Engineered to exceed standard industry expectations, our 695 series brings exceptional reliability to the most intricate mechanical environments. By focusing on the exact pain points of assembly designers—such as excessive heat generation and premature wear—we have developed a component that actively enhances the lifespan of your products.
Acoustic Excellence: Achieves strict Z1 and Z2 noise levels, ensuring your final consumer products operate with a premium, silent hum rather than disruptive mechanical clatter.
Thermal Stability: The optimized internal geometry minimizes friction-induced heat, keeping surrounding sensitive electronic components safe from thermal degradation.
Energy Efficiency: The ultra-low starting torque translates directly into longer battery life for portable devices and lower power draw for wired motor systems.
Structural Rigidity: Despite its miniature footprint, the robust raceway design effortlessly handles light to moderate radial loads without suffering from micro-deformations.
The architectural foundation of the 695 bearing is its highly controlled physical footprint. Measuring exactly 5x13x5mm, this ultra-compact component is meticulously crafted to fit into the most restricted housing spaces without compromising on load-bearing capabilities. This precise sizing empowers engineers to design sleeker, lighter, and more aerodynamic equipment.

Chamfer Precision: A strictly maintained 0.3mm minimum corner radius guarantees seamless seating within the housing, eliminating the risk of installation misalignments.
The longevity of any rotational system is dictated by its metallurgical integrity. We construct our 695 bearings using premium Chrome Steel (GCr15) or high-grade Stainless Steel, subjecting each batch to rigorous, controlled heat treatments. This creates a surface that feels glass-smooth to the touch yet possesses the underlying hardness required to resist continuous metal-to-metal fatigue.
Wear Resistance: Advanced heat treatment hardens the raceways, drastically reducing the risk of spalling or pitting over millions of high-speed rotational cycles.
Corrosion Mitigation: The stainless steel variant offers exceptional defense against ambient moisture, protecting your investment in humid or chemically active environments.
Grinding Perfection: Precision-ground surfaces minimize microscopic asperities, resulting in a flawless rolling contact that extends the time between required maintenance intervals.
Cage Resilience: Available with high-performance polymer cages that resist degradation from synthetic lubricants and withstand severe high-speed centrifugal forces.
When your application demands absolute exactness, the performance metrics of the 695 bearing deliver uncompromising results. Calibrated to ABEC-5 and ABEC-7 precision grades, these bearings provide a rotational fluidity that eliminates runout and maintains strict shaft centering. This level of precision is critical for applications where even a fraction of a millimeter of deviation can cause catastrophic system failure.
Extreme Velocity Handling: Capable of reaching up to 42,000 RPM in the open configuration, supporting ultra-fast micro-turbines and high-speed spindles without seizing.
Vibration Eradication: High precision grades ensure that rotational kinetic energy is transferred smoothly, preventing harmonic vibrations from disrupting sensitive optical or sensor arrays.
Consistent Torque Delivery: The low starting and running torque guarantee that your motors do not experience sudden, damaging spikes in electrical current demand.
Clearance Optimization: Options for C0, C2, and C3 radial clearances allow you to perfectly match the bearing to your specific thermal expansion and load requirements.
Environmental contamination is the primary enemy of bearing longevity. To safeguard the intricate internal geometry of the 695 bearing, we offer a comprehensive suite of shielding and sealing technologies. Whether your equipment operates in a sterile laboratory or a dust-filled workshop, these protective barriers ensure the internal lubricant remains pristine and highly effective.
Open Architecture: Ideal for sealed, clean-room environments where external lubrication systems are utilized, allowing for maximum speed capabilities up to 42,000 RPM.
Metal Shields (ZZ): Dual metal shields provide a robust defense against airborne particulates and larger debris, perfect for standard industrial automation settings while maintaining a high speed limit of 32,000 RPM.
Rubber Seals (2RS): The contact rubber seals create an impermeable barrier against moisture and fine dust, essential for outdoor devices or washdown environments, supporting speeds up to 22,000 RPM.
Lubricant Retention: Both ZZ and 2RS variants lock in the factory-applied premium grease, creating a reliable, maintenance-free component for the entirety of its operational life.
The versatile nature of the 695 miniature bearing makes it an indispensable asset across a multitude of advanced sectors.

The ABEC-7 grade offers significantly tighter dimensional tolerances and lower radial runout compared to ABEC-5. This results in smoother operation, reduced vibration, and the ability to maintain stability at the absolute maximum speed limits. ABEC-7 is highly recommended for ultra-precise instrumentation and optical devices, whereas ABEC-5 is excellent for standard high-speed motors and general automation.
Sealing types introduce different levels of physical friction. The Open type has no seals, offering zero friction and allowing speeds up to 42,000 RPM. The ZZ (metal shield) creates a minimal non-contact barrier, slightly reducing the limit to 32,000 RPM. The 2RS (rubber seal) makes physical contact with the inner ring to block moisture and fine dust, which increases friction and limits the maximum speed to 22,000 RPM.
While deep groove ball bearings like the 695 are primarily engineered to support radial loads (up to ~0.70 kN dynamically), their deep raceway geometry allows them to accommodate light axial (thrust) loads in both directions. However, for applications with heavy, continuous, or shock axial loads, a different bearing configuration may be required to prevent premature raceway fatigue.
Chrome Steel (GCr15) is the industry standard, offering exceptional hardness, high load capacity, and excellent wear resistance for general indoor or sealed applications. Stainless steel should be selected when the bearing will be exposed to high humidity, corrosive chemicals, or when used in medical and food-grade environments where rust prevention is paramount, even though it possesses a marginally lower load capacity than chrome steel.
Radial clearance dictates the internal space between the balls and the raceways. C0 is standard for normal ambient conditions. C2 provides a tighter fit for precision applications with minimal vibration but generates more internal heat. C3 offers a larger internal clearance, which is absolutely critical for high-temperature environments or extreme high-speed operations where thermal expansion of the metal occurs, preventing the bearing from seizing as it heats up during operation.
