Roller bearings - Import export

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

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.

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.

Our rod ends with roller bearings are used for: - changing loads - large swivelling movements with medium to high rotation speed respectively pivoting frequency - rotations with medium to high rotation speed respectively pivoting frequency Please see our catalogue or our website.

Franke bearing asseblies type LVG are bearing assemblies made of aluminum, designed as double row angular contact roller bearings with integrated bearing elements. LVG bearing assemblies are suitable for the highest load ratings. They convince by high rigidity, low rotational resistance and low weight. Designed as roller bearings, they can support high loads from all directions and are insensitive to shocks and vibrations. Franke LVG are sealed on both sides and are set with preload. By using aluminum, Franke beaing assemblies type LVG are 60% lighter than comparable steel bearings.

Franke FTB linear tables impress with their compact and robust design. The integrated aluminum roller guide is maintenance-free and protected from dirt by a metal cover. It is driven by a spindle. Franke FTB linear tables are suitable for precise processes in many measuring, testing and positioning applications. They are available in stroke lengths from 100 to 1500mm.

For optimal functioning of the wipers, the holes in the guide rails should be closed with plastic covers, which are included with every delivery. As a replacement, you can also order them individually.

The stop screws are screwed into the thread (option) of the guide rails. An attached rubber cap dampens the stop. For rail lengths with initial hole dimensions below L11 min. we deliver the drilling pattern offset by half a drilling jump.

In addition to the felt wipers, the metal wipers are inserted into the wiper plate and clipped on. They are used to remove coarse dirt such as metal shavings, welding spatter or wood dust from the track of the rail.

In the case of cassettes for screwing from below, the existing mounting holes are reworked so that screwing from below is possible. Please note any deviating positions of the holes and screw connection sizes.
