 | Engineer's Toolbox: 9 considerations for specifying a slewing ring bearing
In applications that require a bearing to support a structure while it rotates (e.g., cranes, radar, tank turrets), premature bearing failure can put people and equipment at risk. While slewing ring bearings have proven themselves countless times in such applications, designers must consider many factors when specifying them. According to engineers at Kaydon, the bearing's support structure, mounting (including bolt strength, tensioning, and hole patterns), installation, and even storage are all factors in a bearing's success or failure.

 | Tech Tip: Controlling DC motor speed in closed loop
According to Portescap, many applications using brush and brushless DC motors driven in open loop can tolerate a natural rotational speed decrease without issue when a load is applied. Demanding applications, however, can require keeping the speed extremely stable using accurate closed loop speed control. Learn the differences between closed and open loop systems and explore using closed loop speed control to regulate DC motors.

 | All about slip rings: How they work and their uses
Rotary Systems has put together a really nice basic primer on slip rings -- electrical swivels that carry a current from a stationary wire into a rotating device. Common uses are for power, proximity switches, strain gauges, video, and Ethernet signal transmission. This introduction also covers how to specify, assembly types, and interface requirements. Rotary Systems also manufactures rotary unions for fluid applications.
