Shaft Material



	Your choices are...
	Alloy Steel		Alloy steel has a primary advantage over carbon steel in that it has better hardenability properties. This allows for better durability when in use.
	Aluminum		A bluish silver-white malleable ductile light trivalent metallic element that has good electrical and thermal conductivity, high reflectivity, and resistance to oxidation.
	Carbon Steel		A strong, hard steel that derives its properties from the amount of carbon in the alloy.
	Composite		A shaft made from carbon fibers and resins to bond them tightly. The main advantage is composite shafts are lighter and save energy.
	Plastic		A general term used to include a variety of polymer type materials.
	Stainless Steel		Steel corrosion resistance results from formation of thin film of compound oxides that are snug against the metal surface and protect it from penetration of aggressive substances. Stainless steel is a corrosion resistant alloy of metals where the primary metal is Chromium in alloy with Nickel.
	Other		Other unlisted, specialized, or proprietary shaft material.

Specifications


	Shaft Diameter or Width		The dimension as measured across the shaft. Some shafts are square in shape but most are round.
	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.

	Maximum Length		The shaft length as specified by the user. Most shafts are manufactured to standard lengths and can be cut to a specific length to match customer needs.
	Search Logic:		All matching products will have a value greater than or equal to the specified value.

	Weight		The weight of the shaft per unit distance. For instance, 1 pound per foot length.
	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.

	Height (if applicable)		The distance from the guide or rail base to the center of the guide or rail.
	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.

	Hardness
	Your choices are...
	Rockwell 50 to 59		The Rockwell Hardness Test presses a steel or diamond hemisphere-conical penetrator against a test specimen and measures the resulting indentation depth. HRC is an application used on the following types of metal: Steel, hard cast irons, case hardened steel and other materials harder than 100 HRB.
	Rockwell 60 to 69		The Rockwell Hardness Test presses a steel or diamond hemisphere-conical penetrator against a test specimen and measures the resulting indentation depth. HRC is an application used on the following types of metal: Steel, hard cast irons, case hardened steel and other materials harder than 100 HRB.
	Rockwell 70 to 79		The Rockwell Hardness Test presses a steel or diamond hemisphere-conical penetrator against a test specimen and measures the resulting indentation depth. HRC is an application used on the following types of metal: Steel, hard cast irons, case hardened steel and other materials harder than 100 HRB.
	Brinell		The Brinell hardness test method consists of indenting the test material with a 10 mm diameter hardened steel or carbide ball subjected to a load of 3000 kg.
	Knoop		Knoop hardness is a method of measuring a material's hardness by its resistance to indentation. The method uses a precision diamond indenter and loads of 1 to 1000 gf.
	Rockwell Superficial		The Rockwell Superficial hardness test method consists of indenting the test material with a diamond cone (N scale) or hardened steel ball indenter. The force applied is 3000 gf.
	Rockwell HRA, HRB, HRD		Rockwell tests where the test tip is either a diamond cone or hardened steel ball indenter. These three tests are the more common used besides the HRC Rockwell test.
	Shore^®		Shore testers are ideal for use on plastics and elastomers.
	Vickers		The Vickers hardness test method consists of indenting the test material with a diamond indenter, in the form of a right pyramid with a square base and an angle of 136 degrees between opposite faces subjected to a load of 1 to 100 kgf.
	Search Logic:		Products with the selected attribute will be returned as matches. Leaving or selecting "No Preference" will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Coatings



	Your choices are...
	Anodized		Anodizing is a protective surface coating process usually used on aluminum to prevent corrosion. It also provides for a harder surface finish.
	Black Oxide		A coating used most commonly on steel or stainless steel parts as a protective coating while the parts are on the shelf. It helps to prevent ion corrosion.
	Ceramic		Ceramic coatings offer a highly wear resistant finish.
	Chrome		Chromium coatings on shafts provide for excellent corrosion resistance and low friction.
	Nickel		Nickel coating provides a hard, uniform finish that is corrosion resistance as well as low friction and has good wear resistance.
	Nitride Coated		Nitride coating of a surface makes it very hard and more resistant to corrosion.
	Teflon®		Teflon® refers to a class of fluoropolymer resins used for a wide variety of commercial applications. They are highly resistant to temperature, chemical reaction, corrosion, and stress cracking. Teflon is a registered trademark of DuPont Dow Elastomers.
	Other		Other unlisted, specialized, or proprietary shaft coatings.

Additional Operations



	Your choices are...
	Chamfered End		The one or both ends on the shaft are cut at an angle or beveled.
	Break Edge		Break edge is the procedure of removing any burrs and sharp edges on the ends of the shaft. It usually doesn't include chamfering the edges.
	Axial Holes		Holes that are drilled into the ends of the shaft. These are not tapped. If you want them to be tapped check the "Tapped Holes - Axial" selection in this section.
	Radial Holes		Holes that are drilled along the length of the shaft. These are not tapped. If you want them to be tapped check the "Tapped Holes - Radial" selection in this section.
	Male Threads		One or both ends of the shaft are cut with male threads.
	Tapped Holes (Radial)		Refers to any tapped holes along the shaft. Threads that are cut into the body of the shaft for mounting, attaching to supports.
	Tapped Holes (Axial)		One or both ends of the shaft are tapped with female threads.
	Grooved		Grooving on the shaft allows for the placement of snap rings. These are usually located at the ends of the shafts but could be placed anywhere on it.
	Keyed		A portion or all of the shaft is channeled for a keyway.
	Precision Ground		A grinding finish to the surface of the shaft that is designated to some precision by the manufacturer.
	Stepped End		A machining operation at the end of a shaft where the diameter "steps" down to a smaller diameter.
	Other		Other unlisted, specialized, or proprietary additional operations.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.

Special Features



	Your choices are...
	Unhardened / Annealed		A shaft that is left unhardened in any manner or has been heat treated so that the entire piece is annealed.
	Annealed Ends		Only the end portions of the shaft are annealed while the remainder is left hardened.
	Case Hardened		It is the process of changing mild or soft steel into a very hard steel by using carbon or nitrogen. Typically, only the surface of the steel is affected and the core material remains relatively soft.
	Through Hardened		The entire shaft is hardened to the same hardness.
	Solid Shaft		A shaft of steel that is not hollow and has been case hardened.
	Tubular Shaft		A tubular shaft has a hollow center and has been case hardened.
	Standard Grade		A standard grade shaft is one where the tolerances for straightness and roundness are not very tight.
	Precision Grade		One of two grades of precision shafting and having a tightly rated tolerance for roundness and shaft straightness per unit length.
	Ultra Precision		One of two grades of precision shafting and having a very tight tolerance in over all straightness and roundness.
	Other		Other unlisted, specialized, or proprietary features.
	Search Logic:		All products with ANY of the selected attributes will be returned as matches. Leaving all boxes unchecked will not limit the search criteria for this question; products with all attribute options will be returned as matches.
