Pacamor Kubar Bearings expands cleanroom


To meet growing demand from aerospace and maintenance companies, US-based Pacamor Kubar Bearings (PKB) of Troy, NY, is expanding its Class 10,000 cleanroom. The company is to double the size of its ISO 9001:2000 and AS9100:2004 certified manufacturing cleanroom space in an expansion that will be completed in the fourth quarter 2009. It will be equipped to provide complete bearing assembly processes including component inspection, bearing assembly, lubrication, specialist inspection processes, secondary operations, testing and packaging capabilities.

The expanded cleanroom will be equipped with a 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 nitrogen gas backfill system for specialised packaging processes is also included together with other specialist instruments and production tools. In addition, the new cleanroom will have an automated bearing wash system, Class 100 laminar flow benches for ultra clean processing plus gauges and precision inspection instruments.

The expanded cleanroom will provide tight temperature, humidity, and particulate control and be regularly measured using particle counters to read the return air stream particulate level. The current PKB cleanroom regularly maintains cleanliness levels far superior to the Class 10,000 levels to surpass the 1,000ppm rating on a consistent basis. PKB’s ultra-clean Class 100 laminar flow benches also 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 of PKB. ‘The stringent and comprehensive contamination control methods, along with some of the finest technology in the industry, will meet our customers’ cleanliness requirements and help reduce their time to market.’
