Coats E900 Diagnostic Roller Wheel Balancer

Coats ProBalance™ E900 Diagnostic Wheel Balancer

The Coats ProBalance™ E900 sets a new benchmark for precision and speed in professional wheel balancing. Featuring advanced diagnostics, a robust direct-drive motor, and ProMatch™ technology, the E900 is engineered to eliminate wheel vibration, improve ride comfort, and reduce comebacks. Designed for high-volume tire centers and OEM-level service, this balancer delivers speed, accuracy, and durability like no other.

Direct Drive is the Only Choice

The Coats E900 utilizes a direct drive motor and spindle assembly, factory-balanced for zero vibration and minimal noise. This system eliminates the calibration drift and belt slippage common in traditional balancers—providing 10x faster balancing and consistent accuracy for years of service. It’s also the only balancer in its class backed by a 10-year motor warranty.

Diagnostic Roller + ProMatch™ Technology

The integrated diagnostic roller measures both the wheel and tire to identify shape-related vibration before mounting. Combined with ProMatch™ technology, the E900 matches high and low points of the wheel and tire to minimize road force and ensure a smoother ride.

• Detects radial and lateral runout issues before installation

• Reduces vibration comebacks

• Ensures factory-quality balancing on every job

ProBalance™ Technology

Exclusive to Coats, ProBalance™ Technology eliminates residual unbalance automatically during each cycle. This algorithm ensures perfect balance, reduced rework, and higher customer satisfaction — all without manual adjustment.

Speed Thread

With foot-pedal activation, technicians no longer need to hand-spin the hub nut to mount or demount wheels from the shaft. This feature reduces setup time and strain, especially for heavy wheels, and accelerates the entire balancing process.

Auto-Retracting Wheel Lift

The Coats 525 Auto-Retracting Wheel Lift (optional) makes handling heavy assemblies effortless. It automatically lowers as the hood closes, improving safety and eliminating manual lifting steps for faster and easier operation.

Touchscreen Simplicity

The E900 features a high-resolution touchscreen interface that feels as intuitive as a smartphone. Step-by-step visuals and real-time guides make balancing simple, even for new technicians.

Laser-Guided Operation

Dual-position laser pointers (5 o’clock & 12 o’clock) guide exact weight placement, reducing operator error. Lasers also assist in wheel dimension measurement, minimizing manual input and increasing accuracy.

Stop Lock Index

After each spin, the balancer automatically locks the spindle in the correct position for precise weight placement—saving time and improving consistency.
