FRANKE GMBH - innovative Lagerlösungen

Franke rotary tables type LTA are light, compact, ready to install positioning units for speeds up to 100 rpm. They are highly loadable and have excellent concentricity and axial run-out accuracy. Rotary tables LTA are versatile and are particularly suitable for light machining tasks as well as dynamic handling and assembly applications.

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.

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.

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.

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.

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.

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.

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.

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

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.
