An ONDUFIL ® spring washer is a round elastic item of the same family as our undulated, Belleville or Diaphragm spring washers, derived from a new manufacturing technology which consists of simultaneously rolling and corrugating a flat wire corresponding to the ring's width.
Due to smaller and smaller overall dimensions, compression forces (dips) in the field of larger and larger elastic deformations, and more and more varied stiffeners attainable with this complementary technology, an ONDUFIL® spring washer affords a perfect solution.
Our integrated design and engineering department using powerful computational software is capable today of responding rapidly to your needs.
Our totally integrated production workshop is capable today of making ONDUFIL® spring washers from a prototype for large manufacturing series production runs.

Circular washer which are pre-formed with smooth flowing undulations, thus creating a product with spring properties when compressed.
Emmotts is internationally renowned for its range of waved washers used to pre-load bearings in electric motors. Recent development have enabled the company to address diverse applications in situations where relatively high loads are required from limited deflections, for example seals and valves. Split or slotted waved washers can be produced also and materials range from spring and stainless steel to copper and nickel alloys.

Boker's Wave Spring Washers
Boker's is a metal stamping manufacturer of wave spring washers. Wave spring washers, also called wave washers, generally have several curvilinear lobes. The wave spring washer is an efficient washer for obtaining loads when the load is static or the working range is small and the amount of axial space is limited. Wave spring washers often have three, four, or six waves, however, any number of waves can be produced. By increasing the number of waves, the thickness can be reduced for a given load at the expense of decreasing the amount of deflection and increasing the radial stress. Wave uniformity is important because the load rate doesn’t begin until all waves are evenly loaded.
By sending your product specs Boker's can manufacture your wave spring washers in a variety materials.

· Single Turn Wave Springs
Single turn Wave Springs are perfect for tolerance take up and preloading an assembly. Smalley Single Turn Springs are coiled not stamped, providing for an affordable, precision load, stainless steel option. Wave Springs are stocked from ½” to 16” in both carbon and stainless steel.
· Bearing Preload
Single turn wave springs are ideal for bearing preload. The wave spring preloads the bearing through its outer race, taking up play in the bearing. By preloading a bearing, you will reduce bearing damage and wear.
Smalley’s Bearing Wave Spring Series comes in metric sizes to match popular bearing sizes. Over 150 standard bearing springs are available from stock, 16mm to 580mm. Specials are available for unique bearing sizes with No-Tooling-Charges™.

Our more than 36 years’ experience on the market for stainless steel fasteners is brought to bear with particular force in this product segment.
All of the articles with relevance to fastening technology – from the traditional screws and nuts in thousands of individual models, through washers, retaining rings and keys in many versions, right up to bolts, split pins and rivets in just as many variations – can be delivered.
Both the parts standardized in accordance with DIN or ISO and the non-standardized fastening elements (e.g. chipboard screws, mushroom head screws, washers) are available.
Stainless steel remains the material of choice for most of the Lederer customers. Hardly any other material can boast its defining properties, such as corrosion resistance, long lifespan and non-magnetizability. And not least, the optical impression made by a mirror-fi nished stainless steel fastener infl uences the choice of material more often than one would suppose.
