Premium XCMG Crane Swing Ring | Heavy-Duty Slewing Bearing Manufacturer
As a specialized manufacturer of slewing bearings, we understand that the XCMG crane swing ring is not just a component; it is the critical pivot point that determines the stability and safety of your lifting operations. Our replacement swing rings are engineered to meet and exceed OEM specifications, ensuring seamless compatibility with XCMG all-terrain, rough-terrain, and truck cranes.
We provide high-precision rotary solutions designed to withstand extreme loads, shock vibrations, and harsh environmental conditions.
🏗️ Product Overview: Engineered for XCMG Compatibility
Our XCMG crane swing ring (slewing bearing) is designed to replace original equipment manufacturer parts with precision. Whether you are maintaining an XCMG QY series truck crane or a large-scale all-terrain crane, our bearings provide the rotational accuracy and structural integrity required for heavy lifting.
We utilize advanced heat treatment processes and high-grade steel to ensure that every swing ring delivers superior resistance to wear and deformation. By choosing our aftermarket solutions, you secure a cost-effective alternative to OEM parts without compromising on performance or safety margins.
🛡️ Performance & Quality Assurance
To ensure maximum uptime for your machinery, our XCMG compatible swing rings undergo rigorous quality control. We focus on three core performance pillars:
-
High Load Capacity: Designed to simultaneously withstand large axial forces, radial forces, and tilting moments. This is crucial for the dynamic movements of XCMG cranes during lifting operations.
-
Precision Gearing: We manufacture both internal and external gear options with high-precision hobbing and grinding processes. This ensures smooth meshing with the pinion, reducing backlash and ensuring precise rotation control.
-
Durability in Harsh Conditions: Our bearings feature specialized sealing strips (often multi-lip seals) that prevent grease leakage and block contaminants like dust, mud, and moisture. This is essential for construction sites and mining operations.
Quality Control Process:
-
Material Selection: Use of vacuum-degassed steel (e.g., 42CrMo, 50Mn) to reduce impurities.
-
Heat Treatment: Induction hardening of raceways to achieve optimal hardness (HRC 55-62) while maintaining a tough core.
-
Precision Grinding: Final grinding of raceways to ensure geometric accuracy and smooth rotation.

❓ Frequently Asked Questions (FAQ)
Q1: How do I identify the correct swing ring for my XCMG crane?
A: You can identify the part by checking the nameplate on the old bearing, looking for the OEM part number, or by measuring the bolt hole circle diameter (PCD), the number of teeth, and the module of the gear. Sending us a photo of the nameplate or a dimension sketch is the most accurate method.
Q2: What is the lead time for an XCMG crane swing ring?
A: For standard models (such as common 01-series or 02-series bearings), we often have stock or can ship within 7-15 days. For large-diameter or custom-made bearings, the production time is typically 30-60 days.
Q3: Do you provide warranty on these bearings?
A: Yes, we provide a standard warranty (typically 12 months) covering manufacturing defects in material and workmanship. We also offer technical support for the lifetime of the product.
Q4: Can I use your bearing if the original XCMG gear is worn out?
A: Absolutely. We recommend replacing both the swing ring and the pinion gear simultaneously to ensure proper meshing and prevent premature wear on the new bearing.
