What's the Performance Features of CRBTF105A Crossed Roller Bearing?
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.
What's the Applications of the CRBTF105A Crossed Roller Bearing?
The CRBTF105A cross roller bearing, with its high precision, high load-carrying capacity, and compact
design, is widely used in the following fields:
1. Industrial Robots:
Components requiring high-precision rotation, such as robotic arm
joints and RV reducers.
2. Precision Turntables:
Applications requiring low friction and high stability, such as
machining centers in machine tools and turntables for optical
instruments.
3. Small-Sized Equipment:
Examples include PTZ (pan-tilt-zoom) mechanisms for surveillance
cameras and micro transmission systems in automated equipment.
CRB Series (Integrated Inner/Outer Ring Type) Crossed Roller
Bearing
I. Structural Characteristics
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.
II. Performance Advantages
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).
