Spinfinity® Maxi-Duty Casters w/ Dual Press-On Wheels
Capacity Range: 2800 – 15,600 lbs.
This Spinfinity® Maxi-Duty Dual Wheel Caster Series is a new kingpinless caster machined from heavy 1045 forgings installed with dual TerraTech™ wheels with press-on tires designed for applications moving extra heavy loads at speeds up to 10 mph. The dual wheels 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. This series matches the same 8-1/2" x 8-1/2" mounting plate as our original Maxi-Duty but that's where the similarity ends.
The heavy duty wheels are mounted in an all-new kingpinless caster rig. The top plate and inner raceway are forged steel formed from one piece, providing a superior raceway for shock conditions. Engineers also added a new heavy duty "V-Style" seal for the swivel raceway. Engineers then enhanced the caster series with thicker legs, larger axles, and massive double stacked precision ball bearings in the wheels to accommodate the higher speeds. The sealed swivel raceway combined with the sealed precision ball bearings qualify this series, like all Spinfinity® Series, to be 100% maintenance-free.
To help with wheel selection, the Black rubber will provide the most cushion and is best suited for outdoors but has much lower capacity compared to the poly offerings. The white rubber grants similar benefits to the black and provides the added benefit of being non-making so it's best suited for indoor use. Among the (3) polyurethane choices, select the standard TerraTech™ (red tread) for general purpose indoor use with the occasional outdoor use. For very rough floors with coarse debris or super-tough terrain such as gravel, the TerraTech™ MAX (yellow tread color) is your best choice because its tread has the highest tear resistance. If the application is primarily outdoors or requires continuous-duty (24/7) use at high speeds, the TerraTech™ ULTRA (natural tread color) will be your best choice.
