Understanding Journal Bearings - EDGE

Paper mill rolls often use large specialized spherical roller bearings. Clearly, anti-friction bearings are best for these appliions. However, once the size of a pump (or fan or motor, etc.) gets large enough and fast enough, a gray area is entered. Here you will still find rolling element bearings used successfully but as speeds
