External Gear Slewing Bearing

The HS Ball Slewing Bearing category encompasses a variety of bearings designed for smooth rotation and exceptional load capacity. You'll find the option for External Gear Slewing Bearing within this category. These bearings combine the precise movement of ball bearings with the integration of teeth on the outer ring. Design and Construction  External gear HS ball slewing bearings incorporate a toothed gear ring on the inner diameter of the bearing. This gear ring meshes with a pinion or other driving mechanism, allowing direct rotation control. The bearing is comprised of a high-strength steel inner and outer raceway, with multiple rows of precision balls between them. These balls enable smooth, low-friction rotation while supporting various load types. The integration of the gear teeth simplifies the overall system design, making them a good choice for engineers seeking a more streamlined approach.

Benefits:

Maximized Space Utilization:  Placing the gear teeth on the outside allows for a larger gear diameter than an internal gear design with the same bearing size. This larger diameter translates to a higher gear ratio, which can be advantageous. Simplified Inspection and Maintenance:  External gear teeth are readily accessible for visual inspection and maintenance. This allows for easier detection of potential wear or damage, facilitating preventative maintenance and reducing the risk of unexpected downtime. Potentially Higher Strength:  External gear designs offer slightly improved strength compared to internal gear variants. This is because the outer ring of a slewing bearing is typically thicker and more robust than the inner ring, potentially allowing for a stronger gear tooth profile. Reduced Gear Stress:  The larger diameter of the external gear can distribute the load more effectively, reducing stress on the gear teeth. This can contribute to longer gear life and improved overall bearing durability.
