We offer materials such as: aluminum, all grades of steel, stainless steel, bronze, brass, Teflon, nylon and more. Diamond Fasteners is also a certified distributor of military standard bushings; including metric & AN, MS, NAS & NASM compliant bushings used in industrial applications. Military standard Bushings are available in stock of different sizes & materials. Military standard Bushings can also be customized as per size specifications.

The ABEC scale is an industry accepted standard for the tolerances of a ball bearing. It was developed by the Annular Bearing Engineering Committee (ABEC) of the American Bearing Manufacturers Association (ABMA). There are five classes from largest to smallest tolerances: 1, 3, 5, 7, and 9. The higher ABEC classes provide better precision, efficiency,[citation needed] and greater speed capabilities, but not make the components spin faster.[1] The ABEC rating does not specify many other critical factors, such as smoothness of the rolling contact surfaces, ball precision or quality/type of steel used. The bearing material is not specified in the ABEC grades. Military standard bearings not conforming to at least ABEC 1 cannot be classified as precision bearings as their tolerances are too loose. The scale is designed to allow a user to make an informed decision about the type of bearing they are purchasing. High rated bearings are intended for precision applications like aircraft instruments or surgical equipment. Lower grades are intended for the vast majority of applications such as vehicles, mechanical hobbies, skates, fishing reels and industrial machinery. High ABEC rated bearings allow optimal performance of critical applications requiring very high RPM and smooth operation. ISO's equivalent standard is ISO 492.[2][3] All military standard bushings and bearings are dfar complaint.
