Stainless Steel Bearings

[Verne Koester]

Anthony,
Double checked the bearing and it's an NTN 6904 LU. Interesting note is that the number is on the seal as opposed to being stamped into bearing. However, I have a post from this List that I saved last year that indicates that it's a 6904LLU/2A. By the description given at that time, it sounds like the same bearing. I don't actually need any at the moment as I have 2 spares. As well as they are performing, that'll easily be two seasons worth. Appreciate you checking it out though. Some of the other guys may need some. Missed seeing ya at Westland.

Verne

  Verne,
  Looks like you were quoted the "man off the street" cash matrix price at $42.00 I don't know who you went to, but it is common practice to charge list price to customers with no buying relationship with the supplier. That price is also very negotiable if you ask. I just looked in our system and don't find an exact listing for that part number. That doesn't mean we don't carry it, it could just be called something else by us, or it is just not loaded in our product file. This is what a search of our system returned:

  Part Description     Vendor                           Mfg                     Recode Master
  6904NR                NTN BEARING CORP      NTN                     *Obsolete*
  6904ZZ                 NTN BEARING CORP      NTN                      6904ZZ/2A
  6905LLU               NTN BEARING CORP      NTN
  6904LLU/2A          NTN BEARING CORP      NTN
  6904LLU2A           NTN BEARING CORP      NTN                     6904LLU/2A
  6904LLUC3/2E        NTN BEARING CORP      NTN

  That is just a small sampling of possible matches, excluding the exact part number that is unlisted. It is possible that we don't list it in our product file because we don't sell a lot of them, but as an authorized NTN distributor we can buy them at a pretty good cost. I checked the "near matches" and they ran about $17.00 on average.

  I have missed competing like crazy!!! Between work ,a hectic school schedule, and the endless rain I have only gotten out to fly three times this year. The summer semester ends at the end of July, and my MBA program starts August 24th so I am going to do my very best to sneak in at least one contest.

  Good luck to everyone preparing for the nats.

    Anthony,
    The NTN number is 6904LU. The bearing supplier closest to me wants 42.00 each. Tower sells it packaged as the O.S. 1.4 EFI replacement part for 26.00 each. Same number, same manufacturer (NTN) - go figure. All I know is they work, easily last a whole season plus and let me concentrate on flying instead of engines - the very reason I went back to 2-strokes in the first place. 

    Gonna see ya at Westland?

      Does anyone know the NTN part number for the OS 140 RX SS bearing set. I work for the second largest bearing distributor in North America and could get them for 2% above cost if I had the part number. Otherwise I have to take mine out and mic it. 

      We also distribute some very cool linear motion items that, if lighter, would be great in a pattern plane. We have a SS shaft, which I suppose could be carbon fiber, that runs through a long cylinder containing ball bearings in a serpentine arrangement. It guarantees precise linear motion with almost no friction whatsoever. If the cylinder were 30 feet long, a small push would send the shaft all the way to the other end. If I were more industrious, or had the time, I would take it home and rework it to make it lighter.

        Which bearing from this source is the correct SS bearing for the OS 
        1.40RX?
