Wheel Bearings Carry Heavier Loads

 

Timken develops solutions for every aspect of a mining operation, including customized bearings designed specifically for mining equipment like the massive haul trucks. These trucks are in constant motion, pausing only to collect or dump a load of ore.


In addition to the enormous radial loads on the bearings, they also experience axial loads as the trucks turn and corner. And, the bearings must support these loads while being subjected to the constant swirl of abrasive dust and grit.

 

Even standard Timken® tapered roller bearings provide a level of debris resistance that is superior to most of our competitors' debris-resistant products. But for the most severe environments, and in applications where downtime is unacceptable, Timken offers a line of debris-resistant bearings.

 

These bearings start with super-clean, air-melt steel, free from inclusions that could lead to premature bearing failure. Timken steel creates bearings with increased load-carrying capacity, debris resistance and longer bearing life.

 

The bearing components are machined with customized geometries. Then, they undergo proprietary finishing processes to provide enhanced fatigue performance in the thin-lubricant-film environments, such as those found in mining.

 

Finally, special surface coatings and finishes are applied to further deter abrasive damage - bruising, pitting and grooving - that can lead to component wear and reduced bearing life.

 

In wheel bearings for haul trucks, an array of Timken technology comes together to keep the wheels turning.
