And absolutely indispensable.
Carbon Brush Holder
For electric motors, long service life and maximum freedom from defects is dependent on low-friction, low-wear and burr-free guides for the brushes. An essential prerequisite for this is precisely dimensioned, smooth and perfectly finished securing technology. In the case of carbon brush holders from LANG+MENKE, this is ensured by the freedom from burrs inside the brush guide.
Our specially developed in-house production methods guarantee highest precision and also allow the carbon brush holders to be produced with varying shapes as well as with securing systems that are specifically designed to meet the specified geometries and forces.
Retainers for Cup Bearings
Cup bearing retainers are used in the construction of bearing plates for the technical fixation of spherical bearings and for play-free alignment adjustment. Our cup bearing retainers are suitable for spherical bearings with diameters of 2 to 22 mm and can be fitted into bearing plates made from a wide variety of materials.
We can supply non-self-locking cup bearing retainers, self-locking cup bearing retainers, and self-locking cup bearing retainers with top-mounted springs, also with optional oil recirculation.
Leaf, Flat and Form Springs
Leaf, flat and form springs are used in the field of precision mechanics, in electric motors and in motive power engineering, as well as in the household appliance, automotive and fittings industries.
Wave Washers
One of the most important requirements for today’s electric motors is quiet running. However, totally noise-free operation can only be achieved under ideal installation conditions, which despite the high quality of the ball bearings are not economically viable in series production. Instead, we have addressed this problem and designed a product which has already proved itself millions of times over: the “Original LANG+MENKE Ball Bearing Shim”.
This shim is easily able to compensate for axial tolerances of up to 1.5 mm, thus contributing to both reducing noise levels and extending the service life of the motors and their bearings. The technical maturity of the product can be seen above all in the fact that the shim developed by us has largely shaped the specification profile of DIN standard 42013. As a result, the “Original LANG+MENKE Ball Bearing Shim” can count as a ground-breaking innovation in the design of small electric motors.
Locking Washers
Locking washers are used in all manner of industrial products for safe, fast and screw-free attachment to shafts, rivets and bolts made of steel, brass, plastics and other materials.
LANG+MENKE uses high quality steel strip for manufacturing the locking washers. In order to comply with the diverse applications for the components, we produce designs with differing interior shapes such as round and angular, as well as detachable variations. And we can naturally also supply special designs if required.
Contact and Retaining Components
Contact and retaining components are used in the following areas in particular: precision mechanics, electric motors, power engineering and the household appliance and automotive industries.
We can develop, design and manufacture contact and retaining components to your individual specifications.
Stampings on Spool
To simplify feeding or separating during automated processing, our stamping products are also optionally available in spooled form. We can also supply the necessary parting-off tools on request.
A consistently high quality standard of our stamping process products is assured through opto-electric monitoring, which constantly scans and checks the geometry and shape of the strips.
Bearing Plates and Formed Parts
Bearing plates are used for holding spherical caps or ball bearings in small electric motors. LANG+MENKE bearing plates meet the exacting demands placed on modern electric motors in terms of long service life and quiet operation thanks to their outstanding accuracy of fitting and concentricity.
We develop, design and manufacture formed parts in accordance with your individual specifications. Formed parts are used, for instance, in applications such as gear units, couplings and household appliances. Our product range includes e.g. retaining plates, housings and cover plates with a material thickness up to 2 mm.
Assembly Parts
Time-saving production sequences are imperative for a company’s success. Our in-house assembly service supports you in achieving cost-efficient manufacturing processes. If required, we can supplypre-assembled solutions for assembly parts and structural components, packaged and ready for further processing and completion in your production system.
Single Items or From Strip
The two-component technology of metal and plastic in combination makes design solutions possible that would not be feasible if made from just a single material. It enables the production of components that are very space-saving and lightweight but are nevertheless strong, and so can be used in unusual function combinations.
Whether singly or from strip – everything is possible.
After the injection moulding process, the formed parts can, on customer request, be supplied precisely positioned and ready for the further production process.
