Full Ceramic Bearings

Full ceramic bearings with every component — inner ring, outer ring, and rolling balls — is made from advanced ceramic materials: Silicon Nitride (Si₃N₄) or Zirconia (ZrO₂).

They deliver unmatched resistance to corrosion, extreme temperatures, chemicals, and wear. They run with ultra-low friction, often without any lubrication, making them ideal for environments where steel bearings quickly fail.

Whether you’re working in chemical processing, medical equipment, high-temperature furnaces, vacuum systems, or marine environments, these bearings provide longer service life and superior performance.

ZMS is a professional supplier of full ceramic bearings in China. We shall give you more attractive price and high quality full ceramic bearings products. Shorten delivery time and with rich stocking for some standard deep groove ball bearings in ceramic material.

We can offer:
Full ceramic deep groove ball bearings
Full ceramic self-aligning ball bearings

Feature

Extreme Temperature Resistance: Si₃N₄ versions handle up to 1,200°C+ (full complement design), while ZrO₂ reaches up to 1,000°C. Perfect for ovens, furnaces, and cryogenic applications where steel bearings soften or seize.
Complete Corrosion & Chemical Resistance: Fully immune to water, saltwater, acids, alkalis, and aggressive media. They perform reliably even when fully submerged or exposed to harsh chemicals — ideal for food processing, marine, semiconductor, and pharmaceutical use.
Ultra-Low Friction & High speed: Lower coefficient of friction enabling higher RPM normally 1.5-2 times than steel.
Lightweight & Non-Magnetic: 40–60% lighter than steel bearings. Non-magnetic and electrically insulating properties make them essential for MRI machines, sensitive electronics, sensors, and electric motors.
High Hardness & Wear Resistance: Exceptional durability extends service life dramatically in abrasive or high-speed conditions.
Vacuum Compatible: Excellent for semiconductor manufacturing and space applications.
