Rotary tables with precision roller bearing and worm drive
The series of RT2A distinguishes by compact design with integrated precision roller bearing and worm drive. The rotary tables are sealed, IP 50 and can be driven in all fitted positions. For the mounting, standard drilling plans and special mounting flange and clamps can be used. Different limit switches are available: Standard: reference impulse, PNP-NC, inductive.
| Field of Applications | Assembly, measuring and testing equipments, laser writing, welding, cutting, as well as special mechanical engineering. The standard light aperture can be used for optical systems or for execution by cable. |
| Drive | Non self locking worm drive i=36:1 (i=25:1 for RT2A075), with easy adjust clearance. |
| Material | Housing: Aluminium anodized black |
| Protection Class | Protection class IP 50 (Other protection classes on request) |
| Ambient temperature | Ambient temperature at the operating location: +10 °C to +40 °C |
| Bearing | Integrated roller bearing with high moment rigidity and concentricity and axial run-out accuracy. Higher concentricity and axial run-out accuracy on request. |
| Lubrication | The rotary tables are lubricated for life, relubrication is not necessary. For interval operation, lubrication runs over a range of at least 60° should be provided. |
| Options | Application on temperature range -40 °C to +80 °C, Application on vacuum to 10-6 mbar, Limitation of rotation and reference point switch (PNP-NC or PNP-NO), pneumatic locking |
Rotary tables RT2A with compact drive
The new compact drives make our established Föhrenbach rotary tables RT2A series to a flexible and cost-saving option for individual applications. Especially in stand-alonemode, so for applications where a higher-level control is not necessary, the rotary table with compact drive shows its strengths. Another possible application area are applications where only a few driving programs are needed.
While the conventional drives are dependent on an external controller unit, for the compact drives no additional controller is needed. The complete electrical parts, including the drive controller and encoder, are integrated on the motor board. Programming is done via standard PC using free software. The operation can be done without a PC, the created driving programs are stored in the compact drive and can be accessed via a separate input
