material introduced into the bearing lubrication system can undermine the purpose of the maintenance and accelerate bearing deterioration.
Several other Ingersoll Rand grease references appear in compressor documentation, including 39204292, 39161641, and 92844729. These should not automatically be treated as substitutes for 39218193 because grease compatibility and motor application requirements must be confirmed before changing lubricant type.
Exact package dimensions, supplied quantity, net weight, shelf-life specification, and packaging configuration for the current 39218193 product were not sufficiently verified from authoritative documentation. These values are therefore intentionally not estimated.
For maintenance teams managing New Cobra M90–160 compressors, 39218193 provides a traceable motor-lubrication reference within the 47545141001 16,000-hour service program. When the correct grease, quantity, and motor application are verified, it supports reliable bearing lubrication and complements the broader preventive-maintenance strategy.
