Product Overview
The Ingersoll Rand 47555207001 39218193 High Temperature Grease is a lubricant identified in Ingersoll Rand parts listings as 39218193 Motor Grease and described in compressor maintenance documentation as Mobilith SHC 220 for specified 60 Hz motor applications. This identification points to motor-bearing lubrication rather than general lubrication of every compressor component.
In industrial compressor installations, motor bearings operate under rotational load and generate heat during continuous operation. The grease must maintain suitable lubrication characteristics under the motor’s specified operating conditions. Using an unsuitable grease can cause compatibility problems and shorten bearing service life.
For maintenance engineers, the key consideration is the motor’s lubrication specification. The part reference should be matched to the motor application and its grease information plate, where fitted. This product should not automatically be substituted for compressor lubricant oil, gearbox grease or general-purpose grease.

Product Features
- Motor-bearing lubrication: Identified for motor grease applications rather than general compressor oil lubrication.
- Temperature-related application: Intended for lubrication requirements where the specified grease must withstand the motor’s operating conditions.
- Part-number identification: The 39218193 reference helps distinguish this lubricant from other service consumables.
- Grease compatibility considerations: Correct selection helps avoid problems caused by incompatible grease formulations.
- Maintenance planning: Recording the lubricant reference supports consistent servicing and inventory control.
Working Principle
Grease lubricates motor bearings by forming a film between rolling elements and their contact surfaces. This film helps reduce direct metal-to-metal contact, friction and wear during rotation.
The grease must suit the bearing design, rotational speed, operating temperature and the motor manufacturer’s lubrication requirements. If the wrong grease is used, its consistency or thickener system may be incompatible with the existing lubricant. This can impair lubrication and contribute to premature bearing wear.
During motor servicing, technicians should check the motor’s grease specification, lubrication interval and required quantity. The grease information plate, where fitted, takes priority over assumptions based only on the compressor model. Excessive greasing can also cause problems, including increased bearing temperature.
Role in an Industrial Compressor Motor Assembly
The grease supports the motor’s bearing lubrication system. It is separate from the compressor’s main lubricant circuit and should be applied only at the specified motor lubrication points.
Specified Grease → Motor Bearing → Lubricating Film → Reduced Friction at Bearing Contact Surfaces
| System Component | Function | Relationship to the Grease |
|---|---|---|
| 39218193 Motor Grease | Lubricates specified motor bearings | Supplies the required bearing lubricant |
| Motor Bearings | Support the rotating shaft | Depend on suitable lubrication to limit friction and wear |
| Motor Shaft | Transfers rotational power | Rotates through the bearing assembly |
| Bearing Housing | Supports and encloses the bearing | Contains the bearing and its lubrication arrangement |
| Grease Fittings | Provide access to lubrication points where fitted | Allow controlled grease application |
| Motor Grease Information Plate | Identifies the specified lubricant where fitted | Helps technicians select the correct grease |
| Compressor Drive Motor | Supplies mechanical power to the compressor | Contains the motor-bearing assembly |
Industrial Applications
| Application | Typical Equipment | Role of the Grease |
|---|---|---|
| Industrial Compressor Motors | Motor-driven compressor installations | Lubricates specified motor bearings |
| Manufacturing Plants | Motors operating during extended production shifts | Supports scheduled motor-bearing maintenance |
| Industrial Utility Rooms | Compressor drive motors | Maintains the specified lubrication condition |
| Preventive Maintenance Programs | Motor inspection and servicing operations | Supports lubricant identification and service records |
| Rotating Equipment Maintenance | Compatible motor-bearing assemblies | Provides grease where specified by the equipment requirements |
Installation and Maintenance
- Verify the part reference: Confirm that 39218193 matches the lubricant specified for the motor application.
- Identify the motor: Check the motor model and its lubrication requirements before applying grease.
- Check the grease information plate: Use the specified lubricant identification where a motor grease plate is fitted.
- Isolate the equipment: Follow the applicable electrical and mechanical isolation procedure before servicing the motor.
- Review the lubrication interval: Check the prescribed service schedule for the bearing assembly.
- Confirm grease compatibility: Do not mix this grease with the existing lubricant unless compatibility is established.
- Use the specified quantity: Apply the amount required by the motor’s lubrication procedure.
- Clean the lubrication point: Remove dirt around the grease fitting or access point before servicing.
- Use clean application tools: Prevent dust and foreign material from entering the bearing lubrication system.
- Avoid over-greasing: Excess grease can contribute to bearing temperature rise and other operating problems.
- Check operating condition: After servicing, monitor for abnormal noise, vibration or bearing temperature where appropriate.
- Record the maintenance: Document the grease reference, service date and bearing maintenance performed.

Technical FAQs
Why is motor grease different from compressor lubricant oil?
Motor grease is used to lubricate specified bearing assemblies, while compressor lubricant oil serves the compressor’s lubrication and cooling circuit. They have different formulations and applications and should not be substituted for one another without an explicit equipment specification.
Why should the motor’s grease information plate be checked before servicing?
The plate identifies the lubricant specified for that motor. Motor designs and bearing arrangements can differ, so the correct grease should be selected according to the motor’s own lubrication requirements rather than the compressor brand alone.
Can different greases be mixed when topping up a motor bearing?
Do not assume that different greases are compatible. Mixing formulations can change consistency or lubrication performance. Check compatibility and the prescribed changeover procedure before introducing a different grease.
What can cause a motor bearing to overheat after greasing?
Possible causes include over-greasing, incorrect grease selection, incompatible lubricants, bearing wear, misalignment or excessive mechanical load. Adding more grease without checking the cause may worsen the condition.
