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 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:
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 correct 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, which creates a tamper-proof, concealed ring assembly.
Smalley Wins GM Supplier Quality Excellence Award for 6th Consecutive Year
Posted September 18, 2018
Lake Zurich, IL, August 24, 2018 – Smalley was presented with the 2017 General Motors Supplier Quality Excellence Award, marking the sixth consecutive year Smalley has achieved this prestigious honor. 175 suppliers were presented with this award in 2017, but Smalley was just one of five who has received it six years in a row.
Welcome to another edition of Ask the Expert, a series in which expert Smalley Engineers answer difficult questions about retaining rings and wave springs.
What is the minimum work height of part CM20-L1 if made with carbon steel SAE 1070-1090? What is the load at that height?
This specific part was designed to be compressed to a work height of 2.72 mm to achieve a load of 35 ± 3.5 N.
Smalley stocks over 10,000 standard rings and springs for applications in nearly every industry worldwide. We also understand, however, that the uniqueness of some applications may demand something that isn’t readily available from stock. When that occurs, our team of expert engineers is ready and willing to help you design a part that fits your needs.
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 reduce assembly time, weight, and machining costs. As an added benefit, Spirolox retaining rings provide a more aesthetically pleasing assembly.
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.
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 highlights potential applications for each.
