Emergency Replacement of Slewing Bearings：LDB Bearing’s Stock & Service

When mission-critical equipment grinds to a halt due to a failed Slewing Bearings, every minute counts. Downtime isn’t just an inconvenience; it’s a direct drain on productivity, profitability, and project timelines. At LDB Bearing, we operate on a simple, unwavering principle: Your emergency is our priority. That’s why we maintain one of the industry’s most extensive and strategically managed inventories of pre-engineered slewing rings, ready for immediate deployment to get your operations back online with minimum delay.

We recognize that industries like mining, heavy construction, port logistics, and energy generation cannot afford to wait weeks or months for a custom-manufactured bearing. The clock is always ticking. Our Emergency Response Slewing Ring Program is engineered specifically for this scenario, offering a robust selection of the most in-demand sizes, types, and models for same-day or next-day dispatch to destinations worldwide.

The LDB Bearing Emergency Stock Advantage: Speed Meets Precision

Our emergency stock is not merely a collection of standard parts; it is a carefully curated inventory based on decades of field data and failure analysis. We stock the components most likely to be needed for urgent replacements across a vast array of machinery.

Our readily available stock includes:

• Gear Types: External gear, internal gear, and non-geared (smooth) versions.
• Structural Types & Load Capacities:
  • Single-Row Four-Point Contact Ball Bearings: The versatile workhorse for applications requiring a compact design that can handle combined axial, radial, and moment loads. Ideal for mobile cranes, excavators, and rotary platforms. (Axial Load Capacity: Up to 800 kN)
  • Double-Row Ball Slewing Bearings: For higher load demands and greater rigidity, offering superior performance in applications like stacker-reclaimers and larger aerial work platforms. (Axial Load Capacity: Up to 1,500 kN)
  • Crossed Cylindrical Roller Bearings: The premier choice for applications demanding extreme precision, high rigidity, and minimal rotational friction, such as robotic welding positioners and precision index tables. (Axial Load Capacity: Up to 1,200 kN)
• Size Ranges:
  • Outer Diameter (OD): From a compact 400 mm to a substantial 2,000 mm.
  • Cross-Section: Ranging from 50 mm to 120 mm, catering to various structural constraints.
• Material & Manufacturing Standards: Every in-stock bearing is manufactured from certified 42CrMo4 or 50Mn high-strength alloy steel. The raceways are induction hardened to a depth of 55-60 HRC, ensuring exceptional wear resistance and fatigue life. All units conform to ISO 9001:2015 quality management standards and are engineered to meet or exceed DIN, ABEC, and other relevant international specifications.

Guaranteed Compatibility with Major OEM Machinery

A critical factor in a swift replacement is guaranteed compatibility. Our inventory is meticulously mapped to ensure direct interchangeability with common and critical models from leading global OEMs, including but not limited to:

• Excavators & Mining Shovels: Komatsu, Caterpillar, Hitachi, Liebherr, Volvo
• Mobile & Crawler Cranes: Terex, Tadano, Demag, SANY, Zoomlion
• Aerial Work Platforms (AWPs): JLG, Genie, Skyjack, Haulotte
• Construction & Earthmoving: Bobcat, Doosan, Case
• Wind Turbine Yaw & Pitch Systems: For critical maintenance and repair operations.

Each bearing in our stock is cross-referenced with OEM part numbers. If you provide the machine model and the original part number, we can often confirm compatibility within the hour.

Value-Added Ready-to-Ship Specifications

To ensure a true “plug-and-play” experience, every emergency stock slewing ring from LDB is delivered ready for installation:

• Pre-lubrication: Filled with high-performance, extreme-pressure (EP) lithium complex grease suitable for a wide range of operating temperatures.
• Integrated Sealing: Equipped with durable, multi-lip NBR or wear-resistant polyurethane seals to protect the raceway from contamination from day one.
• Mounting Hardware: All units come with pre-drilled and tapped mounting holes. High-strength, grade 10.9 or 12.9 mounting bolt kits are available as an optional, add-on item for ultimate convenience.
• Surface Protection: Coated with an anti-corrosive storage lubricant to prevent rust during transit and storage.

Express Customization: When a Perfect Match is Not in Stock

We understand that sometimes a perfect match may not be sitting on our shelf. In such cases, our Rapid Modification Service provides a swift alternative to full custom manufacturing.

• Custom Bore & Hole Machining: We can often modify the internal diameter (ID) or mounting hole pattern of an in-stock unit to fit your specific requirements. This service can turn a near-match into a perfect fit within 24-72 hours.
• Special Seal & Lubrication Kits: For extreme environments (e.g., high-temperature, chemically exposed, or marine applications), we can provide and install specialized seal kits or high-performance greases.

Industries and Applications We Serve in Crisis

Our emergency stock is strategically selected to support the most downtime-sensitive industries:

• Heavy Construction & Mining: Excavators, shovels, draglines, concrete pump trucks.
• Material Handling & Logistics: Port cranes, container handlers, stacker-reclaimers, automated guided vehicles (AGVs).
• Energy Sector: Wind turbine repair (yaw and pitch systems), hydraulic power generation equipment.
• Aerospace & Defense: Radar antenna pedestals, missile launch systems, turret platforms.
• Manufacturing & Robotics: Heavy-duty welding positioners, palletizers, large rotary indexing tables.
• Marine & Offshore: Deck cranes, winches, propulsion systems.
