In the electronics manufacturing industry, every tiny movement is a matter of product quality. From the placement of precision chips to the stable operation of automated equipment, the performance requirements for core components are at an all-time high. Are you looking for a bearing that offers high precision, high rigidity, compact design, and ensures long-term stable and reliable operation of your equipment?
Our crossed roller bearings were created to address these challenges. We have a deep understanding of the core needs of electronics manufacturers and offer you a complete, optimized bearing solution.
The complexity and variety of application scenarios in the electronics manufacturing industry place severe demands on bearings:
Precision positioning: In semiconductor and PCB manufacturing, automated equipment requires micron-level precision positioning. Traditional bearings have difficulty meeting the requirements in terms of precision and rigidity.
Space constraints: In order to achieve equipment miniaturization and high integration, bearings are required to have extremely small cross-sectional dimensions and compact designs.
High speeds and high loads: Industrial robots and SCARA manipulators require bearings that can withstand both radial and axial loads and maintain high rigidity during rapid handling and assembly.
Long-term Reliability: The equipment needs to carry out 24/7 uninterrupted production, the life and reliability of the bearings have a direct impact on productivity and maintenance costs.
Our crossed roller bearings, with their unique design, are perfectly suited to the demanding standards of the electronics manufacturing industry. Its staggered arrangement of rollers in 90° V-grooves achieves the following core benefits:
1. Extreme High Precision and Rigidity
The special structure of the cross roller bearing enables it to simultaneously withstand multiple loads such as radial, axial and tilting moments without relying on multiple bearing combinations. This design greatly improves overall rigidity and ensures that precision manipulators, SCARA robots and precision rotary tables maintain zero error and high stability during high-speed operation and precision positioning.
2. Compact design saves valuable space
Crossed roller bearings have rollers that are in direct contact with the raceways, realizing extremely small cross-sectional dimensions. This feature makes it ideal for automation equipment, semiconductor manufacturing equipment, and other electronic manufacturing equipment where space is critical.
3. Simplified mounting for improved efficiency
We offer both preloaded and non-preloaded types, which can be selected according to your specific application needs. Standard mounting holes are designed to make the installation process easier and more efficient, shortening the equipment commissioning cycle and speeding up your product launch.
4. Excellent Life and Reliability
We use high quality bearing steel and advanced heat treatment processes to ensure that every crossed roller bearing has excellent wear resistance and fatigue life. This means longer maintenance intervals and less risk of downtime, bringing you tangible productivity gains.
Typical applications: empowering your critical equipment
Our crossed roller bearings have been successfully used in:
Industrial robots and SCARA manipulators: Providing high-precision, high-rigidity rotary support for the joints of robots to ensure their precision in electronic component gripping and placement.
