Crossed roller bearings, Slewing bearings, Customized bearings | RIGBRS - The Meaning of Common Syols on A Bearing Drawing

3/1/2020· The bearing runout syol is the most common syol on a crossed roller bearing drawing or slewing bearing drawing. It is how much one given reference feature or features vary with respect to another datum when the part is rotated 360° around the datum axis. Runout shows the running accuracy of a bearing. Usually, the runout is divided into

How to Extend the Life of Your Slewing Ring Bearings - Power …

A new bearing is asseled with a specific amount of clearance to compensate for slight out-of-flatness in a mounting structure. Wear can increase this clearance dramatically. In machinery with a boom, free play magnified over the length of the boom allows it to rock back and forth under load, reducing the ''stiffness'' in the extended boom.
