Robotics and Automation — Precision Slewing Bearings
I. Industrial Automation requires precision bearing
Industrial automation equipment is crucial for improving production efficiency and stability. Automated machinery, robotic systems, packaging lines, and testing equipment require high-precision, long-life, and low-maintenance rotating components. Slewing bearings, with high load capacity, smooth rotation, and compact structure, have become indispensable in industrial automation.
II. What are slewing bearings? — The "rotational core" of industrial automation
Slewing bearings are specialized bearings capable of supporting axial loads, radial loads, and overturning moments simultaneously. They enable large-diameter, low-speed, high-load rotation and are widely used in equipment requiring precise positioning and continuous rotation. In industrial automation, slewing bearings bridge control systems and actuators, ensuring precision, stability, and responsiveness under high-speed and high-frequency dynamic operation.
Types of Slewing Bearings Used in Industrial Automation
| Slewing Bearing Type | Main Features | Load Capacity | Precision Class | Typical Applications |
|---|---|---|---|---|
| Single-row Four-point Contact Ball | Lightweight structure, flexible rotation | Medium | Medium | Packaging, testing platforms |
| Crossed Roller Slewing Bearing | High rigidity, high precision | High | High | Robots, rotary tables |
| Double-row Ball Slewing Bearing | Good stability, strong load-bearing | High | Medium | Assembly, sorting systems |
| Three-row Roller Slewing Bearing | Ultra-high load-bearing, impact-resistant | Extremely High | Medium | Heavy-duty automation equipment |
| Thin-section Slewing Bearing | Lightweight, fast response | Medium | High | Small automation equipment |
| Gear Ring | Engageable with motor, easy to control | High | High | Automatic turntables |
| Non-gear Ring | Low noise, smooth operation | Medium | High | Medical and electronic equipment |
