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 

Spirolox Rings

Spirolox Rings are manufactured by coiling the ring from flat wire and have many advantages over stamped retaining rings/circlips.

Advantages of Spiral Retaining Rings
* No gap – full 360° retaining surface
* No Protruding lugs to interfere with mating components (uniform cross section)
* Economically produced in stainless steel
* Easy installation and removal (see guide below)
* No tooling charges on custom designs
* Available in a wide range of exotic materials and finishes
* Special end configurations to suit your application  

Our supply of spiral rings includes a bespoke service to meet your exact requirements and our expansive range is used in a number of industries including petrochemical, automotive and aerospace.

Laminar Sealing Rings

Smalley Laminar Sealing Rings are a metallic labyrinth seal consisting of multiple rings in a groove.

Numerous configurations available
Produced from metal; not rubber, neoprene, or other non-metallic materials
Able to withstand high temperatures and corrosive environments
Standard sizes:
15mm to 1300mm / 5/8" to 50". Special seals manufactured with No-Tooling-Charges. Smalley’s Laminar Seal Rings are interchangeable with FEY Rings.

Threaded Fasteners

Within our eclectic supply of technical fasteners and standard fasteners range, we offer a wide variety of options in threaded fasteners. Our threaded fasteners are suitable for many applications. They are durable and professionally manufactured.

  • High tensile bolts and screws
  • Thread forming screws
  • Rivets
  • Flat washers
  • Nuts
  • Black and mild steel bolts
  • Toothed washers

Panel Fasteners

We are a leading supplier of a wide variety of technical fasteners to industry and manufacturing.

As part of our standard fasteners product range, we supply panel fasteners (wire and pipe), seals, disc springs, circlips and threaded fasteners. We also supply lubricants and binding substances.

A few examples of our extensive panel fasteners stock range include:

  • Plasti rivets
  • Rokut rivets
  • Micro push rivets
  • Fir tree fix
  • Drive fasteners

Spirolox retaining rings

Smalley 2-turn spirolox retaining rings are specifically designed to take high axial loads yet can still be installed and removed easily. Depending on the installation method and installation stress, these rings can often be reused without any issues. If your application requires frequent installation and removal, it would be best to keep the installation stress low to minimize the need for replacement retaining rings.
Regardless, Spirolox retaining rings should be carefully inspected before being re-used for signs of corrosion or deformation that may reduce performance. If in doubt we recommend replacing it with a new one.

Quick connectors

Appearing in the majority of the fluid transfer lines in the automotive market, ARaymond™ Quick Connectors provide solutions adapted to the constraints and requirements of today’s industries. Quick connectors bring many technical solutions for fluid connections in HVAC (Heating, ventilation and Air-Conditioning) and Sanitation responding to the applicable standard requirements of these sectors.

  • Manufactured in plastic for reduced weight end corrosion resistance
  • Helps meet environmental requirements / Emissions.
  • A very compact and short connector, easy for use.
  • Reduces assembly cycle time and increases productivity: no tool required to disconnect in aftermarket applications.
  • Variety of angles (0° - 30° - 35° - 45° - 55° - 65° - 90° - 3 way QCs), diameters (from 6,3 to 56mm), fluids (fuel, water, oil, air & vacuum...).
  • Variety of performances which depend on type of fluid, diameter, temperature (from -40 to +125°) and pressure (from -1 to +10 bars).
  • Versatility of our quick connectors: Integrated functions such as shut-off valve, calibrated valve, one-way-valve, pressure regulator valve, integrated pressure check valve.
  • Critical cleanliness guaranteed on all quick connectors.
  • Assembly proofing devices.

TFC's dedicated team of engineers can support your connector configuration. Please send all specifications and information relating to your operating conditions to design@tfc.eu.com

Smalley Talk

Part Numbers and repeat product use

Welcome back to the Smalley Talk engineering blog, where our engineers answer commonly asked ring and spring design questions. This week, Debbie Annets of our Technical Support Team fields questions about part identification and the re-usability of spirolox rings.

For more than 50 years, TFC has been growing to become a recognised industry leader in the supply of retaining rings, constant section rings and wave springs. Whether you require a standard part or a custom solution, our dedicated team of engineers can provide advice, and when required design a bespoke part to meet your specific application requirements.

Can Spirolox retaining rings be reused after they have been removed?

Smalley 2-turn spirolox retaining rings are specifically designed to take high axial loads yet can still be installed and removed easily. Depending on the installation method and installation stress, these rings can often be reused without any issues. If your application requires frequent installation and removal, it would be best to keep the installation stress low to minimize the need for replacement retaining rings.
Regardless, Spirolox retaining rings should be carefully inspected before being re-used for signs of corrosion or deformation that may reduce performance. If in doubt we recommend replacing it with a new one.

I have a Smalley part number listed but I can't find it in the catalogue or on your website, where can I find information about the part?

You may be looking for information on a custom design which is not published for general circulation. It is also possible that you may have an invalid TFC part number, an alternative supplier reference or an old number from a manufacturer who is no longer trading. For all these cases, the best solution is to contact a TFC Engineer.

Debbie Annets has worked with these products for over 10 years and is frequently faced with these questions. “we have an extensive database of part numbers and drawings that enable TFC to cross reference part numbers to ensure we quote and supply the correct part”  Failing that with a few design details, our engineers will be able to determine what design is associated with the particular part number and provide the appropriate information.

 

That’s all for now, in the next installment of Smalley Talk, we will help you to determine the life cycle of your springs. We will also answer a question about exotic materials. You can see more blog entries and other application examples on our technical articles page.
