Designed for high-precision applications, the 7012-7019 series angular contact ball bearings feature paired installation for axial rigidity, heavy radial/axial loads, and high-speed operations. Common in industrial machinery, robotics, and automotive systems.
Modelo | Diâmetro do furo (mm) | Diâmetro exterior (mm) | Largura (mm) | Carga dinâmica (kN) | Carga estática (kN) | Velocidade máxima (rpm) |
---|---|---|---|---|---|---|
7012 | 60 | 95 | 18 | 24.5 | 16.2 | 10,000 |
7013 | 65 | 100 | 18 | 26.8 | 18.0 | 9,500 |
Nota. Custom preload levels, lubrication, and materials (e.g., ceramic) are available.
Problema. Vibration in a 15,000 rpm spindle caused premature failure.
Solução. Upgraded to 7016 bearings with adjusted preload, reducing downtime by 40%.
Desafio. Axial play in high-torque EV drivetrains.
Resultado. 7019 duplex bearings increased service life by 60% under 300 N·m loads.
Aplicação. High-speed EV charging pump bearings (7014 series).
Resultado. 18-month operation without maintenance at 8,000 rpm.
Requisito. ±2μm precision in surgical robot arms.
Desempenho. 7017 bearings achieved 98% accuracy over 10M cycles.
