Home Appliance Bearings | 1-15mm Miniature - Nova Bearing 

Miniature Precision Bearings for Home Appliances & Personal Care Devices

At Nova Bearing, we specialize in manufacturing high-precision miniature and small deep groove ball bearings with inner diameters ranging from 1mm to 15mm. Our core product line includes the 60, 62, 63, 68, and 69 series, engineered to meet the strict demands of household appliances and personal care devices.

1. Electric Toothbrushes

Electric toothbrushes rely on ultra-compact, reliable bearings to power high-frequency vibrations and rotational movements. Our 68 and 69 series thin-section bearings (2mm-4mm bore) are widely used in these slim, water-resistant devices. Their small footprint fits perfectly into limited internal space, while low-friction, corrosion-resistant performance ensures smooth, quiet operation through millions of use cycles.

2. High-Speed Hair Dryers

Professional-grade hair dryers operate at extremely high speeds, requiring bearings that can handle both high RPMs and elevated temperatures. Our 68 and 69 series bearings (3mm-5mm bore) are optimized for high-speed stability and low noise, making them ideal for hair dryer motors. They minimize operational sound while ensuring long-lasting performance, even under the heat of continuous use.

3. Electric Shavers

Rotary electric shavers require precision bearings to maintain consistent, vibration-free rotation of cutting heads. Our 60 and 62 series miniature bearings (3mm-6mm bore) deliver stable, low-noise performance even under continuous use. The tight tolerances and smooth rotation of these bearings help reduce skin irritation and improve the overall shaving experience.

4. Beauty & Epilating Devices

Epilators and beauty care appliances rely on precision motion components for smooth, reliable operation. Our 68 and 69 series thin-section bearings (3mm-6mm bore) are ideal for these compact devices, providing the low-friction rotation needed for epilating rollers and oscillating heads. Their durable construction ensures consistent performance, even with repeated daily use.

5. Microwave Ovens 

Modern microwave ovens use miniature bearings in two critical components: cooling fans and rotating turntable motors. Our 60 series bearings (5mm-8mm bore) are ideal for both applications. They are designed to operate reliably under the heat and vibration inside the microwave, ensuring the cooling fan runs quietly and the turntable rotates smoothly for even heating.

6. Blenders & Juicers

High-performance blenders and food processors demand bearings that can withstand high torque, continuous rotation, and varying load conditions. Our 62 and 63 series bearings (8mm-12mm bore) are the preferred choice for blender motors and cutting shafts. With excellent wear resistance and load capacity, they handle the stress of blending, chopping, and pureeing with ease, ensuring consistent performance over years of use.

7. Air Purifiers

Air purifiers rely on quiet, high-performance centrifugal fans to circulate air and filter out pollutants. Our 1-15mm miniature precision bearings, including the 60, 62, and 68 series, are widely used in the fan motors and oscillating louvers of these devices. Engineered for low noise and long service life, our bearings ensure smooth, vibration-free airflow while minimizing operational sound.

8. Household Electric Fans

From table fans to pedestal fans, household cooling appliances use bearings in both the main motor and oscillating mechanisms. Our 608ZZ and 6200ZZ bearings (8mm-10mm bore) are industry standards for fan motors, offering smooth, quiet rotation and extended service life. For the oscillating gears, our 68 series thin-section bearings (5mm-8mm bore) provide the low-friction movement needed for consistent, wobble-free oscillation.

9. Air Conditioners

Air conditioner indoor units use miniature bearings in the blower fan motors and swing louvers. Our 60 and 62 series bearings (6mm-10mm bore) are widely used in these applications, providing stable, low-noise rotation for the fan wheels and louver mechanisms. They are engineered to handle continuous operation, ensuring consistent airflow and temperature control in the home.

10. Vacuum Cleaners

Vacuum cleaners rely on powerful motors and fans to generate suction and airflow, making low-noise, long-life bearings essential. Our 60 and 62 series bearings (5mm-8mm bore) are widely used in vacuum cleaner motors. Their precision manufacturing minimizes friction and noise, while durable construction ensures they maintain performance even with heavy use.

11. Robot Vacuum Cleaners 

Smart robot vacuums require bearings that balance compact design, durability, and low power consumption. Our 60, 68, and 69 series bearings (3mm-8mm bore) are ideal for these devices, used in the drive wheels, side brush motors, and main suction fans. Their smooth, low-friction operation ensures efficient movement and cleaning performance, even on different floor surfaces.
