Sealed units are protected from liquids, vapors, and fine dust, have excellent grease retention but have increased friction compared to shielded and open bearings. Sealed units are protected from liquids, vapors, and fine dust, have excellent grease retention but have increased friction compared to shielded and open bearings. Zirconia offers high strength, wear resistance, and flexibility. It has a superior surface hardness, the highest level of impact toughness for a bearing grade ceramic, corrosion resistance, elastic modulus and thermal expansion similar to bearing steel, and good high-temperature performance. It has low thermal conductivity, is electrically non-conductive and non-magnetizing, making it a suitable material to replace metals in many applications where isolation is essential. One notable weakness is high-temperature steam will degrade Zirconia.

• Highly corrosion resistant
• ROHS compliant
• ABEC-1

Sealed units are protected from liquids, vapors, and fine dust, have excellent grease retention but have increased friction compared to shielded and open bearings. Silicon Nitride has a good combination of mechanical, thermal, and electrical properties. It is extremely hard and has exceptional thermal shock, impact resistance, and high-temperature capabilities, with high creep, oxidation, and wear resistance but is exceptionally light in weight. Its low thermal and electrical conductivity is especially useful in applications where corrosion, electric or magnetic fields prohibit the use of metals. It is an excellent choice when high-temperature and high-load abilities are needed. However, it has a very low rate of thermal expansion that must be accommodated to prevent excessive tensile stress on the inner race.

• Silicon Carbide races and balls
• PEEK Cage
• Service: -70 °C to 250 °C
• .0005 inch internal clearance
• PTFE seals
• Maximum corrosion resistance
• Semi-conductor
• ROHS compliant
• ABEC-1

Sealed units are protected from liquids, vapors, and fine dust, have excellent grease retention but have increased friction compared to shielded and open bearings. Silicon Carbide is one of the lightest and hardest ceramic materials. It has exceptional thermal conductivity, resistance to acids, and low thermal expansion. It is an excellent material to use if exposure to particle wear is a primary concern; it exhibits excellent erosion and abrasive resistance. Silicon carbide is not attacked by any acids, alkalis, or molten salts up to 800°C. In the air, above 2192 °F (1200 °C), SiC begins to form a silicon oxide coating that is protective of the material but undesirable for precision bearings, limiting the material's maximum use temperature as a bearing. The high thermal conductivity, coupled with low thermal expansion and high strength, provide exceptional resistance to thermal shock. It is a semiconductor. Dielectric performance should be verified if electrical isolation by the bearing is required.
