Better Wheels – Spinball’s solid wheels feature a urethane tread that is a full 1″ thick for lower shock loads and almost instant speed recovery. Our competitors’ profiled wheel tread is only 3/8″ thick at the center, causing a much higher shock load on the motor shafts, and requiring a self reported 8 seconds recovery time with real baseballs. Pneumatic wheels are almost impossible to keep balanced because they change shape at high speed from centrifugal force. As the speed increases, the unbalanced rubber tire expands, but the balance weights mounted on the steel wheel can’t move, so the wheels become unbalanced. They can also leak air and gloss over from use, reducing grip and therefore accuracy and speed.
Three Sports with One Machine – These machines can be used for baseball, softball and cricket. The only differences between the machines are the interchangeable legs and ball feeder ramps. Single use machines can easily be upgraded to combination machines later by purchasing the appropriate upgrade kit. Motors are mounted on slots to allow for major adjustments between baseball and softball use, as well as for minor corrections for wheel tread wear and ball hardness. Three optional leg heights provide a realistic release point for any player: 32″ for softball, 58″ for baseball and 74″ for baseball-XL or cricket.
Throw Any Pitch from Any Angle – A thrown ball curves in the direction of its spin. The faster the spin, the more it curves. Fastballs have backspin, which causes them to rise, or at least fall slower than they otherwise would. Sinkers and curves have topspin, causing them to drop. Knuckleballs ideally have no spin at all and move randomly. When you set the spin angle and amount on the control panel, and the machine automatically adjusts the wheel speeds to spin the ball in any direction to simulate virtually any pitch.
