Replace the worn-out lower vertical bearing on your sliding door with this better-than-original solution. The outer roller surface is machined from Delrin® AF blend, a super tough material impregnated with Teflon® fibers for quiet, low-friction operation. The sealed precision ball bearing keeps out dirt and provides a smooth rolling action. Installation Note: You shouldn't need to hammer these bearings on, if the fit over the shaft is snug, take some sandpaper or similar abrasive and clean any corrosion or debris off the shaft before fitting. If any force is needed to seat it, press on the inner race of the bearing, not the outer Delrin® piece. Looking to upgrade all your sliding door bearings? Check out our Sliding Door Roller Bundle.
