Comet 0438.0065 Ball Bearing for MC25 Pump

Comet 0438.0065 Ball Bearing for MC25 & MC20-20 Pumps

A genuine Comet replacement ball bearing for the eccentric shaft of MC25 and MC20-20 diaphragm pumps. It sits in the shaft support and keeps the shaft turning smoothly. A worn bearing can cause noise, vibration, and premature wear on the rest of the pump.

Make sure you have the right bearing. The MC25 uses two different bearings. This is the ball bearing (item 15, 15x32x9 mm) that sits in the shaft support. The 0437.0017 roller bearing (item 8, 15x21x12 mm) is a different part.
