超小型交叉滚子轴承有助于缩小自动化设备设计

Ultra-Small Crossed Roller Bearings Help Shrink Automated Equipment Designs

当您需要将紧凑型轴承整合到空间受限的自动化机器设计中时，您可能认为必须牺牲精度。毕竟，如果您有复杂的或高速的旋转负载，自然会寻找结构坚固、能够提供良好精度和刚性的大型轴承。如果您受到空间有限的自动化或机器人机器设计的挑战，则需要额外考虑交叉滚子轴承。交叉滚子轴承是先进的产品，非常适合空间受限的自动化机器设计。而且，IKO International 的新型交叉滚子轴承可以提供精确、可重复的运动，并适合您设备的狭小空间。

两种理想属性的组合

交叉滚子轴承设计为在内圈和外圈之间以直角交替交叉的滚子。这种布置产生了更大的接触面，使轴承能够同时处理来自任何方向的重载或复杂载荷。由于这种正交的滚子阵列，交叉滚子轴承可以帮助减小许多自动化设备设计的尺寸。

IKO International 的新型 CRBT105A 具有超小尺寸：10 毫米内径、21 毫米外径和 5 毫米窄宽度。它占后置式 45 度接触角单列滚子或滚珠轴承的一半截面积。

尽管尺寸紧凑，但 CRBT105A 的刚度是双列角接触球型轴承的四倍。这种小尺寸和高刚性的结合使得 CRBT105A 适用于带有关节臂的机器人，并且它也可以用于紧凑型监控摄像头，因为它可以处理各个方向的复杂负载。其他功能和规格包括：

圆柱滚子之间的分离器可提供平稳的旋转。

额定动载荷为 1,120N，额定静载荷为 811N。

高速旋转时摩擦系数小。

轻量化设计。

领先于自动化设备不断缩小的尺寸要求

具有高速或旋转、复杂负载的自动化设备的设计人员可以通过紧凑型交叉滚子轴承获得高刚性和精度。IKO 的 CRBT105A 交叉滚子轴承提供比双列角接触球型轴承中通常发现的更大的刚度和平滑的旋转，同时帮助设计人员保持领先于不断缩小的尺寸要求。

When you need to incorporate a compact bearing into a space-constrained automated machine design, you may think you have to sacrifice precision. After all, if you have a complex or high-speed rotating load, it’s natural to look for a large bearing with solid construction that can provide good accuracy and rigidity. If you’re challenged by an automated or robotic machine design with limited space, it pays to give crossed roller bearings extra consideration. Crossed roller bearings are advanced products that are ideal for space-constrained automated machine designs. And, new crossed roller bearings from IKO International can deliver precise, repeatable motion and fit within the tight confines of your equipment.

A Combination of Two Desirable Attributes

Crossed roller bearings are designed with the rollers alternately crossed at right angles to each other between inner and outer rings. This arrangement creates a greater contact surface to allow the bearing to handle heavy or complex loads from any direction simultaneously. Thanks to this orthogonal array of rollers, crossed roller bearings can help reduce the size of many automated equipment designs.

IKO International’s new CRBT105A offers ultra-small dimensions: a 10 millimeter bore diameter, 21 millimeter outside diameter and a narrow width of 5 millimeters. It occupies half the sectional area of rear-mounted, 45-degree contact angle single-row roller or ball-type bearings.

Despite its compact size, the CRBT105A offers rigidity up to four times greater than double-row angular contact ball-type bearings. This combination of small size and high rigidity makes the CRBT105A suitable for robots with articulating arms, and it also can find use in compact surveillance cameras because it can handle complex loads in all directions. Additional features and specifications include:

Separators between cylindrical rollers to provide smooth rotation.

Dynamic load rating of 1,120N and static load rating of 811N.

Small coefficient of friction for high-speed rotation.

Lightweight design.

Stay Ahead of Automated Equipment’s Always-Reducing Size Requirements

Designers of automated equipment with high-speed or rotating, complex loads can obtain high rigidity and precision with a compact crossed roller bearing. IKO’s CRBT105A crossed roller bearing delivers greater rigidity than typically found in double-row angular contact ball-type bearings plus smooth rotation while helping designers stay ahead of ever-shrinking size requirements.
