ADB that keeps the balls non-contact without a retainer! Providing a dramatic solution that doesn't rely on lubrication.
The "ADBS7902CVV" is an angular ADB bearing with a size of 7902 (inner diameter 15mm × outer diameter 28mm × width 7mm). The autonomous distributed rolling bearing (ADB) completely eliminates the retainer, which has been a common feature in bearings. It achieves low friction and ultra-high-speed rotation, load-bearing performance, lubrication-free operation, and long lifespan at levels that are difficult to reach with conventional bearings. It is filled with 15 Si3N4 ceramic balls, and both the inner and outer rings are made of stainless steel. It employs a non-contact rubber seal, and the black seal surface has a larger gap due to the shape of the inner ring. 【Features】 ■ Filled with 15 Si3N4 ceramic balls ■ Inner and outer rings made of stainless steel ■ Non-contact rubber seal *For more details, please download the PDF or feel free to contact us.
