1 产品特征:
带座外球面球轴承是一个双面密封且外圈具有球形外截面的宽内圈深沟球轴承。
2 XLB提供如下几种不同型式的密封结构:
防尘盖与橡胶密封圈组合密封:防尘盖固定在内圈上与内圈一起旋转,橡胶密封圈固定在外圈上,密封胶唇与内圈形成标准扭矩接触密封,这种密封能有效地防止外部泥土、灰尘、水气等异物进入轴承内部,同时能阻止轴承内部的润滑脂外漏,使轴承在恶劣的工作环境下也能保持完美的工作性能。如图1。?
三唇密封形式,金属防尘盖上带有三重细长密封胶唇的严格密封,具有较大的按触密封扭矩。适用于环境特别恶劣的农业机械上。如图2。
防尘盖粘橡胶的密封形式:防尘盖与长密封胶的双重密封作用,胶唇与内圈形式以标准扭矩接触密封,能有效地阻止外部泥土、灰尘、水气等异物进入轴承内部,同时也阻止轴承内部的润滑脂外漏。如图3。
3.应用场合
外球面轴承广泛应用于农业机械、建筑机械、纺织机械、食品加工机械及输送带系统等领域。
