Applications
With a collective knowledge and experience of over 75 years helping engineers innovate, our team strive to collaborate with our customers, to ensure we offer expert solutions for a wide variety of projects and applications.
Linear Applications
Cutting with water jets calls for exact and rapid movements of the cutting head above the work piece, to create even and smooth edges to travel along even more complex geometries.
Solution
Franke Linear Motor module FTH Drive with integrated direct drive.
Advantages
Lightweight aluminium design for low weight and dynamic movement. The linear motor is integrated in the rail profile. This makes the module extremely flat and ensures it requires very little mounting space. The aluminium body and the non-corrosive running bars make the system insensitive to moisture.
Linear Guide used in secondary panel of the dental X-Ray device. Purpose of the panel is to enable exact X-Ray imaging. Primary requirement that the unit travels without any oscillation and the guide must run easily and smoothly.
Solution
FDL12 integrated directly into the customised carriage mount. A lateral grub screw used to set the slide resistance and the stiffness of the system. This guarantees movement without any oscillation.
Advantages
The guide runs evenly, quietly and cleanly. The elevated preload ().6 to ).8N) ensures that the secondary panel travels free from oscillation. The guide comes with lifetime lubrication. The sealed, single-row ball bearing means that no lubricant can leak to the outside.
Due to working at high speeds the linear guides needed must be resistant to aggressive materials (e.g salt, sugar, spray water). The machine had stoke lengths of 1500mm to 2100mm with an average annual mileage of 30,000km per year.
Solution
The aluminium roller guides in series FDA20
Advantages
The aluminium roller guides FDA enables speeds of up to 10m/s. The stroke lengths are infinitely variable. Central lubrication on the cassette achieves high service life and substantial mileage. Grease nipples fitted to the front, allow for convenient lubricant replenishment while the guides are fitted.
Quiet Operation, homogeneous movement and low weight.
Solution
Franke Linear Systems in a variety of lengths with accessories.
Advantages
Lightweight aluminium design for low carrying weight, large-scale rollers for smooth and quiet running and a broad range of accessories to adapt in a variety of shooting situations

Rotary Applications
Roller bearings with high rigidity and highest accuracy are required for use in aircraft protection. The bearings must be able to compensate for thermal expansion.
Solution
Slewing ring LDB80/295 as cylindrical roller bearing made of aluminium with a diameter of 295 mm. A further bearing assembly in the form of a three-point bearing is also used.
.
Solution
Bearing solution used
Bearing assembly type LVB (customized)
Bearing element LEL (customized)
.
Advantages
The LDZ bearing assembly has a radial and axial runout of 0.03 mm. A weight saving is achieved by the light aluminium construction. The load ratings, rigidity and accuracy of the bearing are determined by the raceways. The second bearing has a load angle of 45° (three-point bearing). The outer ring is movable in order to optimally compensate for the thermal expansions that occur.
For the fan of a living room ventilator an absolutely silent bearing must be found. The bearing must compensate for certain manufacturing tolerances of the injection-moulded housing. The housing has a compact design; only a small installation space is available for the bearing used.
Solution
Bearing element LEZ367 with 2.5 mm wire and 6 mm balls.
Bearing solution used
Bearing element LEL (customized)
.
Advantages
To further minimize noise, the ball cage of the bearing is only fitted with every second ball. To facilitate series assembly by the customer, the injection-moulded housing has been optimised. A threaded ring is used to adjust the bearing seat.
The main bearing of the computer tomograph is partly responsible for ensuring that accurate images are delivered. Even at high speeds, it must run quietly and with low vibration. Exact radial and axial runout must be guaranteed..
Solution
A customer specific patented Franke whisper bearing with elastomer. In addition to the high running smoothness, Franke CT bearings have an optimal rotational resistance. The radial and axial runout is a few hundredths of a millimetre, depending on the design and diameter. All Franke CT bearings are adjustable according to customer requirements. The internal elasticity makes the bearing extremely robust even under the toughest operating conditions.
Bearing solution used
Double row angular ball bearing (customized)
Bearing element LEL (customized)
.
Advantages
Extremely quiet running at up to 300 rpm. Noise is dampened by the elastomer (60 dBA). The bearing has a low rotational resistance (< 20 Nm) and electrical insulation between the inner and outer ring. Loads of more than 1,000 kg are possible.
