| ||
| Precision Grade | |||
| Your choices are... | |||
| 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. | ||
| 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. | ||
| |||
| 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. | ||

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. | ||
| Carbon Steel | A strong, hard steel that derives its properties from the amount of carbon in the alloy. | ||
| 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. | ||

| |||
| Hardness | |||
| 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. | ||
| 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. | ||

Coatings
Back to Top
|
|
| ||
| 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
Back to Top
|
|
| ||
| 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. | ||
| 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. | ||
