CRBT Crossed Roller Bearings

Q: How do CRBT Crossed Roller Bearings differ from traditional thin section bearings?

Traditional thin section bearings are typically ball bearings, primarily designed to handle radial loads. While they also feature a lightweight design, their performance is limited when simultaneously bearing radial, axial, and moment loads. In contrast, CRBT Crossed Roller Bearings uniquely arrange cylindrical rollers in a 90-degree cross pattern, allowing them to simultaneously withstand all three types of loads within a single bearing. This design provides higher rigidity and load-bearing capacity while maintaining the thin section advantage, making them particularly suitable for robot joints and rotating platforms that require high precision and high rigidity.

Q: Is the installation of CRBT Crossed Roller Bearings complex?

Relatively, the installation of CRBT Crossed Roller Bearings is very convenient. The inner and outer rings of this series are integrated, which greatly simplifies the installation process. Unlike bearings that require additional fixing flanges or supporting housings, CRBT bearings are easier to mount due to their integrated design. Furthermore, their one-piece structure reduces the impact of installation errors on bearing performance, thereby ensuring stable rotational accuracy and torque.

Q: What types of applications are most suitable for CRBT Crossed Roller Bearings?

CRBT Crossed Roller Bearings are highly suitable for applications requiring high precision motion, high rigidity, and compactness. Key applications include the swivel joints of compact hand robots where accurate positioning is crucial. They are also ideal for surveillance cameras that demand stable, continuous 24-hour operation due to their ability to receive complex loads and maintain high rotational accuracy. Their lightweight nature also benefits equipment where power saving is a consideration.

Q: Can CRBT Crossed Roller Bearings effectively handle both radial and axial loads simultaneously?

Yes, one of the significant advantages of all crossed roller bearings, including the CRBT series, is their ability to effectively handle simultaneous radial, axial, and overturning moment loads. This is achieved through their unique internal design where cylindrical rollers are arranged in a crossed configuration at 90-degree angles. This allows a single CRBT bearing to provide the equivalent of two separate traditional bearings, offering robust support in multiple directions within a very compact type footprint.

CRBT Crossed Roller Bearings are a unique type of super-slim bearing, featuring a cross-sectional height of just 5.5mm and a width of 5mm. This extremely compact design allows them to excel in space-constrained applications. Unlike conventional bearings, the CRBT series ensures smooth rotation by incorporating separators between the rollers, while also providing the high rigidity and high precision required for many robot bearings and other high precision bearings applications. Their compact, lightweight, and smooth operation properties contribute to the downsizing of machinery and saving driving power, making them a specialized and precise member of the crossed roller bearings family.

Ultra-Slim Design for Space-Saving Applications

CRBT Crossed Roller Bearings are specially developed for next-generation precision machinery. With a sectional height of just 5.5mm and a width of 5mm, they are among the thinnest crossed roller bearings available. Their super compact structure allows engineers and designers to significantly reduce the overall size and weight of their equipment without compromising performance. This is particularly important in modern applications such as robotic joints, small-scale rotary mechanisms, and surveillance systems, where internal space is extremely limited.

Despite their minimal profile, CRBT Crossed Roller Bearings offer excellent load-carrying capacity, enabling them to handle radial, axial, and moment loads simultaneously. The orthogonally arranged cylindrical rollers allow for stable rotation and help maintain the integrity of the mechanism even under variable loads. These features make them a preferred choice for robot bearings and thin section bearings, where balance between precision and compactness is essential.

Smooth Motion with Integrated Spacers for Stable Operation

One of the most important features of CRBT Crossed Roller Bearings is the integration of spacers (separators) between each cylindrical roller. These spacers are designed to prevent direct contact between rollers, thereby reducing internal friction, minimizing wear, and ensuring consistent smooth rotation. This structure plays a key role in systems that demand continuous, quiet, and reliable operation, such as surveillance camera gimbals, automated inspection heads, and robot wrists that execute repetitive fine motions.

In applications where 24/7 operation is required, even minor vibration or torque fluctuation can affect system accuracy. Thanks to the spacer-enhanced structure, CRBT bearings maintain low torque and minimal vibration, which enhances the overall control and precision of the machine. They also contribute to energy efficiency by reducing drive resistance, making them ideal for battery-powered robots, lightweight actuators, and portable medical systems.

Diverse Applications: From Robotics to Surveillance Equipment

In the joints of compact robots, each joint needs to withstand loads from multiple directions within a limited space while maintaining high precision and rigidity. CRBT bearings are specifically designed for this purpose. They can simultaneously bear radial, axial, and moment loads within a single unit, effectively simplifying the design and reducing the required installation space.

In addition to the robotics field, CRBT bearings are also widely used in other equipment that requires high precision and a compact design. For example, in compact surveillance cameras, CRBT bearings can support continuous 24-hour rotational motion, withstand complex loads from different directions, and ensure the accuracy of the camera’s positioning. The thin section bearings characteristic also makes them an ideal choice for precision fields such as medical equipment, measuring instruments, and semiconductor manufacturing equipment.
