  • China High Load Capacity Support Unit for Ball Screw

    What does radial and axial load capacity mean? The radial force is the force acting perpendicular to the shaft axis. Radial ball bearings optimally absorb forces acting perpendicular to the shaft axis. The axial force acts in the direction of the axis, meaning along the axis, of a body. Optimally, axial ball bearings absorb large forces that act in the direction of the shaft axis.

  • Ball Bearings vs Roller Bearings: How Are They

    2020-2-27 · While a ball bearing can handle a misalignment of up to 0.004 inches, a cylindrical roller bearing might already have difficulty rotating when misaligned by anything more than 0.001 inches. This means that roller bearings need to be designed at a much higher level of precision, making them more difficult and expensive to manufacture.
