We look forward toworking with you.No-Tooling-Charges For Customs
PRECISION PRODUCTSFOR CRITICAL APPLICATIONSAll Smalley retaining rings, wave springs and constant section rings aremanufactured with our unique edgewinding process. This eliminates anytooling charges, greatly increases design flexibility and reduces lead times asdies do not have to be produced.Retaining RingsUnlike die-stamped circlips/retaining rings, Spirolox RetainingRings are coiled to the exactdiameter required. They havea uniform cross-section—or, touse our terminology, “No Ears toInterfere” within an assembly—andare free of burrs. Spirolox RetainingRings meet military and aerospacespecifications and are found inthousands of mechanical productsaround the world.Wave SpringsWave springs are precise flat wirecompression springs that fit intoassemblies where space is at apremium. Since the overall lengthsand operating heights of wavesprings are lower than those ofconventional round wire springs,they will often reduce the size ofthe spring cavity by as much as50%. Of course, this will alsoreduce the weight and rawmaterial cost of the assembly.Constant Section RingsConstant section rings, or snaprings, are often specified forheavy duty or impact-loadingapplications. Produced byedgewinding, theyare fixtures in the automotive andheavy equipment industries astheir larger cross section producesstrength and durability. In addition,a variety of Smalley end types areavailable for easy application in awide range of applications.AutomationSpace ExplorationMedicalEnergyConsumer ProductsHeavy MachineryAerospaceAutomotiveSmalley 1 847 719 59005

MEETING YOUR DEMANDSFOR PRECISION COMPONENTSAt Smalley, we have a single, overriding goal: To supply our customers withuncompromising quality and service. It begins with our raw material andextends through every aspect of our world-class manufacturing process.Raw MaterialPrototypesManufacturingFrom one to one thousand pieces, we can produce,test, modify and reproduce your design as often asnecessary—all without special tooling costs.As demand for more raw material sizes continuesto increase, Smalley has invested heavily in our flatwire rolling mill operation. In addition, we offer avertical integration process that has evolved into theproduction of hundreds of material cross-sections ina wide variety of alloys.Edgewinding, also known as “The No-Tooling CostProcess,” is our precision forming operation thatcoils pre-tempered flat wire on edge to create anear-perfect circle, similar to the famous Slinky coiled metal toy. Circular-Grain metallurgy gives ourproducts key benefits including: Strength and stability that is far superior toconventional retaining rings and washers that aresimply stamped through the metal grain The ability to coil to your exact specification in anydiameter and with any number of turns (layers orcoils), effectively eliminating material waste The flexibility to accommodate your designchanges without the need for additional toolingand die modifications A quicker, more economical ability to produce yourlow-volume custom orders and working prototypesEdgewinding ProcessOur engineers work closely with you to ensure youget the ideal prototype for your design: adjustingdimensions, changing the number of waves or turns,and trying different combinations of variables. Finally,we test for function, before production, so we knowit’s right.WarehousingTo meet our “just in time” (JIT) deliveries and anyimmediate requirement you may have, we maintaina substantial parts inventory of every cataloged/standard retaining ring and wave spring in bothcarbon and stainless steel.Conventional StampingProcessSmalley 1 847 719 59007
