Types of Slewing Bearings

By Contact Style

Point Contact: Typically uses ball elements for lighter loads and higher rotational speeds.

Line Contact: Utilizes roller elements, ideal for heavy-duty applications with greater load capacity.

By Structural Design

Single-Row Ball Bearing: Compact and cost-effective, suited for moderate load conditions.

Double-Row Ball Bearing: Handles greater axial and radial forces.

Three-Row Roller Bearing: Designed for maximum load-bearing capacity, often used in large machinery.

By Gear Configuration

External Gear: Gear teeth on the outer ring, common in rotating platforms.

Internal Gear: Teeth located on the inner ring for a more compact setup.

Non-Gear (Toothless): Used when external drive sources like gear motors are preferred.
