There are times when an application calls for a motor to carry a radial load for which sleeve bearings are not suitable. In cases such as low rpm, unusual frames, etc., it may be desirable to convert a customer's existing sleeve bearing motor rather than obtaining a ball/roller replacement motor. This article contains suggested procedures as well as cautions about potential problems with such conversions.  

First, inspect the end brackets to ensure they are mechanically rigid enough to support the load and suppress vibration (see Figure 1). If the end brackets lack rigidity, it may be  necessary to use complete fabricated replacements using thicker material. In other cases, gusseting can be used to stiffen the existing bracket.
