• Heat Stabilized 52100 Steel
• Steel Cage
• Service: -42 °C to 220 °C, intermittent 250°C
• ABEC-1
• C4 internal clearance
• Viton Seals
• HTB 550 High Temperature Grease

Designed to handle a combination of radial and axial forces at a range of speeds, temperatures, and environments for an extended period with minimal friction. Sealed units are protected from liquids, vapors, and fine dust, have excellent grease retention but have increased friction compared to shielded and open bearings. KX series ball bearings are designed to significantly outlast all other equivalently sized ball bearings in high-temperature service above 180°F up to their rated temperature. This is achieved with superior metallurgy, elastomers and lubrication selected explicitly for service in the specified temperature range.

• All Components Zirconium Oxide
• Full Ball Complement-No Cage
• Service: -80 °C to 400 °C
• ABEC-1
• Without Seals or Shields
• Runs Without Lubrication
• RoHS Compliant
• Constructed to be fully heat stable

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.

• All Components Silicon Nitride
• Full Ball Complement-No Cage
• Service: -80 °C to 800 °C
• ABEC-1
• Without Seals or Shields
• Runs Without Lubrication
• RoHS Compliant
• Constructed to be fully heat stable

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.
