Insert bearings are a type of rolling bearing with a special structure. Their outer ring has a spherical outer surface, which can fit with the spherical seat in the bearing housing, providing self-aligning functionality.

I. Common Models

• UC series: The most commonly used housed insert bearings, suitable for general mechanical transmission.
• UEL series: Insert bearings with an eccentric sleeve, facilitating adjusting tightness during installation.
• UK series: Insert bearings with an adapter sleeve, suitable for occasions with larger shaft diameters.

II. Main Functions

• Supporting the rotating shaft: Bears radial loads and small axial loads to ensure stable rotation.
• Self-aligning compensation: Compensates for concentricity errors during installation or slight bending of the shaft.
• Simplifying installation: Eliminates the need for complex shafting positioning structures.

III. Outstanding Advantages

• Excellent self-aligning performance: Adapts to angular deviations (generally ≤2°~3°).
• Convenient installation: Matched with various seat types (vertical, flange) without precisely machined shaft shoulders.
• Strong adaptability: Suitable for harsh environments (low speed, heavy load, dusty conditions).
• Low cost: High cost-performance ratio for occasions with standard precision requirements.
