Cantilevered Loads and Simplicity Linear Bearings
Simplicity® self-lubricating linear bearings work well in cantilevered load situations when specified design guidelines are followed. Use these formulas and examples when using Simplicity bearings with a cantilevered load.
- Maximum Ratio = 2:1
- 1X = bearing separation on same shaft
- 2X = distance from shaft to load or force
Example: If 2X equals 10” then 1X must be at least 5”
CAUTION: Binding will occur if the 2:1 ratio is exceeded.
Note: This principle is NOT load dependent. It is NOT due to edge loading. It is also NOT dependent on the driving force used. The bearings will bind whether hand or mechanically driven. The 2:1 principle for linear plain bearings and the resulting binding is a product of friction.
Working through the following equation will explain why this is a product of friction.
