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.

China Wave Spring 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:

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^(R) with assemblies. These features permit them to fit into an internal and external groove simultaneously, which creates a tamper-proof, concealed ring assembly.

China Wave Spring 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, China Wave Spring Spirolox(R) 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.

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, China Wave Spring offers Spirolox^(R) or internal spiral retaining rings, Hoopster^(R) rings, constant section rings, and WaveRings^(R). This blog post explores the differences between these internal retaining rings and highlights potential applications for each.

Spirolox(R) Retaining Rings are specified to literally retain components within a bore or shaft. What sets them apart from other retaining rings on the market is that they are designed with “No Ears to Interfere(R),” so there is nothing to get in the way of assemblies. But if there are no “ears” or “lugs,” how are Smalley’s rings installed?

Welcome back to the Ask the Expert Blog, where our engineers answer commonly asked ring and spring design questions. This week, our experts field a question about tools for the installation and removal of retaining rings

In addition to standard Spirolox(R) retaining rings, China Wave Spring can also manufacture them with a unique self-locking provision. These self-locking rings are ideal for applications with high rotational requirements. They can also withstand the effects of vibration, rapid acceleration, and some impact loading. Self-locking rings provide a mechanical interference that increases the rotational capacity of external rings. The mechanical interference is a small tab on the ring that “locks” into a slot on the opposite turn of the ring.

1. Do Spirolox rings fit stamped ring grooves?

Yes, Spirolox rings are designed to fit into grooves for stamped or Truarc style snap rings without the downside of protruding “ears”. China Wave Spring has a published interchange listing to help you identify a China Wave Spring ring replacement, or let us know the Truarc part number you are using and we’ll be happy to identify the appropriate ring for your application.
