The sealed bearings on my pellet stove are starting to howl a little. Instead of spending the $275 for a new combustion and exhuast fan I'd like to try and lubricate the sealed bearings on the existing fan. What type of lube should I use? Was thinking either ptfe or silicone, but what would be best for higher temps?

If so, or to answer your question properly, call Eastern Bearing... They were in Lowell, but I think they may have moved to Manchester...lemme look. All they do is bearings...so they will be a good place to ask. 6 Executive Park Drive North Billerica, MA 01862 (978) 262-9888 |

This will take to a page that has a lot of information about grease. You will want a synthetic grease. There is a lot to choose from with temperature ratings shown. |

From doing many many high speed spindles, std grease will start breaking down at 140 deg F., and thats what comes in pre-packed sealed bearings. Get high temp grease. You will need to uncover the bearings, the shields always pop right off. |
