Satellite Antenna
Satellite Antenna
Requirements
A bearing weighing no more than 1kg. Smooth running with simultaneous tilting stiffness must be guaranteed.

Solution
LDB200 made from aluminium, with inner ring geared on the outside.

Advantages
Complete bearing assembly, ready for installation, made of aluminium and with tooth belt gear. Large open centre and low mounting space due to compact structure.

Circular Knitting Machine
Circular Knitting Machine
Requirements
The main bearing in the knitting machine plays a crucial role in the quality of the knitted goods. The highest standards are placed in the precision and operating performance of the bearing, despite the high mechanical and thermal load. The required speeds are up to 60 rpm.

Solution
A ground bearing element from the LEL series with a ball pitch diameter of 400 to 1500mm, made of chromium-silicon, ensures even, smooth running, even in the smallest mounting space. High precision of the bearing in axial and radial runout (<0.03mm) and the outstanding surface quality of the raceways ensure a constantly high quality of the machine.

Azimuth Bearings for Solar Panels
Azimuth Bearings for Solar Panels
Requirements
Bearing assembly to swivel the solar panel. Very slow-moving worm gear to follow the path of the sun. High stiffness to cope with any wind pressure.

Solution
The system uses wire diameters of 7mm and ball diameters of 20mm, to achieve the requisite load rating and stiffness. Other modifications: Special osculation and spherically seated design.

Advantages
Low mounting space thanks to direct integration in the cast housing of the rotary drive. High load rating and stiffness, also attractive series price and other advantages.

Satellite Antenna on Seagoing Vessels
Satellite Antenna on Seagoing Vessels
Requirements
A bearing which required high stiffness across its entire service life (shock stress due to waves and swell). The system needed to possess non-corrosive properties and provide constant rotational resistance across temperature ranges from –25°C to +60°C.

Solution
Bearing assembly LDA166 steel version, with adjusting ring, including coating and LER bearing element.

Advantages
Steel solution delivers constant rotational resistance across the entire temperature range. An additional inlet process with readjustment guarantees high stiffness over the whole service life.

Hubless Rim
Hubless Rim
Requirements
The aluminium-carbon rim on an electric race car should be designed to accommodate the drive and braking systems in its center. The bearings used must require very little mounting space and possess a large open center. Plus they need to securely transfer substantial forces and torques.

Solution
Integrated directly in the housing components of the rim as double row angular contact ball bearings. The Wire Race Bearing handles the prevalent loads and works independent of the material used in the mating components.

Advantages
LEL with wire diameter of 4mm, ball diameter of 3/8’’, 8, 10 or 12 mm. The carrying angle is 45°; in special cases even 53°, due to the mainly axial load. Standard speed are at 30 rpm, and up to 60 rpm for smaller ball pitch diameters The axial load caused by the machine cylinder is around 4000N, depending on the machine type.

Aerial Camera
Aerial Camera
Requirements
Light, customised bearings are required for the articulation of the cardanic suspension; they must possess high stiffness while at the same time remaining smooth and with low breakaway torque and rotational resistance. Forces and torques occur from all directions. The bearings must not impede the camera’s imaging quality.

Solution
LDB155 on high-strength aluminium with customized bore pattern. Anodized-orange by request of the customer.

Advantages
Bearing material, design and coating based on customer specifications. The 4-point contact bearing can accommodate forces from all directions and is insensitive to temperature fluctuation and vibrations. Smooth bearing with concomitant, high stiffness, at a favorable price.

Linear Applications

Water Jet Cutter
Water Jet Cutter
Requirements
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.

Dental X-Ray Device
Dental X-Ray Device
Requirements
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.

Food Packaging
Food Packaging
Requirements
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.

Mattress Production
Mattress Production
Requirements
Bonding points to bond the mattresses are positioned in the centre of the gantry. The guides are used to travel to the gantry along the x and y axes. The assembly surfaces of the guides are not processed in order to save costs.

Solution
The aluminium roller guide FDA25 in a length of 2000mm.

Advantages
The guide unit, motorised by a toothed belt, travels at a speed of 50m/min. The guide is fitted directly to the unprocessed aluminium substructure. This involves mounting aluminium on aluminium, which means there is no bi-metal edict in the event of temperature fluctuations. This cost efficient solution makes the system competitive.

Camera Slider
Camera Slider
Requirements
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
