Kaydon Bearings Ulta slim bearings - cost is prohibitive -Alternative supplier??
Hi,
I have a project which I would like to use a Kaydon ultra slim bearing set up (Bore=approx 75mm crossection width =2.5mm bearing size 1.5mm.) The price I was quoted for an ultra slim bearing with specs close to the above is around 500bucks. (to me, thats a !!!!!I) This cost rules out Kaydon for this part by a long way. I would like to find a source for around 20bucks if possible. Its a light duty application. Anybody know of a supplier? all the best, Steve |

It's been a long time since I've purchased any, but you may be able to get under $100 for something in that size range.

Some examples: http://www.alpinebearing.com/kpb-series-radial.asp Alpine bearing seems to have good pricing. There were 250 bucks lower in price on a set of tailstock bearings (530.00) for the Leblond lathe. These were NN30xx series super precision bearings. and three angular contact bearings 7305B series.

Anybody know of a supplier? all the best, Steve This sounds like you may need to look at something like furniture- grade "lazy-susan" type bearings, or maybe try finding something that has been rendered surplus on eBay or some other place. As other posters (and you) have noted, it's a huge difference between the Kaydon price and what you want to pay. You could possibly build your own bearing using loose balls and plates with v-grooves with some kind of ball retainer. I have done that before in applications that are manual spin, low-speed, "don't worry about it" sorts of things. If you are looking for any speed and accuracy, though, I doubt that $20 will get you very far, regardless of the load/duty rating. |

Cut a couple of rings off of a solid sleeve type bearing, if it's light duty - ie, oilite or MDS-Nylon. Or re-engineer so that you don't need it so thin and don't cut rings. You're paying for micro-miniature ball bearings (many small parts and fussy grinding) in the original price - you can't afford those at the price you want to pay. eg - MSC has 3" ID 3-3/16 OD iglide plastic bearings for $15.05, which are 2" long - either cut off a ring of that, or change the design. Only thing I find that comes close to your size and price, FYI. If you need a stiffer bearing, they have bronze 3 ID x3-1/2 OD, by 4" long for $50, which you could cut a bunch of rings off of. 3" is 76.2mm ID since you seem to be thinking metrically. -- Cats, coffee, chocolate...vices to live by |
