Polymer Eliminates Contamination in Linear Motion Systems
In an ideal world, linear motion systems would run only in squeaky clean operating environments. In the real world, linear motion systems usually have to run in plants with varying degrees of contamination, chemical exposures or moisture. These less-than-ideal conditions can shorten the lifespan of linear motion systems that rely solely on metal drive components—particularly rack-and-pinions.

To meet the challenges posed by real-world operating conditions, we have designed and delivered many rack-and-pinion systems based on our Power-Core™ polymer. Typically these consist of an Intech Power-Core™ gear with a stainless steel core and a stainless steel rack, though some applications have been best served by a Power-Core™ rack and a stainless steel pinion.
Either way, we’ve found that use of polymers has five key advantages in rack-and-pinion applications:
Rack-and-pinions based on plastics components do have to overcome the perception that they won’t be as durable or carry the same loads as the all-metal designs familiar to motion control engineers. However, we’ve proven that perception false time and time again.
Our experience with gear design and predictive analysis has allowed us to design polymer rack-and-pinion systems that can and do outlast all-metal designs in highly-loaded applications. To learn more, give us a call.
