Shouldered 8mm REX Hub-Shaft (70mm Length)

The two-in-one 8mm REX hub-shaft does double duty as both a shaft and hub solution in rotating assemblies. Seat it fully in goBILDA® 1120 Series U-Channel to drive anything from wheels, to arms, to gears, to sprockets by combining it with flanged bearings and an included M4 screw. Its shoulders are specially engineered to leverage round bearings’ tight tolerances and seat steel Miter Gears—all to simplify 90° drive assemblies where its 8mm REX shaft facilitates incredible positive drive!
