At APO-GEE, we redefine ball bearing analysis by moving beyond traditional Newtonian methods, which focus on forces and moments. 𝗠𝗼𝘀𝘁 𝗲𝘅𝗶𝘀𝘁𝗶𝗻𝗴 𝘁𝗼𝗼𝗹𝘀 𝘂𝘀𝗲 𝗮 𝗡𝗲𝘄𝘁𝗼𝗻𝗶𝗮𝗻 𝗳𝗼𝗿𝗺𝗮𝗹𝗶𝘀𝗺 based on the equilibrium of forces and moments. However, no calculation or modeling method can accurately approximate the effective behavior of a ball bearing through Newtonian formalism alone. For this reason, all methods and conventional Newtonian-dynamics-based software currently used to model ball bearing behavior have shown 𝗹𝗶𝗺𝗶𝘁𝗮𝘁𝗶𝗼𝗻𝘀 𝗼𝗿 𝗶𝗻𝗰𝗼𝗺𝗽𝗹𝗲𝘁𝗲𝗻𝗲𝘀. They cannot achieve true equilibrium of the bearing because they rely on simplifying assumptions about ball kinematics. The core of APO-GEE's approach is a 𝗴𝗿𝗼𝘂𝗻𝗱𝗯𝗿𝗲𝗮𝗸𝗶𝗻𝗴 𝗲𝗾𝘂𝗶𝗹𝗶𝗯𝗿𝗶𝘂𝗺 𝗰𝗿𝗶𝘁𝗲𝗿𝗶𝗼𝗻 𝗯𝗮𝘀𝗲𝗱 𝗼𝗻 𝗽𝗼𝘄𝗲𝗿. In fact, meeting this criterion is equivalent to satisfying Newton's laws of motion. However, unlike the Newtonian approach, APO-GEE’s methodology enables a 𝗰𝗼𝗺𝗽𝗹𝗲𝘁𝗲 𝗰𝗼𝗺𝗽𝘂𝘁𝗮𝘁𝗶𝗼𝗻 𝗼𝗳 𝗯𝗮𝗹𝗹 𝗸𝗶𝗻𝗲𝗺𝗮𝘁𝗶𝗰𝘀, achieving the true equilibrium of the ball bearing—without approximation—regardless of the operating conditions (loads, misalignment, speed, etc.).

As a direct consequence, the need for higher-performing bearings in cooling fan motors has also grown, with a strong focus on reducing vibration and noise. One way to achieve this is by addressing cage instability—sometimes referred to as cage whirl—a phenomenon that can occur in the bearings used in cooling fan motors, generating significant noise. At APO-GEE, we've developed an innovative solution: the Butterfly Cage. This technology prevents any cage instability, effectively reducing noise and ensuring a smoother operation. Tested and proven in aerospace applications and precision machinery, APO-GEE’s Butterfly Cage can now bring a concrete answer to some of the challenges faced by the ICT industry.

Based on more than 12 years of intensive and focused research, APO-GEE has developed strong expertise in application engineering and the creation of innovative ball bearing solutions. People often ask us what drives our success. The answer lies in our unique approach. While conventional ball bearing models often rely on Newtonian mechanics and force equilibrium, they simplify key aspects of ball kinematics. This can leave gaps in accurate modeling and understanding. APO-GEE has redefined this landscape with an innovative method that introduces a power-based equilibrium criterion. Our approach respects Newton’s laws but goes further, allowing us to achieve precise kinematic computations for true bearing equilibrium—without approximations. This cutting-edge methodology has enabled breakthrough innovations like our Butterfly cage and Cobweb bearing, both made possible through our specialized computational suite, ROSE.

𝗪𝗵𝗮𝘁 𝘄𝗼𝗿𝗸𝘀 𝗳𝗼𝗿 𝘀𝗽𝗮𝗰𝗲 𝗯𝗲𝗮𝗿𝗶𝗻𝗴𝘀 𝗰𝗮𝗻 𝘄𝗼𝗿𝗸 𝗳𝗼𝗿 𝗲𝘃𝗲𝗿𝘆𝘁𝗵𝗶𝗻𝗴—𝗶𝗻𝗰𝗹𝘂𝗱𝗶𝗻𝗴 𝗺𝗮𝗰𝗵𝗶𝗻𝗲 𝘁𝗼𝗼𝗹𝘀 Bearing cages in spindles can rattle during rotation due to « cage instability », causing vibrations and reduced performance. This impacts both bearing efficiency and machine tool accuracy. Cage instability remains unpredictable. Even in space missions, despite extensive testing, instabilities can still occur, either at the start or even years later. Why? Even well-designed cages have a narrow "operational window" for stability. A small change in geometry or working conditions can turn a good cage into a bad one. APO-GEE understands cage instability mechanisms and developed the Butterfly cage. It expands the operational window, ensuring stable performance. This innovation benefits not only space but now also machine tool spindles. Learn more at www.apo-gee.tech.

𝗔 𝗰𝗮𝗴𝗲 𝗶𝘀𝘀𝘂𝗲 𝗶𝗻 𝗮 𝗯𝗲𝗮𝗿𝗶𝗻𝗴 𝗰𝗮𝗻 𝗯𝗲 𝗯𝗼𝘁𝗵 𝗮 𝗰𝗮𝘂𝘀𝗲 𝗮𝗻𝗱 𝗮 𝗰𝗼𝗻𝘀𝗲𝗾𝘂𝗲𝗻𝗰𝗲 The phenomenon of cage instability can lead to noise, vibrations, and sometimes cage breakage. This can occur in space applications (RWA, gyros, turbopumps), as well as in other industrial applications such as machine tools-spindles or turbomolecular pumps, for example. In this case, the cage is clearly the 𝗖𝗔𝗨𝗦𝗘 of the defect within the bearing. The good news is that a very concrete solution exists to solve the problem: the 𝘽𝒖𝙩𝒕𝙚𝒓𝙛𝒍𝙮 𝙘𝒂𝙜𝒆 (see https://lnkd.in/eUSChWbW). However, a cage breakage can also be a 𝗖𝗢𝗡𝗦𝗘𝗤𝗨𝗘𝗡𝗖𝗘 of another phenomenon: Ball Speed Variation (ball advance at non-constant speed in the bearing). This deleterious phenomenon often occurs when bearings support a combined load and rotate at high or very high speeds. The attached video explains the profound nature of the phenomenon. The good news is that here too, a concrete solution exists: the 𝘾𝙤𝙗𝙬𝙚𝙗 𝘽𝙚𝙖𝙧𝙞𝙣𝙜 (see https://lnkd.in/eSXDh3pb).
