Preload Springs, Spacers, and Washers Specifications

Help with Preload Springs, Spacers, and Washers specifications:

Type

	Your choices are...
	Belleville Washer		A Belleville washer is a round compact spring that has been pressed into a dish, then hardened and tempered.
	Bowed / Curved Washer		A bowed, or curved washer is a bent spring washer used for axial play take-up.
	Conical Washer		Conical washers provide great load bearing capacity. They are designed to provide a compensating spring force and sustain a load or absorb shock. Conical washers span holes and maintain high tension in screw and nut assemblies. They are available in plain or toothed periphery styles.
	Constant Force Spacer Courtesy of Temper Corporation		Constant force spacers, also called adjustable spacers or load rings, are used as a shim, wave spring or other spring washer replacement for assemblies requiring accurate bearing settings, including preload.  They are constructed of convoluted, ductile, high strength metal alloys and are available in machined, welded and open ring variations.
	Finger Washer		Resilient fingers on the outer periphery assure balanced pressure and directs the pressure away from the I.D.
	Wave Washer		Wave washers, also called wave springs, are wavy metal washers designed to provide a compensating spring force and sustain a load or absorb shock.

Size

	Inside Diameter		Inside diameter of washer.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
	Outside Diameter		Outside diameter of washer.
	Search Logic:		User may specify either, both, or neither of the "At Least" and "No More Than" values. Products returned as matches will meet all specified criteria.
	Thickness / Working Height		This dimension refers to either the thickness of the washer material, or the working height (installed height) for the product.  A flat washer has a constant thickness, while a spring washer can operate over a range of heights.

Material / Finish

	Metallic
	Your choices are...
	Aluminum		A bluish silver-white, malleable, ductile, light, trivalent, metallic element that has good electrical and thermal conductivity, high reflectivity, and resistance to oxidation.
	Brass		Brass comes with good strength, excellent high temperature ductility and reasonable cold ductility, good conductivity, excellent corrosion resistance, good bearing properties and low magnetic permeability.
	Copper Base Alloy / Bronze		A copper base alloy is metal composed of copper as the main alloying metal and one or more other metals, such as tin, zinc, or phosphorus.  Sintered bronze is a porous material, which can be impregnated with oil, graphite or PTFE. Sintered bronze is not suitable for heavily loaded applications but useful where lubrication is inconvenient.
	Copper		A common reddish metallic element that is ductile and malleable and is one of the best conductors of heat and electricity.
	Nickel Base Alloy		A nickel base alloy is a metal alloy composed of nickel and one or more other metals, such as copper.
	Spring Steel		Spring steel is any of a variety of steels that are normally of the high-carbon or alloy type.  They are used in the manufacture of springs because of their high tensile properties. The type of spring steel used depends on the application and type of spring. They range from plain carbon grades in the range 0.5% to 1.00% C., to chromium, chromium-vanadium, nickel-chromium-molybdenum, silicon-manganese and silicon-manganese-chromium-molybdenum types.
	Steel		A commercial iron that contains carbon in any amount up to about 1.7 percent as an essential alloying constituent. It is malleable when under suitable conditions, and is distinguished from cast iron by its malleability and lower carbon content.
	Hardened Steel		Steel may be hardened in a number of ways, including a variety of quenching techniques in oil and water, being passed through induction chambers, etc. Quickly cooling steel during processing freezes, traps and packs the carbon atoms inside the shrunken iron crystals, thereby producing a very hard and brittle metal. Although very hard, it cannot absorb much shock or impact without breaking.
	Stainless Steel		Stainless steel is chemical and corrosion resistant and can have relatively high pressure ratings.
	Titanium		Titanium is a hard, lustrous, silvery, element that is relatively abundant in the Earth's crust.  It is known for its lightness, strength, and corrosion resistance.  For this reason it is used widely in the aerospace industry and the medical fields (e.g., replacement joints).  When alloyed with other metals, especially steel, it adds strength and oxidation resistance.
	Other		Other unlisted, specialized, or proprietary metallic materials.

	Finish
	Your choices are...
	Anodize		Anodizing is a process for finishing aluminum alloys that employs electrolytic oxidation of the aluminum surface to produce a protective oxide coating. The anodic coating consists of hydrated aluminum oxide. It is considered resistant to corrosion and abrasion. Conventional coatings are 0.1 to 1.0 mil thick and are mostly transparent, but may be colored.  Anodizing preserves the natural luster, and texture of the metal itself. An anodized coating is hard, durable, will never peel, and, under normal conditions, will never wear through.  This category includes hard coat anodizing.
	Black Oxide		Black oxide is a conversion coating that causes virtually no dimensional change. It is a uniform continuous conversion of the existing metal to a black form of rust. Used primarily on components where tight tolerances are needed; mostly as a decorative coating.
	Phosphate		A coating produced by a chemical or electrochemical treatment of the metal surface.  The coatings provide corrosion resistance and provide a surface for better adhesion of primers and paints.
	Galvanized		Galvanizing is the practice of immersing clean, oxide-free iron or steel into molten zinc in order to form a zinc coating that is metallurgically bonded to the iron or steel surface. The zinc coating protects the surface against corrosion by providing protection to the iron or steel in two ways. It shields the base metal from the atmosphere and because it is more electronegative than iron or steel, the zinc reacts with corroding agents first, providing a longer service lifetime for the part.
	Nickel Plated		Applying a nickel surface to another material.
	Tin Plated		Applying a tin surface to another material.
	Zinc Plated		Applying a zinc surface to another material.
	Zinc Chromate		Applying a yellow zinc surface to another material.
	Other		Other not listed finish.
