Application example

Dental X-ray unit

●Requirements
The linear guide is used for the secondary diaphragm of the dental X-ray unit. The diaphragm is responsible for ensuring that accurate radiographs can be taken. An absolutely vibration-free movement of the unit is important here. The linear guide must run smoothly and evenly.

●Solution
The Franke roller guide FDL12 is integrated directly into the customer-specific slide attachment. The sliding resistance and thus the rigidity of the complete system can be adjusted by means of a lateral set screw. This guarantees a vibration-free procedure.

●Solution used

Linear guides type FDA (customized)

●Advantages
The guide FDZ12 has a smooth, quiet and clean run. The increased preload (0.6 to 0.8 N) ensures that the secondary orifice plate can be moved without vibration. The guide has lifetime lubrication. Sealed single-row ball bearings prevent lubricant from escaping to the outside.

>Principle - Solution

The Franke Principle for Linear Systems

●Uniquely dynamic.
Uniquely individual.

Franke linear systems transfer the ingenious principle of the wire-race bearing to linear movements. Inserted raceways ensure the load capacity on all sides. The rest of the construction can therefore be made of lightweight aluminum. Large guided rollers ensure smooth running - maintenance-free over the entire service life. Thanks to their modular design, Franke linear systems can be individually adapted to requirements.

●Accelerate more easily

Franke linear systems are the first choice when highest dynamics are required. The large rollers are mounted very smoothly. They run with low friction and precisely guided on the inserted tough and hard steel wires. Because almost exclusively light aluminum is used for the entire construction, the moving mass is low. The result: Highest dynamics and energy efficiency.

● Designing homogeneously with aluminum

The main components of Franke linear systems - rails and cassettes - are made of aluminium. Franke linear systems are ideally suited for constructions made of aluminum, because the homogeneous materiality excludes temperature-related distortions.

● The quieter the better

Where Franke linear systems are used, you hear almost nothing from them. Only a quiet, homogeneous noise can be heard. This makes them ideally suited for noise sensitive applications. Furthermore, the whisper-quiet operation is an audible quality feature.

● Highly accurate and durable

Franke's core competence lies in the high-precision manufacture and machining of wire raceways. The pursuit of precision determines every single step of our work. The result is bearing solutions with outstanding accuracy values and an excellent service life.
 

●Patented guidance

Franke track rollers have a groove adapted to the wire tracks. This patented type of guidance prevents the rollers from sliding on their bearing pins and rubbing against the housing. The advantage: a lower friction, more controlled movement.

●Loadable on all sides

The rollers are arranged crosswise and run on one of the four wires each. In this way, forces are absorbed on all sides and the installation position can be freely determined. Depending on the profile rail used, the bearing can be designed with an external guide in an O arrangement (figure right) or with an internal guide in an X arrangement.

● Maintenance-free - carefree
The needle or ball bearings used in the rollers are lubricated for life. This means that no maintenance is required over the long life of a Franke linear guide. For applications in the food industry we also offer lubricant-free roller bearings

●Always the right sliding resistance
The sliding resistance of Franke linear guides can be adjusted to the application at any time using an adjusting screw. Very fine adjustments are possible. This allows the system to be adapted to the load - in the direction of smooth running or in the direction of stiffness and vibration resistance.
