November 27, 2018	Ask the Expert - Wave Spring Compression and Load Welcome back to Ask the Expert! This time Smalley's Expert Engineers answer questions about wave spring functionality. When a wave spring is compressed, does its diameter increase? What happens to the spring load at work height if the outside diameter is confined? The diameter of a wave spring will grow with compression. This is also referred to as diameter expansion, and all Crest-to-Crest®,... Read More>>
November 6, 2018	DIN Interchange DIN standards are documents that specify requirements for products and outline required characteristics which were developed by the DIN Consumer Committee, which resides in Germany. The DIN Consumer Council establishes standard protections internationally for many different products to ensure safety, environmental soundness, and legal certainty. Smalley has compiled an interchange list for its... Read More>>
October 26, 2018	Color Variations in Metals Smalley retaining rings and wave springs can be manufactured in many different types of alloys. Each of these materials has specific properties which make them appropriate for use. Common alloys used include: Carbon steel Stainless Steel (302, 316, 17-7) A-286 Inconel (X-750, 718, 625, etc.) Elgiloy® MP35N® Beryllium Copper Operating environment must be considered when choosing materials; because...

October 8, 2018	Application Spotlight: Wave Springs for Bearing Preload What is bearing preload? When assembling individual bearing components, the outer race, inner race, balls, and retainer all work together so that there is a controlled amount of internal clearance between the rings and balls. This radial play is necessary for proper operation, however, in most applications, it is also necessary to help reduce or eliminate the internal clearance to maintain... Read More>>
September 25, 2018	Application Spotlight: ID/OD Locks - Retaining Ring Functionality Spirolox Retaining Rings have many advantages. They are simple and safe to install and remove. They are produced with little to no waste, which makes them an economical choice for stainless steel rings. They are also groove interchangeable with stamped rings, but they have No Ears To Interfere® with assemblies. These features permit them to fit into an internal and external groove simultaneously...

August 8, 2018	Application Spotlight: Smalley Retaining Rings as a Replacement for Multiple Bolts Bolts are a common fastener used to connect two or more components in an assembly. Although bolts can be used as an inexpensive method of assembly, Smalley Spirolox® Retaining Rings can be used as an alternative in some instances to simplify assembly and potentially save weight and reduce machining costs. As an added benefit, Spirolox Rings provide a more aesthetically pleasing assembly. In the... Read More>>
July 24, 2018	Top 5 Reasons to Use a Crest-to-Crest Wave Spring 1. Reduced Work Height In applications with tight space constraints, Crest-to-Crest® Wave Springs can take up to 50% space than a traditional coil spring. This space saving is made possible with the sinusoidal waves formed in the flat wire. This results in a more compact spring that takes less material to produce and can reduce the overall weight of the spring and assembly. Figure 1. Crest-to-... Read More>>
July 10, 2018	Product Spotlight: Internal Retaining Rings Internal retaining rings act as a removable shoulder within a bore/housing. These internal rings come in a variety of configurations. For applications that require an internal retaining ring, Smalley offers Spirolox® or internal spiral retaining rings, Hoopster® rings, constant section rings, and WaveRings®. This blog post explores the differences between these internal retaining rings and... Read More>>
