MODIA® Precision Ceramic Bearings — Corrosion-Resistant, Non-Magnetic,
Electrically Insulated, High-Speed
Overview
Wuxi Maida Bearing Co., Ltd. (brand: MODIA®) supplies precision full ceramic
and hybrid ceramic bearings engineered for the most demanding operating
conditions — corrosive washdowns, high temperatures, high speeds, and
magnetic-sensitive environments where standard steel bearings fail early. From
compact 608-size bearings for high-speed equipment to custom non-standard
ceramic bearings for industrial machinery, every unit is manufactured to tight
tolerances and inspected before shipment.
Key Benefits (feature → benefit)
1. Superior corrosion resistance — Ceramic materials withstand seawater, most
acids and alkalis, and chemical environments where steel bearings rust quickly.
Ideal for marine, food processing, chemical, and plating equipment.
2. Electrically insulated — Ceramic is an excellent electrical insulator,
protecting motor bearings from shaft-current damage and fluting in VFD-driven
and inverter motors — a common cause of premature motor failure.
3. Non-magnetic — Safe for MRI equipment, electronic instruments, and other
magnetic-sensitive applications.
4. Higher speed, lower friction — Ceramic balls are harder, lighter, and
rounder than steel balls. Lower friction and better heat tolerance allow higher
rotational speeds and longer service life.
5. High-temperature capability — Operates reliably in high-temperature
environments (up to ~800 °C continuous for silicon nitride in oven/kiln
applications) where standard steel-and-grease bearings fail.
6. Lightweight — Silicon nitride is roughly 40% lighter than bearing steel,
reducing centrifugal load and extending life at high RPM.
7. Dry / low-lubrication operation — Full ceramic versions can run dry or with
minimal lubrication, suitable for vacuum and clean-room environments requiring
oil-free operation.
