Cage-less silicon nitride deep groove ball bearing for high-load, high-speed, and extreme-temperature applications.
The CE-6007-Si3N4-V is a high-precision full ceramic deep groove ball bearing featuring Si₃N₄ (silicon nitride) rings and balls with a full complement (cage-less) design. Si₃N₄ bearings leverage silicon nitride's exceptional strength, thermal shock resistance, and low friction, making them ideal for high-speed, high-load, and extreme-temperature applications. The absence of a cage allows for a maximum number of rolling elements, providing higher radial load capacity and eliminating cage-related failure modes at elevated temperatures.
With a standard envelope of 35 mm bore, 62 mm outside diameter and 14 mm width, this bearing is dimensionally interchangeable with standard 6007 steel bearings. The full complement design and Si₃N₄ material enable reliable operation in demanding environments where conventional bearings may fail. Widely used in aerospace, automotive, and precision machinery for superior performance.

Silicon nitride offers exceptional strength, high hardness (HV 1500), and excellent thermal shock resistance. It is lighter than steel (density ~3.2 g/cm³), electrically insulating, non-magnetic, and highly resistant to wear and corrosion.
The cage-less, full complement design maximizes the number of Si₃N₄ balls, increasing radial load capacity and eliminating cage-related failures at high temperatures or in vacuum.
Si₃N₄ maintains its mechanical properties at elevated temperatures. The absence of a polymer cage allows operation across a wide temperature range, with dry running capability.
Si₃N₄ is extremely resistant to acids, alkalis, and corrosive media, making this bearing suitable for chemical processing, food-grade, and other harsh environments.
The low density of Si₃N₄ reduces centrifugal forces, enabling high rotational speeds. The open, dry-running design supports operation without grease or oil, reducing maintenance and contamination risks.
*Actual operating temperature and speed limits should be confirmed according to the complete bearing configuration and application conditions.
● Aerospace — actuators, turbine components, and flight control systems requiring lightweight, high-temperature stability and reliability.
● Automotive — electric vehicle motors, turbochargers, and fuel pumps demanding high-speed capability and corrosion resistance.
● Precision Machinery — high-speed spindles, machine tool bearings, and grinding spindles requiring high rigidity and accuracy.
● Chemical & Food Processing — pumps, agitators, and mixers exposed to aggressive chemicals, with food-grade compatibility.
● Semiconductor & Cleanroom — vacuum robots, wafer handling, and precision equipment requiring non-magnetic and non-conductive components.
● High-Temperature Equipment — furnaces, kilns, and heat-treatment lines where conventional lubricants fail.

If the standard CE-6007-Si3N4-V configuration does not meet your requirements, send TOJO your operating conditions and bearing specifications for evaluation.
The bearing has a 35 mm bore, 62 mm outside diameter and 14 mm width, with a reference weight of approximately 63 g.
The "V" suffix indicates a full complement (cage-less) design. This configuration maximizes the number of Si₃N₄ balls, increasing radial load capacity and eliminating cage-related failure modes.
Si₃N₄ (silicon nitride) offers higher hardness, better thermal shock resistance, and lower density, making it preferred for high-speed and high-temperature applications. ZrO₂ (zirconia) offers higher fracture toughness and is often chosen for corrosive environments.
This bearing is supplied in a dry (lubrication-free) condition. The open design and full complement structure support operation without grease or oil in many applications, particularly in vacuum, cleanroom, and high-temperature environments.
