The Lift Master is an electrical lifter allowing overhang and lateral load.

Trapezoidal Screw Thread Types are suitable for maintenance applications and other low frequency operations.

RoHS compliant

Trapezoidal Screw Thread Type

LIFT MASTER -- Features and Structure -- Movie

1. Features of Trapezoidal Screw Thread Type Lift Masters

  • More affordably priced than Ball Screw Types. Ideal for low-speed, low-frequency applications by utilizing the sliding contact of its trapezoidal screw.
Load retaining
  • The trapezoidal screw thread has a self-locking feature based on calculations, making load retention possible.
  • Tsubaki standard products use brake motors.

A brake mechanism is required for motor, since there are situations where the self-locking function may not function due to vibration and shock.
