That’s why an internal gear slewing ring is often the preferred solution for the upper structure rotation mechanism. It allows for compact design while maintaining strength, precision, and long-term performance. At ZZ, we manufacture internal gear slewing rings specifically designed for use in compact and mini excavators, offering both standard models and OEM custom options. Why Use Internal Gear Slewing Bearings? To begin with, internal gear configurations provide better protection from external elements, such as mud, sand, and debris — which are common in excavation environments. Additionally, the internal gear design results in a cleaner profile and fewer exposed components, reducing the risk of gear wear. Moreover, it allows for tight radius installation, saving space and improving integration with hydraulic motor drives. Typical applications include: Mini & compact excavators (1–10 ton) Skid-steer excavators Urban utility and landscaping machines Remote-controlled demolition equipment Key Features: Outer diameter: 400mm–1200mm Gear type: internal module gears (DIN 3967 compliant) Load support: axial, radial, and tilting High-strength forged steel structure Optional corrosion-resistant coatings (for humid regions) ZZ ensures every slewing ring goes through hardening and precision grinding to guarantee long service life, even under constant pivoting and vibration. Real Case Example A European excavator OEM required a 620mm internal gear slewing ring for a 3.5-ton tracked excavator. We provided a double-sealed, grease-filled unit with precision-cut teeth, helping them reduce noise and backlash while increasing durability. How to Order Simply share: Excavator model and tonnage Desired gear module and number of teeth Load specs and application type We’ll recommend the best-fit slewing ring and send a quote within 24 hours.

Why Use Internal Gear Slewing Bearings?

To begin with, internal gear configurations provide better protection from external elements, such as mud, sand, and debris — which are common in excavation environments.

Additionally, the internal gear design results in a cleaner profile and fewer exposed components, reducing the risk of gear wear.
Moreover, it allows for tight radius installation, saving space and improving integration with hydraulic motor drives.

Typical applications include:

  • Mini & compact excavators (1–10 ton)
  • Skid-steer excavators
  • Urban utility and landscaping machines
  • Remote-controlled demolition equipment

Key Features:

  • Outer diameter: 400mm–1200mm
  • Gear type: internal module gears (DIN 3967 compliant)
  • Load support: axial, radial, and tilting
  • High-strength forged steel structure
  • Optional corrosion-resistant coatings (for humid regions)

ZZ ensures every slewing ring goes through hardening and precision grinding to guarantee long service life, even under constant pivoting and vibration.

Real Case Example

A European excavator OEM required a 620mm internal gear slewing ring for a 3.5-ton tracked excavator. We provided a double-sealed, grease-filled unit with precision-cut teeth, helping them reduce noise and backlash while increasing durability.

How to Order

Simply share:

  • Excavator model and tonnage
  • Desired gear module and number of teeth
  • Load specs and application type

We’ll recommend the best-fit slewing ring and send a quote within 24 hours.
