Rocker Roller Bearings
The roller bearing consists of a base plate, two or more rollers, and a top plate. The rocker and roller end is made by providing a saddle and knuckle plate on top of the rollers whereas the same arrangement except rollers is at the rocker end. The rocker and roller end of bearing permits translation as well as rotation, whereas the rocker end permits only rotation.
A moderate amount of maintenance can keep the bearings intact and can continue to work properly for a long period of time.
Rocker and Roller Standard Bearings
Rocker bearings are of various types and styles which are only limited by the imagination of the engineer or the designer. Some railroad companies still have the standard types and sizes. The standard styles are Expansion Rocker Bearings and Fixed Rocker Bearings.
