Installation of Simplicity Bearings with Non-Standard Housings

Not all linear motion applications are the same and the Simplicity® family of self-lubricating linear bearings offer a range of options designed to handle different housings and shaft alignment requirements. Housings

Most standard applications with average shaft misalignment work well with the standard, straight O.D. “FL” bearings inside the standard “P” pillow block that has a spherical I.D. creating ½ degree misalignment capability in all directions.

But in some conditions, a different setup is required or a customer made housing is needed.  In these cases, there are 4 basic options for non-standard housing fits. 

     1. Straight bore housing with press fit bearing for rigid no misalignment capability.  (Not recommended for the vast majority of Simplicity bearing applications.)

     2. Straight bore housing with slip fit bearing for virtually no misalignment capability.

     3. Straight bore housing with slip fit bearing for average misalignment capability.

     4. Straight bore housing with slip fit bearing for severe misalignment conditions.
