High-Performance Slewing Bearings for Aerial Work Platforms (AWP)
Precision Engineering for Elevated Safety and Stability
As a premier manufacturer specializing in slewing drive solutions, we understand that the Aerial Work Platform (AWP) industry demands uncompromising reliability. Our slewing bearings are the critical "joints" that empower scissor lifts, boom lifts, and vertical mast lifts to operate with precision at extreme heights.
Designed to withstand harsh outdoor environments and heavy dynamic loads, our AWP slewing bearings ensure 360-degree smooth rotation, enabling operators to reach difficult work areas safely. Whether for construction, maintenance, or industrial applications, our bearings provide the structural integrity required for modern aerial access equipment.
Product Performance & Quality Assurance
Our manufacturing philosophy centers on durability and load-bearing capacity. We utilize advanced heat treatment technologies and high-grade alloys to produce bearings that outperform industry standards.
Key Performance Features
-
Integrated Gear Design: Our internal or external gear options are precision-cut to mesh perfectly with hydraulic or electric drive motors, ensuring synchronized rotation without slippage.
-
Compact & Lightweight Structure: By optimizing the raceway geometry, we achieve high load capacity in a compact envelope, allowing AWP manufacturers to maximize payload without increasing machine weight.
-
Corrosion Resistance: Standard models feature high-strength steel with specialized coatings, while our marine-grade options utilize stainless steel or zinc-nickel plating to resist rust in coastal or humid construction sites.
-
Low Friction & Maintenance-Free: Pre-lubricated with high-viscosity grease and sealed with durable rubber strips (IP67 rated), our bearings minimize friction and prevent contaminant ingress (dust, water, mud).
Material & Heat Treatment
-
Material: 42CrMo, 50Mn, or 40Cr (High-strength alloy steel).
-
Hardness: Raceway hardness reaches HRC 55-62 via induction hardening, ensuring resistance to deformation under heavy impact loads.

Frequently Asked Questions (FAQ)
Q1: What is the difference between a single-row and double-row slewing bearing for an AWP?
A: Single-row four-point contact ball bearings are generally used for lighter to medium loads and offer a more compact design. Double-row ball bearings or crossed roller bearings are chosen for heavier loads and higher tilting moments, providing greater rigidity for large boom lifts.
Q2: Can you manufacture bearings with specific gear modules?
A: Yes. We have advanced gear hobbing and shaping machines. We can manufacture internal or external gears with specific modules (m), pressure angles, and tooth counts to match your drive pinion.
Q3: How do you ensure the bearing won't rust outdoors?
A: We apply a multi-layer protection system. This includes phosphate coating (black oxide) followed by anti-rust oil. For harsh environments, we offer Dacromet or Geomet coatings, which provide superior salt-spray resistance (up to 500+ hours).
Q4: What is your lead time for standard AWP bearings?
A: For standard models, we often have stock or can ship within 15-20 days. Customized orders typically take 30-45 days depending on quantity.
Q5: Do you provide installation bolts?
A: While the bearing usually comes with mounting holes prepared, high-strength installation bolts (Grade 10.9 or 12.9) are typically supplied by the AWP manufacturer to ensure the correct clamping force for the specific machine assembly.
