Strengths & Limitations: Belt Drive vs. Ball Screw Actuators

The challenge for mechanical automation systems in the past has been the successful conversion of rotational motion from electric or mechanical motors into useful forms of linear motion.  A breakthrough in this regard, the conveyor belt system represented one of ...

Bearing All: Retaining Methods

A bearing by definition is a part of a machine that bears friction, especially between a rotating part and its housing. The architectural definition is a structural part that supports weight. A ball bearing is a rolling element bearing that ...

Rotary Bearing Fits and Tolerancing

Rotary bearings are machine elements that support rotating shafts accurately while providing low friction conditions. In order to maintain a stable bearing performance over a prolonged duration, appropriate bearing fit design considerations are required to avoid any negative effects ([Chart 1]) ...
