Introduction
The Ingersoll Rand 47550996001 39218193 Motor Bearing Grease combination brings together a major compressor maintenance reference and the associated lubricant used for applicable motor-bearing service. The 47550996001 reference belongs to an 8,000-hour preventive maintenance configuration for the New Cobra 90–160 / M90–160 VSD family, while 39218193 identifies the motor grease reference used in the applicable maintenance configuration.
Motor-bearing lubrication is a small but essential part of compressor reliability. Electric motors operate continuously under mechanical and thermal loads, and their bearings depend on the correct lubricant to reduce friction, control wear, and protect against contamination and corrosion.
The lubricant associated with 39218193 is Mobilith SHC 220. Mobil describes this product as a synthetic, lithium-complex NLGI 2 grease using an ISO VG 220 base fluid. Its formulation is designed for demanding industrial applications and provides adhesion, structural stability, water resistance, and protection against wear, rust, and corrosion.
Temperature capability is another important consideration. Mobil publishes a recommended operating range of approximately -40°C to 150°C for Mobilith SHC 220, making the lubricant suitable for a broad range of industrial operating environments when it is specified for the bearing application.
The 47550996001 maintenance context is particularly useful for planned service. Ingersoll Rand describes rotary maintenance kits as an integral part of factory-recommended maintenance programs, with periodic kits covering 2,000-, 4,000-, 8,000-, and 16,000-hour service requirements.
For maintenance engineers, the important point is that grease selection should follow the motor and compressor documentation rather than relying solely on a generic industrial-grease description. Different motors can specify different grease types, quantities, and relubrication intervals.
Correct application also requires attention to grease compatibility. Mobil notes that admixture with other products can detract from Mobilith SHC Series performance and recommends thoroughly cleaning a system before changing lubricant types.
During major compressor maintenance, using the specified lubricant and applying the correct quantity can help maintain bearing condition and reduce the risk of lubrication-related problems. Over-greasing should also be avoided because excessive lubricant can raise bearing temperature and negatively affect performance.
For purchasing teams, retaining both 47550996001 and 39218193 in the service record provides useful traceability. However, the compressor model, serial number, motor nameplate, and applicable service documentation should remain the final references for lubricant selection.
When correctly matched to the motor, 39218193 provides a professional-grade lubrication solution that supports the bearing reliability objectives of scheduled compressor maintenance.
