If you own a Delta 28-180 or 28-185 bench band saw (or identical band saw from another manufacturer) and are needing part number 1345034 lower guide assembly you will discover like I did that it has been discontinued. The reason I needed the part was that the bearing was making a screeching sound so I really just needed to replace the bearing and I did not need the whole assembly. I was able to order the bearing (623ZZ by VXB) from amazon for $2.51 including shipping. I then used a punch to tap the bearing shaft out of the assembly, replace the bearing, and then tap the bearing shaft back into the assembly. I hope this information helps someone else who needs to repair their saw. (April 22, 2012)
