ブレイブラ Product Lineup

The ADB allows balls rotating without a retainer to autonomously disperse, achieving a non-contact state between the balls. As a result, most issues related to the retainer are resolved, leading to improved energy-efficient, high-speed rotation performance with extremely low friction, load-bearing capacity, maintenance-free operation without oil, and increased design flexibility due to the elimination of retainer space, making it possible to adopt smaller and lighter bearings.

The "ADBS7902VV" is an angular ADB bearing in size 7902 (inner diameter 15mm × outer diameter 28mm × width 7mm). It is filled with 15 standard stainless steel balls, and both the inner and outer rings are made of stainless steel. It features a non-contact rubber seal, and the black sealing surface has a larger gap due to the shape of the inner ring. The autonomous distributed rolling bearing (ADB) completely eliminates the retainer, which was a common feature in bearings, allowing for non-contact rotation between the balls without a retainer, enabling a larger number of balls to be filled. 【Features】 ■ Filled with 15 standard stainless steel 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.

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.
