BNR/BER系列超高速密封角接触球轴承

BNR/BER系列超高速密封角接触球轴承外部加装防尘密封、密封圈等装置，防止外部灰尘、污垢等污染物混入轴承内部，有效降低污染物对轴承性影响，延长轴承使用寿命，降低维护成本。此系列为BNR/BER29、20密封系列，接触角有18° （BNR）、25° （BER）2种，球材质有钢球（S）、超长寿命轴承滚动体（E）、陶瓷球（H、X）3种，保持架有外圈引导酚醛树脂保持架（T）、外圈引导PPS树脂保持架（TSR）、滚动体引导聚酰胺树脂保持架（TYN）4种。由于密封结构设计，轴承内部润滑剂能长期保持清洁，减少摩擦磨损，提高旋转精度，这种设计在高精度机械设备中应用广泛。

BNR/BER系列超高速密封角接触球轴承的采用非接触式密封结构不会明显影响轴承高速性能，同时也能在高速旋转下保持稳定运行状态，这个特点使得它在高速电机、涡轮增压器等设备中得到广泛使用。此系列采用了预润滑设计，安装时不要额外润滑，一定程度上简化了安装过程，提升了效率。密封角接触球轴承减少润滑剂泄漏的可能性，大幅度降低了维护成本，支持长时间在设备中使用，减少更换轴承频率和成本。密封轴承具有优异的耐久性能，BNR/BER系列超高速密封角接触球轴承通过密封圈和保持架之间间隙、密封圈迷宫结构的最优化设计，防止润滑脂泄漏。29、20系列的轴承经过特殊设计，现已提高润滑脂填充量、抑制温度上升的同时，实现润滑脂长寿命同时能够防止外部异物侵入。注意密封轴承填充了高等级、低粘度的润滑脂，约为其自由空间的15%。密封轴承在正常的工况下无需再润滑，已填充润滑脂的轴承和带密封圈轴承安装时无需清洗，但要用清洁的布擦去外部防锈油后进行安装。
