As a core critical component for heavy construction machinery, it is designed to meet the stringent performance requirements of industrial business clients, including heavy machinery manufacturers, infrastructure project contractors, and professional equipment maintenance service providers.

Technical Specifications & Dimensional Parameters

Key Features & Performance Advantages

This 200-ton excavator slewing ring integrates industry-leading design and precision manufacturing to deliver unmatched performance for heavy excavation operations.

High-Precision Three-Row Roller Structure: The dedicated three-row cylindrical roller design provides superior axial, radial, and tilting moment load capacity, perfectly matching the extreme load demands of 200-ton ultra-large excavators.

Full-Surface Precision Grinding: All raceway surfaces, connecting surfaces, and mounting surfaces undergo precision grinding processing, which effectively reduces operational vibration, enhances equipment rotational stability, and minimizes wear during long-term heavy-load operation.

FEA-Optimized Rolling Element Geometry: Through finite element analysis and dynamic simulation, we optimize the geometric structure of rolling elements based on real load stress distribution under working conditions, significantly improving the load distribution uniformity and impact resistance of the heavy-duty excavator slewing bearing.

Custom-Engineered Cage Design: The specially developed cage ensures smooth and effective rotation of rolling elements, greatly reduces sliding friction during operation, lowers heat generation, and extends the overall service life of the slewing ring.

Applications & Compatible Equipment

The 134.50.2840 slewing bearing is primarily designed for 200-ton class heavy construction excavators, with full compatibility for mainstream OEM 200-ton excavator models. Its robust performance also makes it suitable for other heavy earthmoving and construction machinery, including large mining excavators, heavy-duty digging equipment, large-scale earthmoving machinery, and foundation construction equipment used in highway, railway, and water conservancy projects.

Installation, Operation & Maintenance Guidelines

To ensure optimal performance and maximum service life of your excavator slewing ring, we provide standardized guidelines for industrial business clients:

Pre-installation: Inspect the slewing ring for any transport damage, confirm the flatness of the mounting base, and clean all contact surfaces thoroughly.

Installation: Align the mounting holes accurately, tighten the bolts in a diagonal sequence with specified torque, and complete coaxiality calibration to avoid eccentric load.

Operation: Avoid overloading beyond the rated load range, and prohibit sudden impact loads during full-swing operation.

Maintenance: Perform regular lubrication with specified grease at the recommended interval, conduct monthly inspections of raceway wear and bolt tightness, and complete annual comprehensive performance testing.
