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. Among the (2) polyurethane choices, select the standard TerraTech™ (red tread) for general purpose indoor use with the occasional outdoor use. If the application is primarily outdoors or requires continuous-duty (24/7) use at high speeds, the TerraTech™ ULTRA (green tread) will be your best choice. Note: All wheels with diameters greater than 18" will have black tread. Check out our TerraTech Wheel outdoor testing.
