Roller-bearing systems

Roller bearings are a common bit-bearing system because they can reliably support large loads and generally perform well in the drilling environment . They are typically used on larger-diameter bits (> 14 in.), which have more physical space to accommodate the rollers. To enhance bearing life, leading manufacturers continually research bearing materials, sizing, and shape.
