China External tooth L-type single-row ball-type slewing bearing Supplier, Factories

The gears are machined on the outer circumference of the outer ring. This is the most common and mainstream tooth configuration for L-type bearings. The driving small gear meshes with the outer teeth of the outer ring, driving the outer ring (usually connected to the rotating platform) to rotate. While providing a strong anti-overturning moment capacity, it integrates a convenient direct drive interface for maintenance. 

Product Description

Advantages
Best overall performance

Perfectly combines the high torque capacity of the L-type design and the convenience of the external gear drive.

Excellent maintainability

The gear meshing condition and lubrication status are clearly visible, making it easy to adjust the gap and replace the small gear.

Direct torque transmission

The small gear drives the outer ring to rotate, with a large force arm, resulting in a relatively reasonable torque demand for the drive.

Typical Applications
  • Medium to heavy-duty excavators: Perfectly handle the huge overturning moment required for excavation.
  • Tractor-mounted cranes, marine cranes: Maintain stability when lifting heavy loads.
  • Various engineering machinery slewing platforms with large booms.
  • Port machinery (such as small cranes).
Frequently Asked Questions

What are the key design features that ensure high performance?

The product achieves the best overall performance by perfectly combining the high torque capacity of the L-type design with the convenience of an external gear drive.

Why is this drive easy to maintain?

It offers excellent maintainability because the gear meshing condition and lubrication status are clearly visible, which makes adjusting the gap and replacing the small gear simple and straightforward.

How does the torque transmission system work efficiently?

The small gear drives the outer ring to rotate using a large force arm. This results in direct torque transmission and a highly reasonable torque demand for the drive system.

Is this product suitable for heavy excavators?

Yes, it is designed for medium to heavy-duty excavators and can perfectly handle the massive overturning moment required during excavation operations.

What types of crane applications can use this system?

It is highly suitable for tractor-mounted cranes, marine cranes (helping maintain stability under heavy loads), and small cranes used in port machinery.

Can it be used on other engineering machinery slewing platforms?

Absolutely. It is compatible with various engineering machinery slewing platforms equipped with large booms.
