CCS Type Cut-Out Shifter Couplings

      The CCS Type coupling consists of two flex hubs, one special sleeve without lubrication holes and one accessory kit which includes a special seal for the hub that disengages to eliminate undue friction when the disengaged hub is turning in the sleeve. Standard hub is hand packed with grease.
  • Designed for quick disengagement between the driver and driven equipment
  • Special seal in disengagement hub to prevent undue friction when hub turns in sleeve
  • Widely used on dual drive operations and equipment operating in tandem
  • Available with pins to maintain sleeve in engaged and disengaged positions
  • Shifting mechanisms available upon request
