PUSH-PULL LINEAR FEEDTHROUGH
Huntington’s L-Series Linear Motion Feedthroughs incorporate a unique modular design which allows for actuators to be be easily retrofitted in the field often without breaking vacuum. Body configurations include 1-1/3” and 2-3/4” CF or ISO KF 16 and KF 40 sizes. Optional Long-Life (LL) versions are constructed with million-cycle guaranteed bellows.
