About Casters and Wheels
More
Add-a-Stem Casters with Polyurethane Wheels

Customize the length of your stem by adding any 1/2" dia. Grade 8 bolt through the unthreaded hole in the frame. Polyurethane wheels combine the abrasion resistance of plastic with the shock-absorbing qualities of rubber. They can be used on smooth and rough floors and in areas with debris.
Tread-on-core wheels have a polypropylene core that is harder than the tread, balancing strength with cushioning.
Caster without wheel bearing has a wheel that rides directly on the axle, making it an economical choice for equipment not frequently moved. 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.
Double-ball bearings in the swivel provide the smoothest swiveling.
