  • Why Are Ball Bearings Used in Machines?

    Each ball bearing can hold a load respective to the outer ring band width. Therefore, self-aligning bearings with a double roll capacity can carry a heavier load and remain durable. Bearings come with a static load bearing capacity which is then reflected in the axial hold limitations; some heavy-duty bearing types can carry a load of up to 50% ...
