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.

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.

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.

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.

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.

Cassette with star grip - standard Cassette with star grip or clamping lever for locking at any position on the guide track. The clamping acts without force on the guide system. It is used for manually movable devices, clamping and holding stops, delivery of tools and processing parts. Please consult us for further information. Cassette with clamp lever Cassettes with clamping levers allow the cassettes to be locked in any position along the guideway. The clamping acts without force on the guide system. It is used for manually movable devices, clamping and holding stops, delivery of tools and processing parts. We would be happy to advise you on application and design.

Franke linear modules type FTD are light, compact and ready-to-install positioning units. They are extremely compact and combine the guide system and toothed belt drive within the housing. Franke FTD linear modules can be used universally. They are suitable for long stroke lengths of up to 7 meters.

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.

Franke FDH linear guides are suitable for linear movement tasks, especially in dynamic pick-&-place applications. They have rollers with angular contact ball bearings for the highest acceleration and speed values, for example when using linear motors as the drive source. Rail elements can be manufactured in lengths from 200 mm to 4000 mm and can be coupled endlessly.

Franke FDG linear guides are suitable for linear motion tasks in almost all industries. They are particularly convincing in cost-sensitive applications in harsh environments and with reduced demands on load capacity. Rail elements can be manufactured in lengths from 200 mm to 4000 mm and can be coupled endlessly.

Franke FDD linear guides are suitable for linear motion tasks in almost all industries. Non-magnetic tracks without influencing the prevailing magnetic fields make them ideal components e.g. in medical technology or in electronics manufacturing. Rail elements can be manufactured in lengths from 200 mm to 4000 mm and can be coupled endlessly

Franke FDE linear guides are equipped with lubricant-free, high-quality needle bearings and are made almost entirely of lightweight aluminum. They are suitable for linear motion tasks in almost all industries, especially for use in food production or in clean rooms. Rail elements can be manufactured in lengths from 200 mm to 4000 mm and can be coupled endlessly.

Franke FDC linear guides are equipped with very quiet, smooth-running, high-quality needle bearings and are made almost entirely of lightweight aluminum. Inlaid raceways made of corrosion-resistant steel make them insensitive to environmental influences as well as moisture or cleaning agents. Rail elements can be manufactured in lengths from 200 mm to 4000 mm and can be coupled endlessly.

Franke FDB linear guides are suitable for linear motion tasks in almost all industries. They are particularly convincing in cost-sensitive applications with reduced demands on load capacity. Rail elements can be manufactured in lengths from 200 mm to 4000 mm and can be coupled endlessly.

Franke FDA linear guides are equipped with very quiet, smooth-running, high-quality needle bearings and are made almost entirely of lightweight aluminum. The sealed roller bearings enable maintenance-free operation over the entire service life. Rail elements can be manufactured in lengths from 200 mm to 4000 mm and can be coupled endlessly

For our bearing assemblies and linear systems, we use high-quality lubricants as standard that are suitable for most applications. Special operating conditions require special lubricants. Standard and special greases are available in the respective container sizes from us as accessories. They can be used when our bearing elements are used for the first time or for relubricating slewing rings.

Elastomer sleeves are available on request for Franke LSA slim bearings. They are used for tolerance compensation and for vibration decoupling. The smooth running can be significantly increased by an elastomer sleeve. Elastomer sleeves for the LSA 6/8 also offer additional sealing of the bearing due to the overlapping of the edges. Elastomer sleeves for Franke slim bearings are available from stock. They can be ordered when you buy a slim bearing and are then included in the delivery. For series production, elastomer sleeves are available by the meter for self-cutting. We recommend gluing the ends with cyanoacrylate glue (e.g. Loctite 406). The use of the elastomer sleeve slightly reduces the stiffness and accuracy of the bearing. The basic static load rating of the bearing also decreases slightly. We would be happy to advise you on the design and construction.

The bearing assemblies are equipped with the S10 boot seal as standard. Temperature: –30 ° C to +80 ° C (NBR). Max. Peripheral speed: 5 m / s. For the sealing of the construction (e.g. when using a bearing element) the seal can be ordered by the meter. The joint is then glued with Loctite 401® adhesive. Special seals are available on request. Franke offers Viton seals for high temperatures or aggressive media.

In the case of larger bearings and bearing elements, adjustment of the rotational resistance is simplified by using washers between the split inner or outer rings. The washers are made of stainless steel. For the coordination it is advisable to provide a theoretical starting gap of 0.5 mm in the design.

Standard Ball Cages Type LBK The belt cage is segmented in the required length and supplied ready for installation with balls. The number of segments depends on the bearing diameter and the ball size. The band cage can also be purchased in one piece for special applications. Special Cages Special cages in the form of ribbon or comb cages are available for special requirements with regard to environmental influences or the installation space. Special solutions such as complete corrosion protection or radiation resistance are also possible. Franke also offers cages made from materials such as plastic, stainless steel, brass and Teflon.

Bearing assemblies with direct drive are suitable for applications where high performance and low space requirements are important criteria. The integration of the drive into the bearing housing means that wear-prone assemblies for transmitting drive power, such as toothed belts, shafts or chains, can be dispensed with. This reduces the required drive energy and also benefits more accurate positioning.

Franke rotary tables of type LTB are centerless, ready to install positioning units. The housing is made of light aluminium. Franke LTB are highly loadable and have an excellent angular accuracy and resolution. They can be used in a wide range of applications and are particularly suitable for movement and positioning tasks in the field of measuring, testing and orientation.
