Medical Bearings
Medical devices that require sliding, turning, and rolling depend upon bearings that operate efficiently. Medical bearings are designed for high speed applications in surgical and laboratory handpieces and equipment. Reliability and durability are essential in critical medical uses.
Manufactured to ABEC standards, precision miniature and instrument handpiece medical bearings are made from quality material:
- 440C stainless steel
- Silicon Nitride (ceramic)
- Titanium Carbide coated 440C
Designed as full-shoulder units, bearing retainer construction may include:
- stainless steel crown
- two-piece ribbon
- Teflon sealed stainless
See our supplier quality requirements.
The operating environment of medical handpieces subjects equipment to bone fragments, metallic chips, grinding debris, blood, and other liquids. This exposure along with chemical and heat sterilization processes can be costly to equipment. To increase bearing life medical bearings utilize such materials and designs as:
- Torlon (polyamide-imide)
- Phenolic
- shields
- anti-friction lubricants
- food-safe and autoclave resistant lubricants
Medical bearings in standard sizes can be ordered from stock for use by maintenance technicians. It is important to find engineering and design expertise to develop custom medical bearings that provide:
- instantaneous responsiveness
- varying load capacity
- intermittent operation
- long operating life
