The polypropylene core makes these wheels lighter and more corrosion resistant than iron-core wheels without sacrificing capacity. Their polyurethane tread combines the abrasion resistance of plastic with the shock-absorbing qualities of rubber. Use them on smooth or rough floors and in areas with debris.

Sleeve bearings prevent wear to the wheel bore but don't roll as easily as other bearings. Roller bearings provide smoother rolling than sleeve bearings.

Firm wheels have higher capacities than soft wheels but absorb less shock.
