Product Features
- Load Capacity: Simultaneously withstands large radial loads and unidirectional axial loads (combined loads)
- Adjustment Angle: Typically 1°~4.5°, depending on model size (larger sizes have smaller angles)
- Operating Conditions: Suitable for low-speed swing (<600 swing/min) and reciprocating motion, not recommended for high-speed rotation
- Lubrication Method: Requires regular addition of lubricating grease through oil groove and oil hole; recommended lithium-based or extreme pressure lubricating grease
- Temperature Range: Standard range from -30°C to +120°C, up to 150°C under extreme conditions
Important Note: This bearing type cannot withstand bidirectional axial loads. For bidirectional loading requirements, install in pairs in reverse orientation.
Application Information
Common Applications
- Construction Machinery: Excavator arm connections, loader steering knuckles, crane pivot points
- Automotive Systems: Balance bridge suspension, steering rod joints, transmission shaft universal joints
- Industrial Equipment: Welding robot joints, rotary table supports, hydraulic cylinder hinge points
- Mining & Metallurgy: Crusher swing arms, conveyor hinges, steel rolling equipment connection parts
Installation Guidelines
Align Installation Direction
Ensure the lubrication groove on the outer ring is oriented toward a position convenient for later maintenance (upward or lateral) to facilitate lubricating grease addition.
Use Specialized Tools for Press Fit
Apply force smoothly and vertically to avoid inner ring deformation or spherical surface damage from eccentric load.
Control pressing speed at 0.1-0.3 mm/s to prevent impact-induced coating peeling or retaining frame damage.
Precautions for Paired Installation
For equipment requiring bidirectional axial force resistance, install two GAC.S bearings back-to-back or face-to-face in pairs with consistent preload force to prevent eccentric wear.
Purchasing Guide
- Model Selection: Select based on load requirements with priority given to rated dynamic load CC, ensuring C > 1.2 * Peq (equivalent load)
- Safety Factor: Increase to 1.5 times or more for high-impact working conditions
- Lubrication Maintenance: In dusty environments, add lubricating grease every 500 hours
- Extended Maintenance: Models with sealing rings (such as -2RS) can extend lubrication intervals
