Ameriloc Hydraulic Locking Devices

Ameriloc® hydraulic shaft locking devices
provide secure shaft/hub connections

Hydraulic Shaft Locking DeviceThrough an exclusive agreement with TAS Schafer GmbH, Ameridrives Couplings now offers hydraulic shaft locking devices which are custom-manufactured to precise tolerances per customer specifications. Ameriloc locking devices are highly engineered to provide years of trouble-free service with features including:

  • Zero backlash
  • Reduced shaft stress
  • High contact pressure for greater torque
  • Easily installed and removed
  • Elimination of keyways or splines
  • Unlimited shaft positioning

The great advantage of the hydraulic SHS device lies in the significant time savings during installation. This system can be tensioned at a pressure of between 1740 and 2900 PSI (120 and 200 bar). With larger diameters, such as 20.8 in. (530 mm), the SHS can be tensioned within only a few minutes, compared to several hours required for a mechanical locking device. This time reduction increases exponentially with the diameter of the connection.

The hydraulic pump required for assembly can be a stationary unit, e.g. at test stations and assembly areas, but the use of a hydraulic hand pump is also possible. In this way, the system can also be tensioned at difficult-to-reach places such as the turret of a wind turbine. Dismantling of the SHS is also supported by the hydraulic system.

If the seals no longer work after many years of operation, the SHS can be removed like a mechanical locking device by loosening the screw connection to release pressurization.

  • All units are pre-assembled, ready to install
  • Torque range from 25,077 to 4,303,675 ft.lbs. (34 to 5,835 kNm)
