v bearing opportunity

[blueoscar]

hi all,
I have the opportunity to purchase these bearings (see photo) for 3 bucks a piece in quantities of 100. they are of nice quality with good bearings available in single or double bearings. they are .75" or 2mm in diam. Would this diam be useful for a 18* 16 router fore mostly wood?

Something doesn't right here are you sure 2 mm equals anything close to 3/4 inch? Or is my head all messed up...

0.75in is equal to 19.05mm (which is close to 20mm). That's from memory from designing my virtual cnc in SolidWorks set to metric, and trying to use standard metal forms and parts. Fun stuff.

25.4mm = 1in
3.175mm = 1/8in
4.7625mm = 3/16in
6.35mm = 1/4in
9.525mm = 3/8in
12.7mm = 1/2in
19.05mm = 3/4in

0.75" is pretty much 19mm (19.05mm), close to 20mm

Looks like a missing zero...

[blueoscar]

about the zero it's 20mm

[blueoscar]

how about some feedback guys

Are the bearings sealed? If not, dust in them will be a problem.

[blueoscar]

yes sealed,how about the size too small?

[ger21]

Those are the #1 size. Most people use the #2 size, which can carry almost 3 times more load.

I think Widgitmaster used those on this machine, but they turned out to be too small.
