bearings

what is a clearence between shaft and bearing,.001 or less?

[zl1byz]

I think you need to provide a bit more information to get a relevant answer. What type of bearing?

[111angus]

Your right,they are pillow blocks,going on a 30 year old mower.

Hi
All that I have installed have been a slide fit about .001".This will allow for
shaft length changes due to heat.If a bearing is a shrink fit .001" to .0015"
tight they usually have a slide fit on the
bearing O.D. inside the bearing housing.

They slide fit,thats why they have either a locking collar or setscrews,if you want you can put some Loctite under them,just be sure you know where they need to be and get them there before the loctite sets up.Actually you can get away with .002 or even .003" clearence since they are low speed bearings anyway.

Low speed? The drive shaft on my Woods turns at engine speed. That reminds me; I better take a look at mine.

[wierdscience]

3600,like said,low speed

Was wondering why you asked the original question. Are you having trouble fitting some new bearings or something?

Rule of thumb..
For oil lube, use .0005 per inch diameter
For Grease lube, use .001 per inch diameter of shaft

Thanks for the advise will use info to make shaft. Dave
