Product Overview
The Ingersoll Rand 47627050001 38034914 Motor Bearing Grease is a lubricant identified for motor bearing maintenance in Ingersoll Rand compressed-air equipment. Motor bearings support the rotating shaft and accommodate the mechanical loads generated during operation. Appropriate lubrication helps reduce friction at the rolling contact surfaces and limits wear during continuous rotation.
In compressor installations that run for extended production shifts, the drive motor’s bearing condition affects mechanical noise, vibration and operating temperature. Grease specified for the bearing assembly helps maintain the lubricating film between moving surfaces. The correct application also depends on the bearing design and the motor’s maintenance requirements.
The part number 38034914 is identified as motor bearing grease and is associated with Polyrex EM in product descriptions. The additional reference 47627050001 is retained as supplied for this listing. The intended lubricant should be confirmed against the motor’s requirements before servicing, particularly when replacing grease already present in the bearing assembly.
Motor bearing grease serves a different purpose from compressor coolant or lubricant circulating through an oil-injected airend. These products operate in different parts of the equipment and should not be substituted for one another.

- Application-specific selection: Compatibility must be checked against the installed motor and bearing requirements.
- Controlled application: The amount applied should follow the prescribed bearing maintenance procedure.
- Preventive maintenance: Supports scheduled bearing servicing where relubrication is specified.
Working Principle
Motor bearing grease lubricates the contact surfaces between rolling elements and bearing raceways. As the shaft rotates, the lubricant helps reduce friction and surface wear while maintaining suitable operating conditions inside the bearing assembly.
During service, grease is exposed to mechanical working, temperature changes and possible contamination. Its condition can deteriorate over time, depending on the bearing design and operating environment. Insufficient lubrication may increase friction, while excessive grease can increase churning resistance and heat.
Adding grease is therefore not a universal solution for bearing noise or elevated temperature. Some bearings are sealed and do not require routine field lubrication; others have designated grease points and specific relubrication procedures. The bearing arrangement must be identified before maintenance begins.
When servicing a compressor drive motor, technicians should use the specified lubricant and quantity. Mixing different grease products without confirming compatibility can affect lubrication performance. The bearing housing and lubrication points should also be kept clean to prevent dirt from entering the assembly.
Role in an Industrial Compressor Motor System
The grease supports the motor bearings that carry the rotating shaft. The motor transfers mechanical power to the compressor through its drive arrangement, making bearing lubrication part of the wider equipment maintenance process.

Installation and Maintenance
- Verify the part references: Confirm that 47627050001 and 38034914 match the intended lubricant identification.
- Identify the motor model: Check the installed motor and bearing arrangement before beginning maintenance.
- Confirm relubrication requirements: Establish whether the bearings are intended for periodic grease application or are sealed for life.
- Isolate the equipment: Follow the applicable electrical isolation procedure before accessing the motor or bearing assembly.
- Verify lubricant compatibility: Check that the grease matches the motor specification and is compatible with any existing lubricant.
- Determine the required quantity: Follow the motor or bearing maintenance instructions rather than estimating the amount.
- Inspect lubrication points: Where fittings or grease ports are provided, check for damage, blockage and contamination.
- Keep the work area clean: Prevent dust, moisture and foreign material from entering the grease or bearing housing.
- Apply the specified grease: Use the prescribed method and quantity for the installed bearing arrangement.
- Restore protective components: Refit lubrication plugs, covers and other components removed during servicing.
- Check the operating condition: After returning the equipment to service, observe for abnormal bearing noise, vibration or temperature.
- Record the maintenance: Document the lubricant reference, service date, quantity applied and relevant observations.

Technical FAQs
How should the 38034914 motor bearing grease be selected?
Confirm the motor and bearing requirements, including the specified lubricant and relubrication procedure. Do not assume that a grease suitable for one motor is suitable for every compressor motor.
Can this grease be mixed with the lubricant already inside a bearing?
Do not mix greases unless their compatibility has been established and the maintenance procedure permits it. Incompatible products may affect lubrication performance.
Should grease be added whenever a compressor motor becomes noisy?
No. Abnormal noise may result from bearing wear, misalignment, mechanical looseness or other faults. Inspect the bearing and associated mechanical components before deciding whether relubrication is appropriate.
Why is the amount of grease important during maintenance?
Too little grease may leave bearing surfaces inadequately lubricated, while too much can increase churning resistance and heat. Follow the specified quantity and relubrication procedure for the installed bearing arrangement.
