Model number: 19.05 mm 19.844 mm 20 mm 20.637 mm 22.225 mm 25.4 mm 38.1 mm Surface roughness: Ra 0.05 Structure: Loose Ceramic Ball Torque capacity: inch Material: ceramic; coatings: Si3N4 › See more product details; Product description Silicon Nitride Ceramic Balls Description: Silicon nitride (Si3N4) ceramic balls are made of a new material suitable for applications where high loads, high speeds and extreme temperatures are factors. Long service life and the need for minimal lubrication make this material suitable for extreme applications. Silicon nitride is non-magnetic, non-corrosive, lighter than steel and in ball shape, is harder than steel. As ceramic balls are non-porous. TheyTheyTheyTheyTheyTheyTheyand capable of spiders faster than steel balls. Its properties are shown as follows: 1. High corrosion resistance, which means they can also be used in strong acid, strong alkali and sea water. 2. High temperature resistance. Si3N4 ceramic balls remain the same strength and hardness even in 1100 °C. 3. Electrical insulation, non-magnetic, they can also be used in magnetic domain. 4. Si3N4 ceramic balls have a low density of 3.26 g/cm3. It is about 60% lighter than steel balls, which extremely reduce the centrifugal force on the groove to effectively reduce wear. 5. High rigidity and strength. Compared with bearing steel, ceramic Si3N4 is double higher hardness and higher half the elasticity module value. 6. The heat expansion coefficient of Si3N4 is 3.2 × 10-6 / K. It is almost 25% of the bearing steel, resulting in good heat shock resistance. 7. Self-lubricating Si3N4 ceramic ball bearings can help to loosen contamination and uncomfortable caused by oilers, it can also be used in a vacuum and high temperature conditions. 8. Low thermal conductivity. Areas of application: High-precision ceramic bearings, high temperature bearings, vacuum bearings, non-magnetic bearings, chemical pumps, high temperature pumps, valve balls ceramic balls and to measure.; Product description Silicon Nitride Ceramic Balls Description: Silicon nitride (Si3N4) ceramic balls are made of a new material suitable for applications where high loads, high speeds and extreme temperatures are factors.
