Tsubaki LMEM Series Lift Master (Trapezoidal Screw Thread Type)
Trapezoidal Screw Thread Types are suitable for maintenance applications and other low frequency operations.
RoHS compliant
Features of Trapezoidal Screw Thread Type Lift Masters
Economical
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.
