If your application demands transporting super heavy loads safely at a high speed, turn to Spinfinity® Casters with TerraTech® wheels. These casters are best working in indoor and outdoor environments and offer two different mounting plate sizes.
Spinfinity® Maxi-Duty Casters contain a heavy-duty "V-Style" seal for the swivel raceway, thicker legs, larger axles, and massive double stacked precision ball bearings to accommodate the higher speeds. The Spinfinity® SEC top plate and inner raceway are forged steel formed from one piece, providing a superior raceway for shock conditions.
The sealed swivel raceways combined with the sealed precision ball bearings qualify these casters, like all Spinfinity® Series, to be 100% maintenance-free.
The dual wheel options provide much more load capacity for the (2) press-on rubber types. For all wheel offerings, the dual-wheel style adds stability and allows for a lower overall height. Note: All wheels with diameters greater than 18" will have black tread.
