| Construction | High-strength materials for reliable performance in industrial and field environments |
| xBoom SKU | xboom-144690 |
| Specification | Details |
|---|---|
| Primary Platform | Unitree B2-W — the wheeled-leg hybrid variant. Not compatible with the standard, legs-only B2, which has no wheels at all |
| Position Specificity | Each of the 4 wheel positions is a distinct part. Unlike the B2 Foot Pad’s universal fit, this component must match the exact leg being repaired |
| Typical Use Case | Repairing a single damaged wheel-and-calf unit, rather than a routine full-fleet refresh |
Built for One Exact Position
Unitree B2-W Single Wheel Component: The Hardware Behind the Rolling Mode
The Unitree B2-W Single Wheel Component replaces a complete wheel-and-calf unit in one part. A 225mm pneumatic tire pairs with the calf rod it mounts to, delivering 50 N·m of torque per wheel and supporting rolling speeds up to 5.56 m/s. That’s the hardware behind the B2-W’s signature ability to switch between rolling on wheels and walking on legs.
Because the B2-W has four independently positioned wheels, this component is sold for one specific leg — left front, right front, left rear, or right rear. So confirm which wheel is actually damaged before ordering, since the four positions aren’t interchangeable.
225mm Pneumatic Tire
Sized for smooth, stable rolling across mixed indoor and outdoor surfaces.
50 N·m Wheel Torque
Enough drive force to keep the B2-W moving confidently in wheeled mode.
5.56 m/s Rolling Speed
Supports the B2-W’s full rated rolling speed of up to 20km/h.
Position-Specific Fit
Ordered for one exact leg, so it matches the B2-W’s engineering precisely.

The Platform It Rolls On
All four of the B2-W’s wheels share this exact tire and hub design, seen here rolling at speed. When one wheel takes damage, this component lets a team replace just that one position instead of the whole leg or the whole robot.
Built for the B2-W’s Rolling Mode
The Unitree B2-W Single Wheel Component restores one wheel position to full, factory-matched performance.

Genuine OEM-Quality Part
Built to maintain the B2-W’s original performance and reliability.
Built for Teams Keeping a B2-W Fleet Rolling
The Unitree B2-W Single Wheel Component suits operators repairing a single damaged wheel rather than replacing the whole robot.
Industrial Inspection Fleets
Restore a single wheel position without pulling the whole unit from service.
Long-Range Patrol & Logistics Routes
Wheel wear is common on routes that favor rolling mode over walking.
Fleet Maintenance After Wheel Damage
A single-part fix means less diagnosis time and a precise, matched repair.
Mixed-Terrain Field Deployment
Sites that mix rolling and walking put extra wear on wheel components.
Research & Robotics Labs
A genuine spare keeps a test platform’s performance consistent after repairs.
Position-Matched Spares Stocking
Keep the right positions on hand instead of guessing which side to stock.
