More information on Table with reversed step
Interest of table with reversed step
The two carriages move away or get closer symmetrically during the rotation of the trapezoidal screw thanks to right and lefthand thread, this allows for example to adjust the spacing of the outer guides of a conveyor according to the type of product transported.
Precision and robustness of right and lefthand thread table
The guidance is provided by 2 rods on 4 calibrated bronze bearings (reduced play) or 4 ball bushings for guidance without clearance. The guide length of long body tables (309N/P) allows to accept large loads and torques.
The axial positioning accuracy of these tables is <0.15 mm (in practice 0.02 to 0.10 mm). But the blocking in position is done on the carriage, by pressure on a guide rod, so as to remove the axial play of the nut of the trapezoidal screw after blocking
Handwheel, indicator and maxi stroke of tables with reversed step
The shaft outlet is threaded to directly screw the handwheel or the grip knob with or without position indicator.
Consider the reverse display of the indicators when the table is mounted vertically.
The maxi stroke is 1000 mm (500 mm per carriage), and any intermediate stroke can be produced.
Possibility to adapt to an electric motor (motor not supplied): consult us.
