N Series


N Series

Rex N-Series is a rod-supported version of the Rex joints. The N-Series in a specialized variation, designed for use where an internal inlet or outlet pipe must rotate with the roll on paper machine dryers with rotary siphons, double shell dryers, rotary steam tube dryer and similar machines. The N-Series Rex Joints accommodate a rotating syphon or distribution pipe as an integral part of the rotating assembly. Nipple and thrust collar keyed together, rotate against carbon graphite seal rings. Thrust collar serves as packing box to prevent leakage along inner pipe; however, rotate as a unit and seal between stationary and rotating part does not rely on any packing. Spring is for initial seating only; in operation joint is pressure sealed. They are available in sizes from ½” to 10”. Standard series joints are suitable for pressure up to 150 PSI. Heavier series joints are suitable for pressures up to 250 PSI.


THE BENEFITS

  • A minimum of rotating parts : With only two continuously moving parts ripple and thrust collar this simplicity of design assures reliability, ease of service.
  • Rod-supported for longer life : Lugs and rods support full weight of joint, take stress and wear it causes off internal components. Some or joint performance.
  • No lubrication required : Seals are self-lubricating when used with media; maintenance is minimized.
  • Self-adjusting for seal wear and pressure changes : Maintains leak-free sealing under changing conditions.
  • Wide range of available constructions : Different materials let you configure the joint for maximum durability under your application conditions.
