FDI Vacuum Compatible Specification
Franke FDI linear guides are equipped with vacuum-compatible needle bearings and are made almost entirely of lightweight aluminum. Special design, material and lubricants prevent outgassing in a vacuum. Rail elements can be manufactured in lengths from 200 mm to 4000 mm.

Mounting position
Any
Lubrication
Lifetime-lubricated with high-vacuum suitable grease, maintenance-free
Clamping with star grip
Cassette with star grip to attach to any position on the rail guide. The clamping does not exert force on the rail system. It is used for appliances that can be operated manually, clamping and holding stops, provision of tools and processing components.
Clamping with clamp lever
Cassette with clamp lever to attach to any position on the rail guide. The clamping does not exert force on the rail system. It is used for appliances that can be operated manually, clamping and holding stops, provision of tools and processing components.
Screw connection from below
Cassettes, modified for screwing from below. In this variant, the existing mounting holes are partially reworked so that a screw connection from below is possible. Please note possible deviating positions and bolting sizes.
Metal Wiper
The metal wipers are placed in the wiper plate along with the felt wipers and clipped on there. They are used to remove coarse dirt such as metal shavings, welding spatter and wood dust.
Bellows
The bellows for aluminium roller guides protect the rail system against coarse dirt. They are available in any lengths. The applied Velcro patches are used for attaching to the cassette and end plate. The cassette wipers are no longer needed. Material: synthetic fabric with one-sided polyurethane coating; temperature: contact heat +80 °C, radiant heat +120 °C.
Stop Screws
The stop screws are screwed into the thread (option) on the guide rails. A fitted rubber cap dampens impact. We deliver the drilling template displaced by one half bore gap for rail lengths with initial drilling dimensions below L11 min. Material: Chlorbutadiene rubber (Cr), black.
Caps
In order to ensure that the wipers function ideally, the bores on the guide rails should be sealed using plastic caps enlosed with the delivery. You can order replacements individually. Material: POM wear-proof plastic, resistant to oil and ageing.

Principle
4 Point ContactFreedom of Design
4 Point contact principle to take load from all directions. The compact and highly resilient four-point geometry of Franke bearings gives you maximum freedom of design.
Compact
Minimal Mounting SpaceMinimal Mounting Space
Needing only a small mounting space, but with a high stiffness, these small but strong bearings make an ideal design component. Light in weight, compact but offering high speeds and high torque loadings.
Material

95% of our products are bespoke versions, designed and built to fit a customers application. Available in sizes from 60 – 2000+ mm, in a wide range of combinations.
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.
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.
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
