CRBTF

Overview of CRBTF Series Crossed Roller Bearings

Design Features

The CRBTF Series is a type of super slim crossed roller bearing with an ultra-thin 5 mm bearing width. Unlike the standard slim types, CRBTF bearings are equipped with pre-machined mounting holes on both the inner and outer rings, allowing for direct installation to equipment surfaces. This eliminates the need for complex housing structures and reduces overall system bulk.

Crossed Roller Structure

Cylindrical rollers are arranged orthogonally in a 90° V-groove and separated by precision-machined spacers. This arrangement enables the bearing to withstand radial, axial, and moment loads simultaneously, ensuring smooth, stable, and accurate rotational performance in limited-space environments.

Technical Specifications

• Design: Ultra-thin with mounting holes on both rings
• Inner Diameter (ID): 10 mm – 40 mm
• Outer Diameter (OD): 43 mm – 73 mm
• Bearing Width: 5 mm
• Feature: Compact, lightweight, and easy to mount

Key Advantages

• Ultra-slim profile: Only 5 mm thick, ideal for equipment miniaturization
• Pre-machined mounting holes: Allows direct mounting without housings or clamp plates
• High rigidity: Suitable for high-precision motion systems
• Multi-directional load support: Handles radial, axial, and moment loads with stability
• Low friction and smooth rotation: Thanks to the separator-equipped roller design

Application Scenarios

The CRBTF Series bearings are particularly well-suited for industries and devices that demand compact construction and high performance:

• Robotics: Enables precise joint motion in compact robotic arms
• Medical devices: Used in surgical robots, MRI systems, and diagnostic imaging equipment
• Semiconductor equipment: Provides accuracy and stability for wafer handling and alignment
• Optical and measurement instruments: Ensures stable rotation in cameras, telescopes, and gauges
• Aerospace and defense: Ideal for satellite positioning systems and precision targeting devices

Conclusion

Thanks to its ultra-slim design, integrated mounting holes, and excellent rigidity, the CRBTF Series Crossed Roller Bearing is a practical choice for high-precision applications where both compactness and ease of assembly are crucial. Its ability to support complex loads while simplifying installation makes it an ideal solution across various high-tech industries.
