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.
