APPLICATION NOTE Use removable Loctite thread locker to hold the adjustable bearing plugs in position. Two parameters must be met in the design and use of square bearings: 1. The 2:1 ratio for cantilevered loads applies to square bearings in the same way as roundway Simplicity® bearings. Binding will occur if the ratio is not met. Note: If only one bearing is used, the 2:1 applies from plug centers. 2. The maximum load and moment load must be met. To calculate the acceptable cantilever or lever arm, multiply the length (from center of the bearing to the center of the load) times the weight. The result must be less than the moment load for that orientation. Example: Distance of cantilever = 3"
