Bearings for Medical Application
MMB stocks a wide assortment of bearings designed to the demanding applications of the medical industry, including surgical and dental tools, diagnostic and laboratory equipment, pumps and much more.
When choosing bearings for medical devices & medical applications, several factors should be considered including speed, low noise, service life, and resistance to harsh environments, aggressive chemicals, or fluids. As a stocking distributor of NMB precision miniature ball bearings, we have thousands of bearings ready to ship to you.
Materials used for medical instruments bearings include:
- AISI 440C
- Nitrogen enhanced stainless steel
- Ceramic materials
- Stainless Steel 300 series
- 52100 Bearings steel
- Instrument Miniature Ball Bearings- Although these are two different categories, they are generally the same. The miniature bearing must fall within a specific size to qualify as a miniature bearing. The instrument bearing does not have to fall within a specific size range but covers a lot of the miniature bearings. The instrument bearings must be ABEC 5 or greater and have specific characteristics that miniature bearings are not required to have. These include having uniform running torque, smooth operation and limits on the amount of vibration, a definite contact angle or preload (or both), and these are required to have very high cleanliness standards.
