Stem and Brake
The stem on these casters fits into square tubing and can also be bolted to angle iron.
Tread-on-core wheels have a polypropylene core that is harder than the tread, balancing strength with cushioning.
Rubber wheels are shock absorbing and provide good traction on rough surfaces. 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.
Casters with wheel brake apply pressure to the wheel to stop movement with a press of the foot pedal. Casters with total lock brake the wheel and lock the swivel with one press of the foot pedal.
Sleeve and flanged-sleeve wheel bearings prevent wear to the wheel bore but don't roll as easily as other bearings. Ball bearings are the easiest to roll.
Casters have double-ball swivel bearings for the smoothest swiveling.

Stem Casters with Mounting Holes for Scaffolds
The large stem on these casters fits into scaffold frames and round tubing. All casters have a total lock that brakes the wheel and locks the swivel in one operation.
All wheels have an iron core for strength. Rubber treads are shock absorbing and provide good traction on rough surfaces. Polyurethane treads 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.
Roller wheel bearings provide smooth rolling and are shielded to resist dust and debris. Casters have double-ball swivel bearings for the smoothest swiveling.
