Needle Bearing, Pfeiffer, DUO, Part# 330094

This is a replacement needle bearing designed for specific Pfeiffer DUO pumps . It fits the DUO125 and the DUO255M (Index C) models perfectly

Inside your vacuum pump, many parts spin at high speed. The needle bearing sits between these moving parts. Its job is simple but important:

• Reduce friction: It lets parts spin freely without rubbing metal-on-metal.

• Support weight: It holds rotating parts in the correct position.

• Reduce noise: A good bearing keeps the pump running quiet and smooth.

• If you are rebuilding your DUO pump, you may also need seals, gaskets, or other bearings. Check your pump’s manual or contact a service expert to see what else your specific pump model needs.

  Get your Pfeiffer DUO pump back to smooth, quiet operation. Install this needle bearing (Part #330094) and run with confidence.
