Placed order for the latest and greatest bearings from Bhogart third week of February, told them my pump was down. I think the most basic of customer service would have been to tell a guy that they didn't *actually* have any of them in yet and they were still waiting on them to come over on a boat from China, but they took my card number and didn't fess up to being still waiting on them until I called about 2 weeks later, said they would have them "soon".
Sent an email Mar 10 asking if my order had shipped yet, no response whatsoever.
Called again last week of March, was told "the tech" dealt with all CMEP stuff but that he had bearings and they would "prioritize" shipping my order out.
I finally got infuriated enough on Monday that when I called and they STILL hadn't shipped yet, I told the person who answered the phone that this service was abysmal and that I was cancelling my order.
Has ANYONE actually received upgrade bearings from Bhogart or are they just vaporware?
Initially I placed an order with Bhogart because their bearing price was better then Ecogreen's, who wanted $81.25/ea for their bearings and didn't lie about how they were waiting on parts to arrive from overseas. Clearly that didn't work out so well. Since my customer didn't have a month and a half to wait around for Bhogart to get off their dead asses and ship what had already been ordered and paid for, we ended up installing some 6908ZZ's from eBay which cost a whopping $12/each shipped.
But I'm still curious for when the next time the bearings fail.
eBay is showing a US seller selling 6908 Zirconium Dioxide bearings with a PTFE cage for $143/ea shipped out of Anaheim. No shields, no grease.
There are Chinese ZrO2 bearings you can get for around $40ish shipped, same deal no shields or grease. At least a couple say that they are fine to use dry in "high vacuum environments" but no word on how long they will last if you actually do so.
I'm halfway tempted to try buying a pair of hybrid bearings with ZZ shields, stripping out the petroleum grease and replacing with something like Dupont Krytox 226. In which case the bearings will be $20ish dollars apiece but a tube of that grease is $26/oz shipped depending on how big a package you buy and which grade. That expensive grease is supposed to last well in vacuum environments though.
Just curious if anyone else has already got a set of the upgrade bearings from either Ecogreen or Bhogart and if so what they are actually like and how they are performing for you.
