Atlas Copco 2901033803 Grease Tube Motor Bearing Compressor Spare Parts
Atlas Copco 2901033803 is a genuine original motor bearing grease supplied in tube format, designed for periodic relubrication of electric drive motor bearings on Atlas Copco oil-injected rotary screw compressors. This specialized grease is specifically formulated for motor bearing applications, distinct from air end bearing grease requirements.
Product Specifications & Application
The motor bearing grease specification is precisely matched to the operating speed, temperature, and load conditions of compressor drive motors. Electric motor bearings operate under constant radial and axial loads from belt tension or direct coupling forces, generating sustained bearing temperatures above ambient levels.
Key Features
Genuine Atlas Copco original motor bearing grease
Tube format for grease gun application
Formulated for motor bearing operating conditions
Stable performance across full relubrication interval
Prevents bearing noise and premature failure
Service Requirements
Motor bearing relubrication is a timed service task on Atlas Copco compressors with grease-lubricated motor bearings. The relubrication interval, defined in operating hours, is shorter than the main compressor oil service interval. Proper application quantity is critical—both underfilling and overfilling the motor bearing housing can cause operational problems.

Frequently Asked Questions
Q: Our GA compressor motor has two bearing lubrication points — drive end and non-drive end. Does the same 2901033803 grease and the same quantity apply to both, or does each bearing have a separate specification?
On most Atlas Copco GA series motors, the drive-end bearing carries higher radial load than the non-drive end due to its proximity to the coupling or belt drive. While both bearings typically use the same grease specification, the quantity per relubrication event can differ between positions depending on bearing size. Check your compressor's motor service data for specific gram quantities separately for drive-end and non-drive-end lubrication points.
Q: We have several Atlas Copco compressors of different model years on site. Can 2901033803 be used across all of them, or do older motor specifications require a different grease part number?
Motor bearing grease specification can vary across Atlas Copco compressor generations due to changes in motor suppliers and frame specifications across production runs. While 2901033803 is the current genuine Atlas Copco motor bearing grease, it may not be correct for all motor generations in an older fleet. Cross-reference each unit's motor nameplate data and service documentation before application.
Q: The motor on our compressor has not been relubricated since commissioning three years ago. Is a standard relubrication with 2901033803 sufficient, or does the bearing housing need to be cleaned out before fresh grease is applied?
Three years without relubrication significantly exceeds specified intervals for continuously running compressor motors. Aged and oxidized grease doesn't mix cleanly with fresh grease, potentially blocking proper distribution or causing overfilling. For motors exceeding relubrication intervals by this margin, a purge procedure is recommended: apply grease slowly with the motor running to allow old grease displacement through the drain plug.
Contact us with your compressor model and serial number to confirm 2901033803 is the correct motor bearing grease for your specific drive motor specification and to check current availability.
