G'day folks,

posted. In the past I have turned them out of round bar, takes a long time on my lathe. They are quite time consuming as the bore has to be spot on for a nice fit on the bearing.

Just looked up some pipe specs [good ole Machinery's Handbook, as pipe used in Oz is almost exclusively made to US specs], and it looks like Schedule 80 32mm NB pipe would be the go here - 42.2mm OD, 32.5mm bore.

Another possibility would be carbon steel hollow bar - one of the standard sizes is 40mm OD x 25mm ID, another is 40mmx20mm.

Might be worth looking up your WA Bohler Uddeholm branches in Welshpool and Canning Vale for that - I mention them because they do cut-to-length, and it's quite surprising what you can find in their offcuts rack for cheap, over this side anyway.
That's because they deal exclusively in carbon, alloy and stainless steels, so longer offcuts don't just get chucked in a scrap bin, but are racked and marked with the steel grade.

Edit: This is the only likely 35mm ID sleeve I can find in the SKF listings, and I doubt it would be very machinable; probably need to be ground. http://www.skf.com/au/products/seal...dex.html?designation=IR%2035x40x17%20EGS
