Some adaptations are standard, especially for standard motors (NEMA17 or NEMA23), if the dimensions of your motor are not listed, contact us to check the feasibility of your motor adaptation from our rough parts. Tables with ballscrew for motor The ballscrew is reversible and the axial precision of these tables is <0.07 mm. The maxi stroke is 400 mm, and any intermediate stroke can be produced. For a XY cross table, the tables are mounted on each other directly by the body with option 308922* (smooth holes are made in the body of a table). For less precise positioning applications, these tables are available with trapezoidal screw.

Manual XY positioning stage realized with leadscrew table 309L Manual XY positioning stage Tables 309L are assembled carriage on carriage (long carriage version only) with the option 308922 * making smooth holes in the carriage of a table. The standard strokes for each axis are 100, 200 or 300 mm. The same options as the 309L tables are available (handwheel, knob, indicator, locking, base plate). The choice of the type of guide is also the same (bronze or ball bushings). The axial positioning accuracy of these tables is <0.15 mm (in practice 0.02 to 0.10 mm). Positioning tables with base plate Base plates are only available for standard strokes (100, 200 and 300mm). The lower plate allows the table to be fixed by the 4 holes in the central zone, while without a base plate, the table must be fixed by the end plates.

Small manual positioning table Driving by metric screw M6x1 Guided by 2 rods in steel Precision and compactness of this small manual table It is the smallest manual table in our range (width 54 mm / height 27,5 mm). Screw step is 1 mm per round and axial precision of these tables is <0.05 mm after locking in position (<0,10 mm before locking in position). Locking in position is done on the transmission screw, either at the top of the bearing (position B1) or at the end of the table (position B2). Grip knob, position indicator and maxi stroke The shaft outlet is threaded to screw in the grip knob with or without a position indicator (or the handwheel, but it can’t be used with an indicator). The maxi stroke is 100 mm, and any intermediate stroke can be produced. Compact lifting table, miniature cross table and base plate A version « Z axis » allows to fix the table only by its end plate. It can be fixed directly on the carriage of another table for a YZ mounting.

Manual table with double carriage with reversed step (the 2 carriages move away or get closer) Driving by leadscrew Guided by 2 rods 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

Manual lifting table Driving by leadscrew Guided by 2 rods 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)

Manual positioning table drived by lead screw Guided by 2 rods on bronze bearings or ball bushings Precision manual tables The guidance is ensured by 2 rods on 4 calibrated bronze bearings (reduced play) or 4 ball bushings for guidance without play. The guide length of long body tables (309L/M) 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. Manual crossed tables XY or YZ For the creation of XY crossed table, 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. To combine 2 tables in YZ, it is preferable to use a lifting table for the Z axis, mounted by its end on the body of the horizontal table.

Economical manual positioning table drived by leadscrew. Actuated by grip knob. Guided by 2 rods on bronze bearings. Using of economical manual tables Acting is done by a grip knob supplied with the table. Maxi stroke is 100 mm for size 0, and 200 mm for sizes 1 and 2. Any nonstandard intermediate stroke can be produced. The locking in position is done on the trapezoidal screw, either in position B1 (above the front plate) or in position B2 (at the end of the end plate) depending on the access and the space available. The position is visualized by a mechanical indicator or by ruler on the base plate. The fixing on the frame is done by the 2 end plates (laminated holes) or by the end plate in « Z axis » version for vertical applications. The positioning accuracy of economical manual tables The axial positioning accuracy of these tables is <0.20 mm (in practice 0.05 to 0.15 mm), because the axial play is largely eliminated after locking in position

Table for pneumatic cylinders ISO Ø16 to Ø40 Guided on ball bushings Protected by wipers seals More rigid than a H guide unit These tables maintaining the same quality of guidance and rigidity throughout the stroke. For a offcentered payload in vertical, these tables allow to be more rigid than a guide unit in H. Hydraulic shock absorber on this table A hydraulic shock absorber may be placed in opposition to the pneumatic cylinder to dampen, for example, the descent and/or limit the stroke at the output of the cylinder rod. The retracting stroke can be adjusted by the floating rod coupling. Use in harsh environment For dusty environments, additional nitrile or polyurethane scrapers can be added in front of the ball bushings. An anticorrosion version can be proposed with the rods, the coupling and the screws in stainless steel (the carriage and the plates remain in anodized aluminum). It’s possible to make these tables with plain bearings (bronze or polymer) on request.

For pneumatic cylinders ISO Ø8 and Ø10 Guide on bronze bearings or ball bushings The smallest guide unit in the range It’s the smallest unit, suitable for ISO6432 Ø8 and Ø10 pneumatic cylinders, allowing an ISO cylinder to be kept for small guided cylinder applications. It has a long Ushape to remain compact and have a guide length comparable to an Hshape. For environments requiring an anticorrosion version, the steel parts can be supplied in stainless steel (rods, coupling, screws), the body and the front plate are remaining in anodized aluminum (suffix /AC after the reference). Any special stroke is possible, with a maxi stroke of 200 mm.
