The heavier and more powerful the engine, the stronger the bearings must be to provide this support and protection. In 1839, a special material called Babbitt metal was developed. Babbitt metal was quickly adopted to make strong bearings called Babbitt bearings. Babbitt bearings were used widely in heavy gasoline engine powered equipment.

Most cone crushers have two radial bearings and two axial bearings. The radial bearings are most commonly special cylindrical roller bearing designs, featuring two rollers per pocket with differing roller lengths. The axial bearings typically combine a tapered thrust bearing and cylindrical thrust bearing. Figure 1: Jaw crusher. Figure 2:
