Interest of lifting table
These tables can be fixed by only one end thanks to a reinforced sole, for vertical or offset applications (using the mobile body). This simplifies installation: directly on a plate or directly on the body of another table: no need to build a vertical structure to fix it.
In the fixed body version, they also make it possible to fix a load at the end (on the end flange): the quality of the embedding of the guide rods in this flange guarantees reliability even in the event of a bulky load (example: label printer).
Indeed, the assembly presented on the photo below corresponds to the height and width adjustment application of a label printer on a conveyor. The printer is attached to the end of the horizontal table and the base of the vertical table is attached to the side of the conveyor.
For XY crossed tables, the tables are mounted one on the other directly by the body (long body version only) with the option 308922 * making smooth holes in the body of a table.
Precision and robustness of this range of manual 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.
