The new designed rotary swivel unit RT2A is the ideal solution for retrofitting your machine with a 4th and 5th axis. It is based on the proven and robust rotary tables of the RT2A series. The design is kept very compact to ensure the best possible use of space with high load capacity. The rotary tables are equipped with an integrated precision roller bearing, which ensures high torque capacity, radial and axial run-out accuracy. The rotary swivel unit RT2A is available in the size variants RT2A150/200 and RT2A100/150. Various stepper or servo motors can be used as drives. In addition, various types of end or reference point switches are available. The swivel range of the swivel axis can be individually defined, the rotary axis can be rotated without limit. Thus the RT2A rotary swivel unit combines all the advantages of a field-proven standard product with the flexibility of a special version.

A lever clamping permits a simple, fast and exact adjusting of different working levels, without any efforts to adapt the devices. The swivel unit is available for the rotary tables RT2A075, RT2A100, RT2A150 und RT2A200. Field of applications: Assembly technologies, measuring and testing equipments, laser writing, welding, cutting, as well as special mechanical engineering. Features (RT2A100, RT2A200): Individually adjustable swiveling range from -5° to +95°. Fixed stop iin the 0° and 90°. Other positions possible by customer request. Clamp and locking effect through laterally installed, adjustable clamping lever. On one side appropriate scaling in 1° steps. Fixing of the swivel unit through four countersinking holes in the base plate.

Rotary tables with direct drive series RT3 The rotary tables with direct drive are available in different types: RT3A100x100, RT3A100x155, RT3A080x130, RT3A150x100, RT3A150x130, RT3A250x170, RT3A200x060 und RT3G630x225 Rotary tables RT3G630 – high dynamics, high precision, high loading capacity This direct driven rotary table RT3G630 has particularly been developed for machine tool industry and assembly machines. It is characterised by its high precision, highdynamics and its high loading capacity. The rotary table is driven by a permanently excited 3-phase synchronous motor. The rotary plate and the housing are made of gray cast iron.

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. Compact design Integrated motor controller and encoder RS485 or CANopen Interface Operating modes: positioning, speed, flag-position, clockdirection, analog, analog position, torque Position monitoring with automatic error correction up to 0,9° Step resolution max. 1/64 Integrated temperature monitoring Step frequency 0-50 kHz at clock-direction-mode and 0-25 kHz at the other modes

This multisided applicable precision rotary table is available in installation size of 300 mm of rotary plate diameter. The rotation plate is stored by a tempered roller-bearing. This enabled high moment rigidity within the radial and axial range as well as free positioning at less friction moments. The drive takes place alternatively via stepper- or AC servomotors by a hardened and polished precision worm with a worm wheel of bronze. The rotary table is horizontal and vertically applicable by standard drilling plan and bolting face.

Franke bearing elements of type LEL are suitable for high demands on running characteristics and accuracy. Due to the hardened and CNC-ground raceway as well as the ideal geometrical adaptation of ball and raceway radius, they have outstanding bearing characteristics. Bearing elements of type LEL allow the greatest possible freedom of bearing design. The mounting space is between 5.9 mm and 20.9 mm. For special requirements, raceway thicknesses up to 20 mm and ball sizes up to 50 mm are possible.

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, 2 channel.

Based on our many years of experience in developing and manufacturing high-quality machine components, GMN has specialized in the area of high-precision ball bearings as well as the production of high-performance and long-lived deep groove and spindle ball bearings to meet – or even exceed – the highest precision classes P4 and ABEC 7. Certification under international standards ensures the highest precision in the development and manufacturing of GMN ball bearings and guarantees constant, outstanding qualities related to speed suitability, stability and longevity. The broad product range includes a large selection of standard solutions as well as requirements-tailored special designs.

The use of high-precision radial groove ball bearings is especially recommended when axial forces are supported in two directions, but the installation space makes the use of a spindle bearing pair impossible; plus when the best-possible guide for rotating components is needed, but the RPM requirements are less important. Depending upon the load capability and the installation space available, GMN provides deep groove ball bearings in sizes 60 and 62 as per DIN 625. A large selection of various cages, lubricants and covers make it possible to adapt GMN deep groove ball bearings to any application.

For many applications such as machine tools, medical devices, vacuum and measuring equipment, as well as complex bearing systems, GMN develops and offers special ball bearings which meet our customers’ specified requirements.

Magnetic ball bearings are increasingly important in CO2 laser systems and fluid pumps as well as applications in the optics industry. GMN has led the development and manufacture of safety bearings, so-called ‘touchdown bearings’ since the middle of the 1990s."

In addition to our special bearings, GMN develops and manufactures ready-to-install, complex bearing systems. By assigning your entire bearing project to GMN you can fully focus on your core competencies.
