Introduction
The Ingersoll Rand 47588561001 / 38034914 Motor Bearing Grease listing combines a scheduled-maintenance reference with a specific motor-bearing lubricant.
Ingersoll Rand parts catalogs identify 47588561001 as a 2000-hour preventive maintenance kit. It belongs to a broader maintenance family that includes 4000-hour and 8000-hour preventive-maintenance kits.
The associated 38034914 component is separately documented as “GREASE, MOTOR BRG. POLLYREX EM” and is identified as an Ingersoll Rand motor-bearing lubricant. Industrial Service Solutions specifically lists it as a Genuine/OEM Ingersoll Rand part.
The lubricant is identified as Mobil Polyrex EM, a product designation that is important when determining compatibility with existing motor-bearing grease. The available Ingersoll Rand compressor documentation emphasizes that the grease specified on the motor nameplate should be followed and warns that incompatible grease can shorten motor life.
The standard package is a 13.7 oz tube, equivalent to approximately 0.405 L. Import records independently describe 38034914 as a 13.7 oz motor-bearing Mobil Polyrex EM grease tube, supporting the published package identification.
Motor-bearing lubrication is a relatively small maintenance task compared with oil changes or separator replacement, but it can have a significant effect on motor reliability. Correct grease selection helps maintain the lubrication film required between bearing surfaces and reduces the risk associated with incorrect lubricant chemistry.
The distinction between 38034914 and general compressor lubricants is particularly important. It should not be substituted with compressor coolant, airend oil, gearbox lubricant, or valve lubricant simply because those products are also sold under the Ingersoll Rand brand.
Other Ingersoll Rand grease references exist for different applications. For example, 39218193 is identified as motor grease/high-temperature grease, while 92844729 is another Ingersoll Rand motor-grease reference supplied in a 400 g cartridge. These should not be assumed to be interchangeable with 38034914 without confirming the motor's lubrication specification.
The correct quantity is equally important. Compressor motor documentation warns against over-packing motor bearings with grease because excessive grease can contribute to motor failure.
For maintenance planning, the compressor model and motor nameplate should be checked before lubrication. Where the motor carries a specific grease designation, that specification should take precedence over selecting a lubricant based solely on brand or apparent application.
The supplied two-part-number combination is treated as one product listing as requested. Public documentation independently verifies 47588561001 as a 2000-hour maintenance-kit reference and 38034914 as motor-bearing grease; the available records do not independently establish that 38034914 constitutes the complete contents of kit 47588561001.
