In response to growing demand by Aerospace OEM and MRO customers, Pacamor Kubar Bearings (PKB) www.pacamor.com in Troy, NY, has expanded its Class 10,000 Cleanroom Environment. The new ISO 9001:2000 and AS9100:2004 certified manufacturing cleanroom space has been dramatically increased, effectively doubling the size. It has been equipped to provide complete bearing assembly processes including component inspection, bearing assembly, lubrication, specialty inspection processes, secondary operations, test and packaging capabilities.

New equipment for the expanded cleanroom includes a state of the art Running Torque Tester complete with tooling for every bearing size manufactured by PKB; a new heated vacuum impregnation chamber and a new high speed centrifuge for lubrication processes; a new nitrogen gas backfill system for specialized packaging processes; and many other specialty instruments and production tools. Also contained in the new cleanroom, an automated bearing wash system, numerous Class 100 laminar flow benches for ultra clean processing, numerous gages and

precision inspection instruments.

The expanded system is designed to provide tight temperature, humidity, and particulate control. The cleanroom is regularly measured using particle counters to read the return air stream particulate level. PKB's cleanroom regularly maintains cleanliness levels far superior to the Class 10,000 levels to surpass the 1,000 PPM rating on a consistent basis. PKB's ultra-clean Class 100 laminar flow benches regularly report single digit PPM cleanliness levels.

"Customer requests for cleanroom assembled and processed aerospace and medical bearings are on the rise as companies look to eliminate contamination and additional cleaning processes from their final assembly operations," says Ed Osta, Executive Vice President.
