DYNA-SWIVEL™ Cable Swivels for Mechanical, Electro-Mechanical and Electro-Optical Cables

Underwater cables often experience a sudden and uncontrolled release of rotational energy. When a tensioned cable is unable to rotate and suddenly goes slack, stored torque can throw the cable into loops and hockles. Upon cable retensioning, kinks, damage, and failure can occur.

DYNA-SWIVEL fast-acting swivels respond to low cable torque and allow unrestrained rotation. The cable is able to release stored torque to prevent catastrophic cable failure.

Features:

  • Mechanical, Electro-Mechanical & Electro-Optical models available
  • High working load and low break-away or starting torque (Starting torque as low as 10 in-oz on smaller models)
  • Stacked angular contact ball bearings for rotational friction
  • Oil filled diaphragm for automatic pressure temperature compensation
  • Spring-loaded rotary shaft seal prevents intrusion and oil loss
  • Corrosion-resistant shaft seal carrier and prevents deterioration in service
  • O-ring seals on all threaded parts allow for easy repairs
  • Factory sealed construction and vacuum assures reliable performance
  • Choice of mechanical end-fittings and electrical optical connectors
  • Up to 18 electrical channels (1A @ 400V)
  • Optional fiber optic channels
