Design Principles

Crossed roller bearings are a type of specially designed roller bearing characterized by rollers arranged at 90 degrees to each other. This design allows for the simultaneous support of high radial, axial, and moment loads. The arrangement of the rollers in an alternating pattern significantly enhances the bearing's load capacity and precision.

Performance Features

The performance features of crossed roller bearings include:

• High load capacity: The crossed arrangement of rollers provides greater stability and load capacity than traditional bearings.
• High precision: These bearings maintain high precision and rigidity, making them suitable for precision applications.
• Compact design: The crossed arrangement allows for a large load capacity in a small space.
• Low frictional torque: Crossed roller bearings typically have low frictional torque, which helps to improve mechanical efficiency and reduce heat generation.

Application Scenarios

Crossed roller bearings are suitable for the following scenarios:

• Robotics: In joints and rotating parts where high load capacity and precision control are required.
• Rotary tables and indexers: In machine tools, where precision positioning and support for composite loads are needed.
• Medical equipment: Such as rotating parts in CT scanners and MRI machines, which require high precision and reliability.
• Aerospace and aviation: In positioning mechanisms for satellite solar arrays and in aviation control systems.
• Industrial automation: In automated equipment requiring precise positioning and motion.
• Precision measurement equipment: In measuring instruments and devices that need high-precision support and stability.
