Ball and roller bearings play a vital role in the performance of countless machine and systems. Ball bearing failure can lead to costly downtime and system failure. Two major causes of bearing failure are improper lubrication and contamination or foreign particles, such as grit, dirt, and dust. Because bearing performance can diminish over time due, proper bearing cleaning and maintenance can greatly improve the operating life and performance of the bearing.

Our Process

Our white room bearing cleaning services and lubrication procedures and facility all correspond with both ISO 7 and MIL‑B‑81793 requirements. This facility is comprised of three separate units.

  • Gray Room. Commonly used for the preparation of bearings prior to cleaning and relubrication procedures.
  • Wash Room. This room houses all proprietary cleaning equipment utilized in the process of cleaning bearings in preparation for relubrication.
  • White Room. Used for the relubrication, testing, and final inspection of the bearings.

Our proprietary industrial degreasing and cleaning equipment can wash or ultrasonically clean bearings and components to completely and safely remove all the grease, grit, and grime using heat, water, solvents, and detergents.
