Smalley's Metric Crest-to Crest series are available in dimensions from 6 to 60 mm.Crest-to-Crest springs enable original equipment manufacturers to reduce the size of their assembly by up to 50% while maintaining the same amount of force and deflection as a regular coiled spring. Crest-to-Crest wave springs minimize assembly cost and total assembly size due to the reduced spring cavity required. Available in carbon and stainless steel from stock.

Single turn wave springs are ideal for bearing preload. The wave spring preloads the bearing through its outer race, taking up play in the bearing. By preloading a bearing, you will reduce bearing damage and wear. This particular application benefits from the wave spring by preventing sliding between the rolling elements.
Smalley’s Bearing Wave Spring Series comes in metric sizes to match popular bearing sizes. Smalley has over 150 standard bearing springs available, ranging from 16mm to 580mm. Specials are available for unique bearing sizes with No-Tooling-Charges™.

Crest-to-Crest Wave Springs can replace conventional round wire springs while occupying only half the space. Crest-to-Crest Springs offer the same force and deflection as standard coil springs.
Crest-to-Crest springs are stocked in a wide variety of loads and deflections; standard parts are available from 3/8” to 16”. Special designs can be from .200” to 90”; specials are affordable because of Smalley’s No-Tooling-Cost™ process.

Disc springs are conically-shaped, washer-type components designed to be axially loaded. What makes disc springs unique is that based on the standardized calculations of DIN 2092, the deflection for a given load is predictable and the minimum life cycle can be determined. Disc springs can be statically loaded either continuously or intermittently, or dynamically subjected to continuous load cycling. They can be used singularly or in multiples stacked parallel, in series or in a combination thereof.
- A wide range of load/defl ection characteristics
- High load capacity with small defl ection
- Space savings - high load to size ratio
- No set under design loads
- Longer fatigue life
- Inherent dampening especially with parallel stacking
- Flexibility in stack arrangement to meet your application requirements

Motor springs can be configured in many different ways. In some, the spring is wound in the same direction around the larger torque output drum. In others, the spring is bent in the opposite direction. This configuration stores more energy per weight of spring but does reduce the fatigue performance.
|

The NEG'ATOR extension spring represents the most basic, yet most versatile, type of constant force springs. It is a prestressed flat strip of spring material which is formed into virtually constant radius coils around itself or on a drum. When deflected, the spring material straightens as it leaves the drum. This straightened length of spring actually stores the spring's energy through it's tendency to assume its natural radius.
The full rated load of the spring is reached after being deflected to a length equal to 1.25 times its diameter. Thereafter, it maintains a relatively constant force regardless of extension length. Load is basically determined by the thickness and width of the material and the diameter of the coil.
Fatigue life of NEG'ATOR springs ranges from 2,500 cycles to over a million cycles depending upon the load and size of the spring. Working deflections of 50 times the drum diameter can be achieved. A wide variety of mounting configurations can be used such as cavity mounts, multiple spring mounts, etc., depending on the application. End connections can also be varied to fit the design situation. Hunter's own experienced engineers can help you select a spring design to meet your space, life cycle, load and operation requirements.

Enormous extendibility of constant force in excess of 50 times the relaxed length can be achieved.
The original concept of constant force springs was Extension Springs for counterbalancing windows For many years this has been a perfect aid in the opening and closing of windows from residential applications to black taxi cabs through to Rolls Royce and Aston Martin cars.
Constant force extension springs provide a huge range of application opportunities. Springs can be can be mounted on a bobbin or bush or free running in a cavity or recess. Springs can be joined or laminated to provide increased force with minimal increases in space requirements.

DETAILS OF CONSTRUCTION
RINGFEDER® Friction Springs consist of a series of separate inner and outer rings with mating taper faces. Under the application of an axial load F the wedge action of the taper faces expands the outer rings and contracts the inner rings radially, allowing axial deflection.
An effective taper face i.e. one half inner ring and one half outer ring is defined as one element.
The rings are manufactured from high quality spring steel. They are rolled or turned, calibrated for size, hardened and tempered. The rings are then given a final dimensional check.
Before despatch, every complete spring is mounted according to the assembly drawing, several times block loaded and checked against diagram data.
CHARACTERISTICS OF RINGFEDER® FRICTION SPRINGS
1. Absorption/damping of high kinetic energies
2. Absorption of high kinetic energies at small component sizes
(e.g. overload protection)
3. Versatility in design
4. High spring work combined with low weight and volume
5. Overload-safe in blocked position
6. Characteristics independent of loading rate
7. Diagram independent of temperature
8. Parallel and series arrangement of springs
9. Force-travel Diagram

Very high constant torque can be obtained by laminated R.W. springs through 90º angular movement.
A development from motor springs is the maximum energy torque spring or EB-RW. Essentially a short motor spring which generally consists of two or more spring laminations (up to 8 in each assembly) depending on the torque required and space limitations.
|
|
Long running motors of 50 turns or more at near constant torque can be achieved.
Typically used for retrieving and returning, the motor spring has many uses.
Motor springs can be configured in many different ways. In some, the spring is wound in the same direction around the larger torque output drum. In others, the spring is bent in the opposite direction. This configuration stores more energy per weight of spring but does reduce the fatigue performance.

SPIR'ATOR® Prestressed Spiral Springs
The SPIR'ATOR prestressed spiral spring is produced by reverse winding a NEG'ATOR on an arbor and enclosing it in a case. Rotational energy can be obtained from either the arbor or case or, when linear motion is required, through use of a pulley and cable attachement.
The unique design of this encapsulated spring yields a compact power source which operates with higher working stress and can provide more than twice as many revolutions as a conventional power spring in the same size case. With torque and deflection being equal, a SPIR'ATOR generally requires 20% less space than a power spring. Most importantly, this power package creates a low torque gradient.
|
|
Centrally winding, power springs offer high torque possibilities within confined spaces.
With springs ranges from 2mm in width and .05mm in thickness, Spiroflex represents the leading force in retraction systems, from inertia seatbelts and domestic vacuum cleaner cord retractors to dog leads and tape measures.
Almost all applications are bespoke; products are designed and developed in conjunction with our customers to suit the specific requirements of their application.
Spiroflex can supply products mounted into customers components, plastic housings or keeper rings, dependant upon design they can also be produced ‘pre wound’ to aid assembly on the customers production lines

A tightly coiled wound band of pre-hardened spring steel or stainless steel strip. When extended a constant force is exerted and this is maintained as the spring is allowed to close. The full force is effective until the spring is in the fully closed position.
This spring type derives its name from its ability to extend through its full working length while being maintained in any position by the same force. Constant force springs are available in a wide variety of sizes and the recent introduction of a purpose built plant ensures the price competitiveness of the smallest production run. Emmotts is one of the UK's most experienced manufacturers in this highly specialised field.
