Interference required on taper roller bearing cup housing
As a "rule of thumb" what interference is required on a taper roller bearing cup housing (50.292mm dia bearing cup)
I don't know the tolerances that the bearings are made to as they are not a std bearing in an "off the shelf" catalogue, so I
don't know half of the limits info required!
Its an alloy housing btw

Look for something similar on the SKF website, then use their fit calculator. Been a godsend in some of my recent projects!

Just read that you dont know the tolerances. Makes it a bit more difficult with that calculator bit you can play about with it and see what sort of
numbers you come up with.

0.1mm per race tech article if heat shrinking

You'd be surprised how quickly the sales people at B&Q try and assist you after ignoring you for the past 15 minutes when you try and start a
chainsaw

On a taper roller bearing the bearing is preloaded, which in effect expands the outer track into the housing. normally a 50mm track is fitted with a
light push fit.

phelpsa - cheers, yep skf page is useful, but yep, no good on this one as I don't know bearing tolerance. For my purposes I'd say its
nominal as I don't work to single digit microns!! Gone for 0.05 to 0.08mm interference to nominal 50.292mm hole size, fingers crossed, sounds
about right! Want to err on tight side as its alloy and likely to "beat loose" more than a steel housing. I think I could hold a range of
0.03mm on a lathe so hopefully the machine shop will agree!! Its for some alloy hubs, using manta front (or nova rear) bearings, hence the funny
bearing sizes, good old GM!
