115 105 683 Ceramic Ball Bearings With Superior Chemical Inertness Low Thermal Expansion Silent

Selection of Ceramic Ball Bearings Models

Our company currently produces five main categories of ceramic bearings, namely: high-temperature resistant bearings, corrosion-resistant bearings, high-speed bearings, anti-magnetic and electrically insulated bearings. These are available in four precision grades: P4, P5, P6, and P0.

Bearing Selection Guide

(1) High-temperature resistant bearings can operate within a temperature range of 200 °C to 1000 °C.

(2) Corrosion-resistant bearings can be used in various media, including:  
① Strong acids such as sulfuric acid, nitric acid, and hydrochloric acid;  
② Strong alkalis such as sodium hydroxide and potassium hydroxide;  
③ Inorganic and organic salts, as well as seawater.

(3) High-speed bearings are suitable for applications with DmN values ≤ 3 × 10⁶, such as high-speed grinding heads, high-speed spindle bearings, and other non-standard equipment.

(4) Anti-magnetic bearings can be applied in various magnetic isolation and anti-magnetic machinery and equipment, such as CT scanners and electrolytic grinding machines.

(5) Electrically insulated bearings can be used in mechanical equipment requiring electrical insulation.
