Linear actuators with trapezoidal spindle
The combination of a high torque stepper motor with a spindle high pitch not only gives the linear actuators of the new series L4118 an extremely high positioning speed (or extremely short manipulating times) but, in its compact form, also enables still high thrust and tractive forces.
Improvements comparuing to the L4218-series:
better mechanical design for the PEEK - nut,
adjustable axial play of the hollowshaft,
30% cheaper with a better avaiability
The relevant SMCI.. microstep drives ensuring resolutions of up to <0.01mm/step are also possible and, hence, this actuator series is also suitable for precision linear axes.
Even higher service lifetimes have been achieved at the same time as well as the improvement in performance due to the relatively high spindle efficiency of >0.5.
Linear actuators are also available with optical encoder for position feedback.
