Medical & Dental Bearings
Our ISO Class 6 cleanroom gives us a distinct advantage in the support of medical applications which often require specialized greases and/or specific lubrication fill rates. In addition to medical devices, we can support dental hand-piece bearings as well as many other bio and life science platforms.
Medical & Dental Bearing Application Solutions
Precision Bearings for Critical Applications
When reliability is non-negotiable, we provide high-performance medical and dental bearings designed for the strict demands of surgical, diagnostic, and dental applications. These precision components ensure smooth, quiet operation at high speeds, with exceptional durability in sterilization environments.
Applications for Medical & Dental Bearings
Our high-performance bearings are engineered for demanding use in a wide range of medical and dental devices, where precision, cleanliness, and reliability are critical:
Dental Handpieces (High-Speed Turbines)
Bearings in dental turbines must support speeds over 400,000 RPM with minimal noise and vibration. We supply hybrid ceramic and miniature angular contact bearings designed to resist repeated autoclaving, reduce friction, and ensure long service life for both air-driven and electric handpieces.
Surgical Power Tools
From bone saws to high-speed drills and reamers, surgical tools require sterilizable, corrosion-resistant bearings that can operate under high loads and vibrations. Our bearings ensure reliable operation in powered surgical handpieces, offering precise control and extended cycle life.
Imaging Equipment
Precision is paramount in imaging systems like MRI machines, CT scanners, and ultrasound devices. Our low-noise instrument bearings reduce mechanical interference and support smooth, quiet rotation in motors, gantries, and articulated arms—often in magnetic or high-purity environments.
Blood Pumps & Centrifuges
Used in dialysis machines, lab centrifuges, and heart-assist pumps, these applications demand bearings that can withstand continuous operation, fluid exposure, and rigorous cleanliness standards. Our full ceramic and hybrid bearings offer excellent chemical resistance, low particle generation, and high-speed stability.
Prosthetics & Mobility Aids
From robotic limbs to wheel systems in powered wheelchairs, our miniature and deep groove bearings provide smooth motion, low rolling resistance, and durability in compact assemblies. These components support enhanced mobility and patient comfort in assistive technologies.
Types of Medical & Dental Bearings We Offer
We supply a wide range of bearing types tailored for medical and dental use:
Ceramic Hybrid Bearings
Silicon nitride balls with stainless steel races—ideal for high-speed, low-friction applications like dental turbines.
Full Ceramic Bearings
Non-conductive, corrosion-resistant, and sterilization-friendly—used in high-purity environments.
Stainless Steel Bearings
Precision-ground for resistance to corrosion and high-temperature steam sterilization.
Angular Contact Bearings
Provide high axial load capacity and speed, used in dental turbines and surgical tools.
Miniature & Instrument Bearings
Designed for low noise and precision, suitable for diagnostic equipment and small motors.
