KTR Corp. offers the RADEX-NC, TOOLFLEX, and the ROTEX GS series couplings for cleanroom applications.
The couplings were subjected to emission measurements to determine their suitability for use in cleanrooms and classification into one of the cleanroom classes. All three series are servo couplings for precision applications since precision drives are used in many cleanroom applications. Since there are less surfaces moving towards each other, less wear arises on zero-backlash couplings than on drive systems with backlash making them suitable for cleanroom applications. All couplings tested reached purity Class 7 or Class 8 according to ISO 14644-1. This corresponds to GMP class C in the pharmaceutical industry.
