Looking for 1/2" id flanged bearing .25" thick or less (with flange)
I have been looking for a flanged bearing with a 1/2" ID no more than .25" wide with the flange. I would love to find one with a 1/16" with 3/16 remaining at the nominal OD (usually ~ 1.125")
I have looked at all the usual places. If anyone has a specific place they know carries them, let me know. Thanks alot! |

Re: Looking for 1/2" id flanged bearing .25" thick or less (with flange)
Dynaroll claims to have one. I say claims, because it's an FR-8 bearing but the website doesn't match up with the catalog I have hear in front of me, nor does it match with standard FR-8 bearings at other places. At any rate, it's worth follwing up on.
Dynaroll FR-8 It's an open bearing. The sheilded bearing has a 5/16 overall width. So do the FR-8 bearings at other places like Consolitdated Bearings Best I can do. I used some FR-8s in our tranny last year and got them from consolidated through a local company called Ranger Conveying that deals in gears, bearings, shafting, etc. |

BBSRFX8XXX
That appears to be exactly what you wanted... Although, I must admit, I've never heard of the company... |

We order them from small parts usually. Not always the quickest, but they do carry what you are looking for. Their site is www.smallparts.com . Search for part# BRF-08 . Be sure to include the "F" in the part number because that means the bearing is flanged. Hope this helps.

The Dynaroll one doesn't specify that it is flanged, although the F would make one assume it is.
Also, the other two links have overall widths of 5/16" |

I browsed to the dynaroll one by selecting the flanged R series from their available bearings. here's all their flanged R bearings:

Re: Looking for 1/2" id flanged bearing .25" thick or less (with flange)
The unshielded FR-8 from Consolidated has an overall width of 0.2500.
Also, the Quality BBSRFX-8XXX, unshielded, has a "W" of 0.2500. Get ready to pay, though. The Consolidated bearing costs about $10. I don't know how much the Quality bearing costs. I am also looking for cheaper 3/8" id flange bearings, unshielded. I already use Consolidated, but will try Quality and Dynaroll (and others, possibly). Does anyone know how the prices compare with these companies? Andy B. |

Re: Looking for 1/2" id flanged bearing .25" thick or less (with flange)
Travis (and everyone), be aware that p/n BRF-08 from Small Parts is .250 NOT including the flange and the flange is another .063
However, for future reference to others, SPI p/n BRF-08 and BRF-06 are pretty nice bearings for really good prices if they suit your needs. For Travis, you may want to check out a place called Ace Bearing Supply in Sun Valley, CA. We've had some pretty good luck with them in the past. It is 40 miles away from you which may be a little far but you might want to call and see what they have. |

Re: Looking for 1/2" id flanged bearing .25" thick or less (with flange)
I'll note that I've never actually bought anything from dynaroll. I was looking for bearing specs for a senior design project through www.globalspec.com and ended up getting a catalog in the mail.

Just a thought... Since space is so limited perhaps a bronze bushing? They're usually decent enough for most applications on robots. Also, with a bushing, you could just buy something close for $0.50 and then modify it as needed.

Re: Looking for 1/2" id flanged bearing .25" thick or less (with flange)
I shall reveal my design to no one!
But yes, a bronze bushing wouldn't maintain its eccentricity as much as I would like and roller bearings have less frictional losses. Last year the gears had no bearings or bushings! We simply ran the gear directly on the steel shaft. Scary huh? That is where centerless grinding and different materials come into play. ![]() Last edited by Travis Covington : 08-12-2004 at 21:15. |
