All Springs Are Not Equal
Wave Springs offer the unique advantage of space savings when used to replace coil springs. With their smooth, circular coiled sinusoidal wave form, and rolled round edges of pre-tempered wire, Smalley’s edgewound Wave Springs offer many advantages:

  • Reduced spring height by 50%
  • Same force and deflection as coil springs
  • Fit tight radial and axial spaces
  • Over 4,000 standard sizes in carbon and stainless steel.
  • No Tooling Charges for special designs
  • Exotic alloys for all environments

FAQ: TFC's Smalley Ring & Spring Products

1. What industries are your Smalley products used in?


Our Smalley product customers are worldwide and encompass a broad range of environments and
applications. Whilst our products are specified in almost every industry, we have expertise in the
Petro-Chem, Defence, Off-Road and Automotive industries. You can find our Smalley parts specified
in many other industrial markets and they have even been used to put a spring in the step of running
trainers!


2. Are your catalogue parts manufactured in Inconel and, if so, is it still deemed a standard part?
Our standard materials are carbon steel, 17-7 stainless steel, 302 stainless steel and 316 stainless steel
depending upon the product. However we can supply parts from the standard range catalogue in a wide
variety of exotic alloys and, since our parts are manufactured by edgewinding rather than die-stamping,
there are no tooling costs involved. As we have hundreds of alloy sections readily available from stock,
in the factory, we can readily supply non-standard items within very short lead times. Our technical
sales team are on hand and will find an appropriate solution.


3. How are your Smalley parts manufactured?


Our Smalley products have been developed using an exclusive edgewinding manufacturing process that
requires no special tooling. A precision coiling process is utilised that coils flat wire on edge to produce
the highest quality rings and springs available in the market. Smalley parts can be manufactured to your
exact specification in almost any diameter, any number of turns and in any quantity. The minimal
no-scrap process employed virtually eliminates waste and allows for the economic production of small
prototype quantities and for parts produced in exotic alloys.


4. Why can't you just quote it?


TFC strive to offer the perfect Smalley part first time, every time. In order to make sure the parts fit
your application and dimensions perfectly, we may ask questions in the early stages to ensure we are
going to supply the exact part you need. We like to understand the application and any environmental
constraints in order to provide you with the most cost effective solution.


5. Can we obtain free samples of your Smalley products?


TFC is proud to offer free samples of our standard catalogue parts that include Spirolox® retaining
rings, wave springs and constant section rings for you to test in your application. If a standard part will
not satisfy the application, we have a specific pricing policy that allows for the economic production of
a small quantity of prototypes for proving purposes.
