Inverted Simplicity Linear Bearing Design Factors

Inverted Simplicity® Linear Bearing Design Factors

Most linear bearings can be used when turned 90° or even inverted, but there are a few factors to consider when mounting linear bearings in this orientation.

In applications where open style bearings are to be mounted at a 90° or inverted completely, plane bearings like the Simplicity® self-lubricating linear bearings have a distinct advantage oInverted Bearingsver traditional linear ball bearings and grooved plastic insert bearings.  Simplicity bearings are a one-piece design with a greater contact area, offering a consistent bearing surface contacting the shaft.  This means that no matter what the orientation is, the bearing surface will always be in contact with the shaft.  In the case of ball bearings, consideration must be given to where the raceways are oriented to ensure that they are located at an angle to handle the load.  The same is true of the linear grooves in a two-piece plastic bearing.

All linear bearings must be de-rated when used in a different orientation, but due to the Simplicity bearings maintaining consistent contact, they are not as susceptible to this design problem.  Use the numbers in the illustration shown to de-rate the Simplicity bearings and account for the stress placed on the outer shell material of the open style bearing.
