CRBTF105A 10mm Bore 5mm Width Crossed Roller Bearing High Rigidity Compact Robot Joint Bearing

The CRBTF105A bearing is designed for high-precision rotational motion, featuring crossed cylindrical rollers arranged at right angles to provide exceptional rigidity and load-bearing capacity.

• Outer Diameter: 43 mm
• Bore Diameter: 10 mm
• Width: 5 mm
• Structure: Integrated compact design supporting radial, axial, and moment loads in any direction
• Installation: Simplified by eliminating the need for a mounting flange

The CRBTF105A bearing excels in applications requiring high performance and reliability, offering superior stiffness and load capacity while simplifying installation.

CRBTF105A is a thin-walled cross roller bearing, primarily used in industrial scenarios that demand high precision and lightweight design.

• Lightweight Design: Compared to traditional models, its weight is reduced by approximately 62%, with a cross-section height of only 5 mm, making it suitable for compact space applications
• High Rigidity: The cross-roller structure can withstand axial, radial, and overturning moment loads, offering 3-4 times higher rigidity than traditional bearings
• High Precision: The precision grade can reach P2/P4/P5 levels, making it ideal for precision equipment such as robotic joints, medical instruments, and more

The CRBTF105A cross roller bearing, with its high precision, high load-carrying capacity, and compact design, is widely used in the following fields:

• Industrial Robots: Components requiring high-precision rotation, such as robotic arm joints and RV reducers
• Precision Turntables: Applications requiring low friction and high stability, such as machining centers in machine tools and turntables for optical instruments
• Small-Sized Equipment: Examples include PTZ (pan-tilt-zoom) mechanisms for surveillance cameras and micro transmission systems in automated equipment

Split Outer Ring and Integral Inner Ring Design

• The outer ring is divided into two parts, while the inner ring is a single-piece structure, facilitating installation and clearance adjustment
• Features an equal cross-section thin-walled design, with both inner and outer ring thickness minimized to suit compact space applications

Rolling Element Arrangement

• Cylindrical rollers are arranged in a 90° cross pattern, with spacers maintaining their spacing to prevent friction and locking phenomena

• High Load-Carrying Capacity: Capable of simultaneously withstanding radial, axial loads, and overturning moments, making it suitable for heavy-load applications (e.g., cranes, construction machinery)
• High Rigidity and Precision: Offers 3-4 times higher rigidity than traditional bearings, with rotational accuracy reaching P4 and P2 levels, ideal for precision equipment (e.g., CNC machine tools, medical instruments)
• Lightweight and Compactness: Extremely thin walls and reduced weight make it suitable for weight-sensitive applications such as robotic joints and manipulators
• High-Speed Performance: Low-friction design supports high-speed rotation (e.g., DD motors, high-speed indexing tables)
