直孔带密封型
直孔型双面带密封的调心球轴承，是GKRW为需防尘、防油及长期免维护工况提供的优质解决方案。该密封轴承主要包括2200和2300两大系列，内径尺寸覆盖10mm至70mm，适配多数中小型设备安装需求。两侧均装有接触式密封圈，密封件采用带钢骨架的丁腈橡胶（NBR）制成，具备优异的耐油性和耐磨性，能有效阻止外部粉尘、水分和油污侵入轴承内部，同时抑制润滑脂外泄，型号后缀为2RS。由于出厂前已预填高品质润滑脂，该系列轴承可实现终生润滑，在正常使用条件下几乎无需额外维护，显著降低设备保养频率和人工成本。但需注意，与开式调心球轴承相比，密封结构对轴承的内部游隙和调心性能有一定影响，因此其允许的不对中角度有所减小，安装时应尽量保证轴与轴承座的对中精度，以发挥轴承的最佳性能。如需更高调心要求或特殊工况，建议联系GKRW工程师获取选型指导。
