Introduction
The Ingersoll Rand 47588562001 / 38034914 Motor Bearing Grease Maintenance Kit combines a scheduled maintenance reference with a dedicated motor-bearing lubricant.
Ingersoll Rand parts listings identify 47588562001 as a 4,000-hour preventive maintenance kit, positioned between the 2,000-hour and 8,000-hour maintenance references in the same service family.
The independently documented 38034914 is identified as Grease Motor Bearing. Ingersoll Rand parts catalogs and recommended-parts lists place this reference among service items for compressor equipment, while product records describe it more specifically as “GREASE, 13.7 OZ. TUBE, MOTOR BRG. POLLYREX EM.”
Motor bearings require a lubricant capable of maintaining an appropriate lubricating film under the motor's operating conditions. Correct lubrication helps manage friction and heat while supporting reliable bearing operation over the intended service interval.
The 38034914 designation is particularly useful because it separates the product from Ingersoll Rand compressor fluids intended for other functions. Compressor coolant or airend lubricant performs a different role from motor-bearing grease and should not be substituted solely because both products carry the Ingersoll Rand name.
The available product description identifies Mobil Polyrex EM as the grease associated with 38034914. This provides a more specific lubricant identity than simply specifying a generic bearing grease.
The documented package is a 13.7 oz tube. Trade records also identify 38034914 as approximately 0.4 L per package, providing a useful packaging reference for procurement and maintenance planning.
Ingersoll Rand documentation also demonstrates that motor grease is a recurring maintenance item. For example, compressor parts manuals list 38034914 among recommended service items alongside air filters, coolant filters, and separator cartridges.
Lubrication quantity should not be inferred from tube size. The amount applied to a motor bearing depends on the particular motor and bearing arrangement. Excessive grease can be as undesirable as insufficient lubrication, so the motor-specific maintenance instructions should control the application quantity.
The distinction between 38034914 and other Ingersoll Rand grease references is also important. 39218193 is separately cataloged as Ingersoll Rand motor grease/high-temperature grease, while 92844729 is separately listed as a 400 g grease cartridge. These references should therefore be selected according to the specific motor and equipment requirements rather than assumed to be universal equivalents.
Before lubrication, the technician should inspect the bearing area, grease fitting or lubrication port, existing grease condition, and surrounding surfaces. Contamination should be prevented from entering the bearing during servicing.
The supplied pair is treated as one product listing as requested. Public documentation independently verifies 47588562001 as a 4,000-hour preventive maintenance-kit reference and 38034914 as motor-bearing grease. The available records do not independently establish that 38034914 is the complete bill of materials of kit 47588562001, so the two part numbers retain their respective technical identities.
