The 695 Zirconia Full Ceramic Bearing is a precision miniature deep-groove ball bearing engineered with rings and rolling elements manufactured entirely from zirconium dioxide (ZrO₂) ceramic, paired with a PTFE (polytetrafluoroethylene) retainer as standard configuration. The bearing conforms to metric size 695: 5mm inner diameter × 13mm outer diameter × 4mm width. Its all-ceramic construction delivers superior electrical insulation, non-magnetic properties, corrosion resistance, and self-lubricating characteristics, making it an ideal replacement for conventional steel bearings across demanding applications.
Zirconia (ZrO₂) is an advanced ceramic material whose unique physical and chemical properties underpin the superior performance of full ceramic bearings.
Zirconia ceramic attains hardness up to 1200 HV, significantly exceeding that of bearing steel (approximately 700-800 HV). Under sustained high-speed rotation and repeated contact motion, the hard ceramic surface effectively resists abrasive wear, maintaining dimensional accuracy and operational stability. Ceramic bearings typically deliver 3 to 5 times the service life of steel bearings.
Zirconia exhibits outstanding chemical stability, resisting attack from strong acids, alkalis, inorganic salts, and seawater. While conventional steel bearings rapidly corrode in chemical processing, electroplating, and marine environments, zirconia full ceramic bearings operate reliably without protective coatings.
Zirconia ceramic is a natural insulator with high electrical resistivity, preventing arc damage to bearing raceways and rolling elements. Additionally, its non-magnetic nature prevents the attraction of magnetic particles, eliminating premature spalling and noise caused by contaminant ingress.
Zirconia ceramic exhibits a low coefficient of friction and inherent self-lubricating behavior. In ultra-high vacuum or environments where conventional lubrication is impractical, full ceramic bearings continue to operate reliably through the material's intrinsic lubricity.
Zirconia has a low coefficient of thermal expansion (approximately one-third that of steel), maintaining dimensional stability from 100°C to 600°C without significant thermal distortion. At cryogenic temperatures (e.g., -30°C), ceramic materials retain their mechanical properties.
Zirconia ceramic density is approximately 6.0 g/cm³, compared to 7.8 g/cm³ for bearing steel. The 695 full ceramic bearing weighs approximately 1.9 grams—about 76% of the equivalent steel bearing (≈2.5g). Lower mass translates to reduced centrifugal inertia.
The all-ceramic construction enables exceptional rotational speed potential. The 695 bearing achieves oil-lubricated limiting speeds up to 53,000 rpm, substantially exceeding comparable steel bearings. The low density, low friction coefficient, and favorable elastic modulus of ceramic materials effectively suppress heat generation and vibration at high speeds.
The 695 full ceramic bearing performs reliably under the following extreme conditions:
Zirconia ceramic bearings deliver 3 to 5 times the service life of steel bearings. With a dynamic load rating of 1.35 kN and static load rating of 0.52 kN, combined with ceramic wear resistance, the 695 significantly reduces downtime, spare parts inventory, and scrap rates.
The finely polished ceramic rolling contact surfaces minimize friction and operating noise, achieving reductions of 2-3 dB compared to conventional ball bearings. This makes the bearing ideal for precision instruments, optical devices, and high-speed spindles where vibration control is critical.
The 695 zirconia full ceramic bearing is widely used in:
Ceramic materials exhibit low thermal expansion, high elastic modulus, but lower fracture toughness than steel—requiring careful attention during installation. Recommendations:
