Replace the square block guides on your 14" band saw. Delta uses only the one above the table, All other imports uses 2, one above and one below. pics #2, 3,4, +5 show the part (on the right) that rollers replace. Last 2 pics show easy bearing to blade adjustments. Some imports have a style under the table that won't accept the movable guides, but I also provide the improved holder in another listing so you can run rollers above and below, See Final pic, the one on the right is upgrade. eBay item number:145362256829 or variations with hardware choices. Contact me if you need help with anything.
NOTE just foung out that if your saw has a micro adjuster on the left facing the cut side of your blade, the bearing holder may have a slight clearance issue with the thrust bearing. This has been seen on older Deltas
