The Effect of Sustained Wheel Impacts on Tapered Roller

Oct 02, 2008· Mechanical damage to tapered roller bearings resulting from wheel impacts is a growing concern in the railroad industry. Repeated impacts can cause plastic deformation, wear, and eventually fatigue in roller bearing cages. A servo-hydraulic system was implemented in order to impact a bearing assely with 65 g acceleration impacts at 6 Hz.

Tapered Roller Bearings: inform yourself & order online on

Tapered roller bearings comprise an outer and inner ring with tapered raceways as well as tapered rollers in a window cage. These are single row individual bearings, usually of open design, which for technical reasons are always adjusted against a second tapered roller bearing in a mirror image arrangement. Open bearings are not self-retaining.
