What can I say? These are the same ones that were on my Chinesium band saw and cost less than 1/10th the cost of OEM replacements. I don't understand why anyone would design a blade guide with a radial load bearing to handle axial loads, but Delta has been doing this for over 40 years and has made a fortune off parts. My students make sure they don't last long, but at a dollar a pop I have enough to last me until I retire (hopefully!). They are also working on small Carter rails for deltas.
