How a wheel wears |
|
When Traveling on a horizontal plane, only a small part of the wheels inner race sees any pressure. Since the inner race is stationary and does not turn the same small portion is the only part of the inner race that wears |

Material |
|||||||||
| A through-hardened chrome bearing is essential for long wheel life. The Quantum wheel is manufactured using through hardened, 52100 chrome steel ball bearings, inner and outer races Through hardened is just that, hard all the way through. Case hardened parts are only hard to a certain depth. Once that depth is reached, parts wear out exponentially. |
