The tables manufactured by Meccanica Besnatese range from small to large-size systems, in compliance with standard instructions. Just as for manufacturing on third parties account, the company is ready to accomplish mass-produced work orders in a limited number up to single units.
The components in use are purchased from the most qualified suppliers to offer customers a top-quality finished product for easy replacement.
The tables included in the catalogue are generally used for positioning and handling light objects and if no high level of accuracy and rigidity is required, they can offer an excellent quality/price ratio.

- Linear velocity of the table: max 300 mm/sec.
- Repositioning repeatability: +/- 0.03 mm
- Resolution: according to the controlling and measuring system in use (e.g. pitch 8/400 pulses per revolution = 0.02 mm)
Accessories UPON REQUEST
- Motor support
- Direct assembly: support + joint for motor connection
- Indirect assembly: by means of a drive plate with pulleys and a positive drive belt, velocity ratio 1:1 – 1:2 or others.
- Assembly of tables in the x-y position.
- This type of assembly can be directly accomplished by overlapping the base of a table on the trolley of another one without any intermediate element.
- Limit stop (for mod. Tc120 only)
- 2 inductive proximity switches applied inside the table + flying cable.
