Need to reach through a linkage to get to a bearing? Does your frame have a shape that blocks the press handle? This bearing guide extender will allow you to place the handle farther away while pressing in and pressing out bearings. This is for use with handle press sets that have 8mm threaded rods. It is 64mm (2-1/2 inches) long and the OD is 13.5mm (0.53 inches).
