  1.结构紧凑

通过滚子的直交排列,背对背安装的接触角为45°的单列滚子轴承和球轴承的2个大小的截面面积缩小到了1个大小,有助于节省空间。
2.高 刚 性
右图是转盘旋转部分的截面图。向转盘施加力矩时的作用点距离为L,轴承的容许力矩与作用点距离L成正比。为提高转盘的力矩刚性而增大作用点距离L时,需要使用2个角接触球轴承。同时由于需要留出较大的轴承间距,因此装置体积会变大。而交叉滚子轴承只需使用一个即可增大作用点距离L,不但实现了装置的省空间化,还能提高力矩刚性。
轴承内部的滚动体是使用圆柱滚子的线接触结构,与滚珠型轴承相比,刚性大幅提高。例如与双列角接触球轴承相比,截面尺寸小,刚性提高3 ~ 4倍。
3.可 用 性
通过滚子的直交排列,1个轴承可同时承受来自所有方向的复杂负荷,组装时可以不受负荷方向的影响。
4.品 质
IKO利用长年生产滚子轴承积累的制造及检查经验,可稳定可靠地生产高精度交叉滚子轴承。
5.多 样 性
IKO交叉滚子轴承标准备有丰富齐全的各种产品。对于机床、大型机器人和一般工业设备,外圈和内圈均为一体结构的CRBH型,以及外圈沿轴方向剖分为2部分的CRB和CRBC型是*佳选择。中小型机器人关节部、半导体等的电子电气设备自动装置,适合选用断面尺寸小的薄型CRBS。而对于精密小型装置,截面面积小的超薄型CRBT是*佳选择。
还有用来简化配合轴承座结构、附带安装孔的高刚性CRBF型。
6.灵 活 性
IKO擅长多品种生产,凭借特有的灵活性,也可按照客户的用途,承接交叉滚子轴承的定制生产。包括标准品中没有的形状、尺寸和表面处理等在内,IKO拥有生产各种特殊产品的成功先例,如果标准品不能满足您的要求而需要制作特殊用途的产品,请尽管向IKO咨询。

1. Compact structure
By the orthogonal arrangement of the rollers, the cross-sectional area of ​​the two-row roller bearing and the ball bearing with a contact angle of 45° mounted back-to-back is reduced to one size, which contributes to space saving.
2. High rigidity
The picture on the right is a cross-sectional view of the rotating part of the turntable. When the torque is applied to the turntable, the distance of the action point is L, and the allowable torque of the bearing is proportional to the distance L of the action point. In order to increase the torque of the turntable and increase the distance L of the action point, two angular contact ball bearings are required. At the same time, due to the need to leave a large bearing spacing, the device volume will become larger. The cross roller bearing can increase the distance L of the action point by using only one, which not only realizes the space saving of the device, but also improves the torque rigidity.
The rolling element inside the bearing is a line contact structure using a cylindrical roller, and the rigidity is greatly improved as compared with the ball type bearing. For example, compared with double row angular contact ball bearings, the cross-sectional size is small and the rigidity is increased by 3 to 4 times.
3. Availability
By the orthogonal arrangement of the rollers, one bearing can withstand complex loads from all directions at the same time, and can be assembled without being affected by the load direction.
4. Quality
IKO utilizes years of experience in manufacturing and inspection of roller bearings to produce high-precision cross-roller bearings in a stable and reliable manner.
5. Variety
IKO cross roller bearing standards are available in a wide range of products. For machine tools, large robots and general industrial equipment, the CRBH type with the outer ring and inner ring are integrated, and the CRB and CRBC type with the outer ring divided into two parts along the axial direction are the best choice. Small and medium-sized robots, joints, semiconductors, and other electronic and electrical equipment automatic devices, suitable for thin CRBS with small cross-section. For precision small devices, ultra-thin CRBT with a small cross-sectional area is the best choice.
There is also a high-rigidity CRBF type that simplifies the construction of the housing and the mounting holes.
6. Spirituality
IKO specializes in multi-variety production, with its unique flexibility, it can also be customized for cross-roller bearings according to customer's application. Including the shape, size and surface treatment that are not included in the standard, IKO has a successful precedent for producing various special products. If the standard does not meet your requirements and you need to make a special-purpose product, please contact IKO.
