Introduction
The Centripetal joint bearing is a spherical sliding bearing composed of an inner ring, outer ring, and spherical sliding surface. It allows rotation and oscillation at any angle, suitable for radial loads and small axial loads4. Its self-aligning design compensates for installation errors between the shaft and housing, reducing stress concentration and extending service life
product highlights
High Load Capacity
Made of GCr15 bearing steel with heat treatment (HRC58-64), it can withstand static loads up to 2300kN (e.g., model GEG100ET-2RS)
Self-Aligning Capability
The spherical sliding surface adapts to minor shaft misalignments, with a maximum tilt angle of 17° (e.g., model GEG40ES)
Maintenance-Free Design
Some models (e.g., GE…FW series) use PTFE composite sliding layers, eliminating the need for external lubrication and suitable for harsh environments like dust and moisture
Corrosion Resistance
The inner ring is hard chrome-plated, and the outer ring is phosphated to resist acid and alkali corrosion, with an operating temperature range of -30℃ to +80℃7

Installation & Maintenance
Installation Steps
o Clean the shaft and housing to remove impurities.
o Use heating (80-100℃) or a press for uniform installation, avoiding direct impact
Maintenance Tips
o Regularly check bearing clearance; adjust split outer rings (e.g., GE…HS models) to extend life2.
o Self-lubricating models (e.g., GE…FW) require no lubrication; lubrication-required models need lithium-based grease every 500 hours
FAQ
Q: How to choose the right bearing type for my application?
A: Select based on key parameters:
Load Type: Choose general-purpose models (e.g., GEG…ES) for radial loads; for combined axial loads, ensure the model's axial load capacity (recommended axial load ≤ 30% of radial load).
Swing Requirement: Large swing angles (up to 19°) require GE…C models; precision equipment needs low-tolerance GE…F models.
Environment: Dust/moisture environments need -2RS sealed models (e.g., GEG100ET-2RS); high-temperature scenarios (>80℃) require custom ceramic-coated models.
