使用环境:极限转速比较高,旋转精度高,耐高温消毒,耐腐蚀,静音效果好。
Use environment:High limit speed, high rotation accuracy, high temperature disinfection resistance, corrosion resistance, good silence effect.
优缺点:极限转速比较高;摩擦力矩比较小; 可同时承受径向和轴向载荷; 同样的外型尺寸比深沟球轴承动、静载荷容量大; 旋转精度高、噪音小。使用寿命非常高。
Merits and faults :Limit speed is relatively high; friction moment is relatively small; can bear both radial and axial loads; the same size than deep groove ball bearings dynamic and static load capacity; high rotation accuracy, low noise. The service life is very high.
