Introduction
Ingersoll Rand 47555212001 and 39218193 address two complementary aspects of compressor maintenance. The 47555212001 package is associated with an 8,000-hour preventive maintenance program for applicable R90–R110i air-cooled rotary screw compressors with modulation control, while 39218193 is an Ingersoll Rand motor grease used for applicable motor bearing lubrication.
For compressor-driven motor systems, lubrication quality is closely connected with bearing condition and long-term mechanical reliability. Ingersoll Rand documentation identifies Mobilith SHC 220 under 39218193 for applicable 60 Hz motors and emphasizes following the grease specified for the motor rather than making an unverified substitution.
Used within the appropriate maintenance procedure, this combination supports a more complete service strategy: the preventive maintenance package addresses scheduled compressor servicing, while the specified motor grease helps maintenance personnel maintain the lubrication condition of critical rotating components. This makes the pair particularly relevant to industrial plants where compressor availability and motor reliability are important to continuous production.

Technical FAQs
1. What is Ingersoll Rand 47555212001 used for?
47555212001 is an 8,000-hour preventive maintenance kit associated with applicable Ingersoll Rand R90–R110i air-cooled rotary screw compressor configurations with modulation control.
2. What is Ingersoll Rand 39218193?
39218193 is Ingersoll Rand motor grease and is identified as Mobilith SHC 220 for applicable motor lubrication applications.
3. What type of component is lubricated with 39218193?
39218193 is used for motor bearing lubrication in applicable Ingersoll Rand compressor motor applications, with the exact lubrication procedure determined by the motor design and maintenance instructions.
4. Is 39218193 suitable for every Ingersoll Rand compressor motor?
No. Grease selection depends on the motor's bearing arrangement, operating frequency, temperature, lubrication specification, and grease information provided for the specific motor.
5. What grease is associated with 39218193 for 60 Hz motors?
Ingersoll Rand documentation identifies Mobilith SHC 220 under part number 39218193 for 60 Hz motors in applicable compressor equipment.
6. Why is grease compatibility important for motor bearings?
Using incompatible grease can affect lubrication performance and may contribute to premature bearing or motor problems, which is why the specified lubricant should be followed rather than substituted without verification.
7. What can happen if a motor bearing is over-greased?
Excessive grease can increase bearing temperature, create additional resistance, and potentially contribute to bearing or motor failure, so the manufacturer's specified grease quantity and procedure should be followed.
8. Does 47555212001 replace the need for separate motor lubrication procedures?
Not necessarily. The maintenance kit and motor grease serve different maintenance functions, and motor bearing lubrication should be performed according to the specific motor's service requirements.
9. How should the correct amount of 39218193 be determined?
The correct quantity should be determined from the motor frame size, bearing arrangement, lubrication nameplate, and applicable Ingersoll Rand maintenance instructions rather than using a universal grease quantity.
10. What should be verified before using 39218193?
The technician should verify the motor frequency, bearing lubrication specification, grease nameplate, service interval, and recommended grease quantity before performing lubrication.
