Zirconia-Single Row Angular Contact Bearings

Overview of Zirconia Single Row Angular Contact Bearings

Zirconia single row angular contact bearings are precision-engineered full ceramic bearings with both rings and rolling elements made entirely from zirconium dioxide (ZrO₂). These bearings are designed to support combined axial and radial loads, thanks to their angular contact configuration, and are particularly suited for use in aggressive environments where traditional steel or hybrid bearings would fail.

Key Features

• High Temperature Resistance: Operates reliably up to 400 °C without thermal degradation, suitable for ovens, furnaces, and high-heat production lines.
• Corrosion Resistance: Excellent chemical stability allows performance in acidic, alkaline, or salt-laden environments.
• Non-Magnetic: Suitable for use in magnetic-sensitive equipment such as MRI machines and electronic assembly tools.
• Electrical Insulation: ZrO₂ is a non-conductive ceramic, preventing current leakage or electrical damage in sensitive systems.
• Single Row Angular Contact Design: Supports axial and radial loads in one direction, ideal for high-speed and high-precision applications requiring thrust load capacity.

Performance Advantages

The use of zirconia as a bearing material offers several key performance enhancements over steel:

• Lower friction coefficient compared to steel, reducing wear and heat generation.
• Longer service life in corrosive or high-temperature environments.
• Minimal lubrication needs, with the option to run dry in certain low-load, clean environments.

Typical Applications

Medical Devices

Because they are non-magnetic and biocompatible, zirconia bearings are widely used in MRI-compatible systems, surgical tools, and dental devices.

Chemical and Laboratory Equipment

Used in pumps, mixers, and centrifuges exposed to aggressive chemicals, where conventional bearings corrode quickly.

High-Temperature Machinery

Ideal for kiln conveyors, thermal processing lines, and electronic manufacturing where elevated temperatures are routine.

Precision Spindles and Robotics

Offers low friction and long-lasting operation under moderate loads in ultra-clean and controlled environments.
