Premium XCMG Excavator Swing Bearing | OEM Quality Slewing Ring Replacement
Product Overview
As a professional rotary bearing manufacturer, we specialize in producing high-precision slewing bearings tailored for heavy-duty construction machinery. Our XCMG Excavator Swing Bearing is engineered to meet the rigorous demands of excavation operations, serving as the critical "joint" of the machine.
This component allows the upper structure of the excavator to rotate smoothly relative to the undercarriage while simultaneously supporting immense axial, radial, and tilting moment loads. Designed as a direct OEM replacement, our swing bearing ensures seamless compatibility with XCMG excavator models, delivering the durability and stability required for mining, infrastructure, and earthmoving projects.
Performance and Quality Highlights
We understand that downtime is costly. Therefore, our manufacturing process focuses on longevity and reliability.
-
Robust Load Capacity: Engineered to withstand complex combined loads. Whether it's the digging force or the weight of the load, our bearing maintains stability.
-
Precision Gearing: The internal or external teeth are precision-cut and induction-hardened to ensure smooth meshing with the swing motor pinion, reducing wear and noise during rotation.
-
Superior Sealing: Equipped with high-quality rubber seals (often double-lipped) to prevent the ingress of dust, mud, and water—common hazards in excavation sites—while retaining lubrication.
-
Heat-Treated Raceways: The raceways undergo specialized heat treatment to increase surface hardness, significantly extending the service life of the rolling elements (balls or rollers).

Frequently Asked Questions (FAQ)
Q1: How do I identify the correct swing bearing for my XCMG excavator?
A: You should check the nameplate on your current bearing or the excavator's parts manual. Key identifiers include the number of gear teeth, the bolt hole pattern (PCD), and the overall dimensions (outer/inner diameter).
Q2: Do you supply bearings for older XCMG models?
A: Yes, as a manufacturer, we can produce bearings for both current and legacy XCMG excavator models. Please provide the machine model and year of manufacture.
Q3: What is the lead time for production?
A: For standard models, we often have stock available for immediate shipment. For custom or large batch orders, the typical lead time is 15-30 days.
Q4: Can I get a sample for testing?
A: We welcome sample orders for quality testing. Please contact our sales team for sample availability and pricing.
