⚙️Product description:
The 698ZZ is made of bearing steel (such as GCr15), with a rated dynamic load capacity of approximately 1.46 KN and a rated static load capacity of about 0.465 KN. Under grease lubrication, its maximum speed can exceed 15,000 r/min (the exact value may vary slightly due to installation methods and operating temperatures). It comes with a standard precision grade of P0, which meets the requirements of most general applications. Higher precision versions such as P6 (ABEC 3) and P5 (ABEC 5) are also available.

Easy protection and lubrication: The double-sided metal dust-proof cover can firmly prevent dust, fine debris and other impurities from entering the bearing interior, avoiding wear on the raceways and steel balls, and also reducing the loss of pre-filled lubricating grease during factory production, achieving no initial lubrication and extending the service life of the bearing.
Suitable for high-speed operation: The deep groove ball structure design combined with high-quality bearing steel material significantly reduces friction during operation. It can meet the high-speed requirements of small motors and other equipment, and the noise during operation is relatively low, which is suitable for scenarios that require smooth operation.
Flexibility in adaptability: In addition to the regular basic model, different precision grades and materials can be selected according to requirements, which can not only meet the basic transmission needs of ordinary small equipment, but also adapt to the higher requirements for size tolerance and rotational accuracy of some precision equipment.
