| title(品名) | 772020 ROLLER BEARING TAPERED, NO.30221 |
| desc(描述) | This design utilizes conical rollers and raceways arranged so that all elements of the roller & raceway cones meet at a common apex on the axis of rotation. The roller is guided by contact between the large end of the roller and a rib on the inner rings. This construction provides high capacity for radial loads & single direction thrust loads. The bearings are usually mounted in pairs with axial adjustment to provide proper running clearance within the bearings. Being separable, the inner and outer rings may be mounted individually. For heavy thrust loads the type 30300D with large contact angle is preferable. Series 30200 |
| cdesc(自动翻译) | 772020 滚针轴承, 锥形, No.30221 这种设计使用锥形滚子和跑道，使得滚子和跑道的锥面都在旋转轴线上相交于一个共同顶点。滚子通过滚子大端与内圈肋骨之间的接触引导。这种结构提供了高径向载荷和单向推力载荷的能力。轴承通常成对安装，并带有轴向调整，以在轴承内部提供适当的运行间隙。由于可分离，内圈和外圈可以单独安装。对于重载推力，建议使用接触角较大的30300D型。系列：30200 |
