Triumph NTB-800 Computer Wheel Balancer, 10"–28" Wheels

How automatic data entry changes the workflow

Every computer balancer needs three inputs before a spin: rim diameter, rim width, and the distance from the wheel to the machine. On the closely related NTB-550, the operator keys in all three by hand. The NTB-800 automates two of them — you enter the rim width, then touch the distance gauge arm to the mounted wheel and the machine captures rim diameter and offset distance on its own. Triumph estimates this trims about 25% from per-wheel setup time. The bigger benefit in a busy bay is error reduction: manual entry is the most common source of operator input error, and a mistyped diameter produces a weight callout that will not solve the vibration. Two fewer keystrokes per wheel removes that failure mode.

What it fits and what it does not

The NTB-800 balances wheels from 10 to 28 inches, with rim widths of 1.5 to 20 inches and tires up to 44 inches in overall diameter, at a maximum wheel weight of 150 pounds. Triumph's fitment guide rates it for passenger cars and 1/2-, 3/4-, and 1-ton trucks, standard 14–24-inch and 16.5-inch automotive wheels, and run-flat and load-range C/D/E tires. A motorcycle mode is built in, though balancing motorcycle wheels also requires an optional motorcycle wheel adapter sold separately. It is not rated for box-truck, over-the-road semi truck, 19.5-inch, 21.5-inch, or implement and agricultural wheels. Shops that see those wheels need a larger-capacity machine such as the Triumph NTB-1200 truck wheel balancer.

Balancing modes, accuracy, and readout

Each spin runs a 6–9 second cycle and resolves imbalance to plus or minus 1 gram. Weight amount and position appear on a dual inner/outer LED display that reads in grams or ounces, so you can work in whichever unit your weight inventory is labeled in. Mode selection from the control panel covers Dynamic, Static, ALU 1–3, ALUS, OPT, split/hidden-weight (HID), and Motorcycle — enough to handle clip weights on a steel wheel, tape weights tucked behind alloy spokes, and hidden-weight placement on wheels where a visible weight is unacceptable. An adjustable least-weight threshold lets you set the point at which small residual imbalances read as zero, so the machine stops chasing amounts that make no difference on the road.

Power, footprint, and setup

The NTB-800 runs on a standard 110V wall outlet and uses a 1/4 horsepower motor, so no dedicated 220V circuit or electrician is required — it plugs into an ordinary receptacle with a North American plug installed. The machine has no built-in surge protection, so Triumph recommends running it through a surge protector, and it should not be hard-wired to the electrical source. Assembled dimensions are 28" x 48" x 62"; it arrives in a 30" x 39" x 51" crate at 300 pounds shipping weight. Set it on a flat, stable floor. Bolting down is not required by default, but if the machine shakes or shifts while spinning a wheel, the manual calls for anchoring it to the ground for accurate results.

Key features

• Automatic data entry — enter rim width only; the gauge arm captures rim diameter and offset distance on contact, cutting setup time about 25% and removing the most common source of input error
• Foot-pedal wheel brake — locks the shaft so the wheel holds position while you apply stick-on or clip weights
• ±1-gram accuracy on a 6–9 second cycle — resolves small imbalances without a long spin
• Eight balancing modes — Dynamic, Static, ALU 1–3, ALUS, OPT, split/hidden-weight (HID), and Motorcycle, selectable from the control panel
• Dual inner/outer LED display — reads weight amount and position in grams or ounces
• Adjustable least-weight threshold — small residual imbalances read as zero instead of calling for weights that do not matter
• 110V operation on a 1/4 HP motor — plugs into a standard wall outlet, no dedicated high-voltage circuit
