Add-a-Stem Casters with Polypropylene Wheels
Customize the length of your stem by adding any 1/2" dia. Grade 8 bolt through the unthreaded hole in the frame. The lightweight polypropylene wheels are an economical option for smooth surfaces.
Flanged-sleeve wheel bearings prevent wear to the wheel bore but don't roll as easily as other bearings. Roller wheel bearings provide smoother rolling than flanged-sleeve bearings.
Casters have double-ball swivel bearings for the smoothest swiveling.
