Premature bearing failure will impact a fleet’s efficiency with serious performance, safety and budgetary implications. Proper wheel bearing adjustment is a key factor for optimal bearing life. To reduce premature bearing failure in heavy duty wheel-end applications, the ideal bearing end-play setting should be between 0.001” and 0.005”.

When it comes to replacing bearings and races, NTN has a couple of recommendations we make to installers to ensure that our products meet their maximum life expectancy. When replacing the bearing and race, NTN encourages installers to: 1) Replace both components as a set 2) Ensure both components come from the same manufacturer Replace…

In general, there are two ways to harden steel to the required level: Through Hardening and Case Hardening. Through Hardening In order to harden steel, the iron mix must contain a certain amount of carbon. Carbon dissolves in molten…
