That makes sense, TJ. Steel ball bearings will get replaced when the design engineer designs a product that fits the capabilities of the plastic or other material. Is there a cost savings on the plastic bearings?

Rob, from a capacity standpoint I agree with you.  One cannot replace a steel ball bearing with a dimensionally equal plastic one - the load capacity is much much lower.

But if one works within the bearing's capabilities, one can solve some pretty difficult problems with plastic.

Looks like ball bearings are going the way of many new technologies with a turn toward new materials. From this article, it seems that steel bearings will not be replaced soon.

There are drivers everywhere who turn on their headlights or windshield wipers with no awareness of the development effort behind a switch. Yet from freezing winter to sweltering summer, on dull rainy days and in bright sunshine, switches are expected to function consistently for the lifetime of a car.
Jet engine maker Pratt & Whitney sees additive manufacturing as a production approach that's complementary to -- not a replacement for -- traditional manufacturing processes.
The standards electrical machines and components are required to meet in the food processing industry are far more stringent than those in traditional plant construction. For specialized production environments such as these, components must not only resist thermal and physical stresses, but they must also be resistant to the chemicals used to sterilize equipment.
The word “smart” is becoming the dumbest word around. It has been applied to almost every device and system in our homes. In addition to smartphones and smart meters, we now hear about smart clothing and smart shoes, smart lights, smart homes, smart buildings, and every trendy city today has its smart city project. Just because it has a computer inside and is connected to the Web, does not mean it is smart.
