[Case Study] Implementation examples in the fields of machine tools, robots, and can manufacturing (Clients: OSG, DMG Mori Seiki)

バリューイノベーションジャパン

<Introduction of Case Studies> ADB has been evaluated and adopted in environments where conventional bearings tend to face challenges, such as vacuum, water, rust, high temperatures, high-speed rotation, and micro-vibrations. Here, we introduce actual delivery cases. ■Delivery Achievements: OSG, DMG Mori Seiki ADB has been adopted for the C-axis of machine tools. One of the critical factors influencing machining capability in machine tools is the high-speed rotation of the spindle. ADB has contributed to achieving a high speed of 30,000 rpm, approximately 2.5 times faster than conventional bearings, due to its low torque characteristics. Additionally, the low torque performance of ADB is also effective in improving the operational efficiency of robots and is utilized in applications aimed at reducing takt time.

Bearing 'ADB' that reduces friction by up to 1/14.
A huge response worldwide! Non-contact between balls without a holder = fundamentally solving the challenges of friction, damage, and lubrication management.

<Structure and Mechanism of ADB> The mechanism of ADB is very simple. There are small "indentations" where the outer ring's balls make contact. In a standard bearing, the balls roll directly beneath the shaft, but in ADB, the indentations on the outer ring cause the balls to roll slightly off to the side from directly underneath. As a result, even though the balls make a complete rotation, the distance they travel is shorter. This causes the balls to slightly decelerate when passing through the indentations and to accelerate again after passing through. Consequently, behind the accelerated balls, the following balls are still decelerating, creating small gaps between the balls. ADB utilizes this principle to naturally separate the balls without the use of retainers.
