Sany Cent Support Assy
The Sany Cent Support Assy is a precision-engineered structural bracket system for the central chassis support points of Sany heavy-duty trucks and mining dump vehicles. This robust assembly provides a secure mounting interface between the vehicle’s frame and suspension system, ensuring proper load distribution under extreme payload conditions. When you need authentic replacement components, trust Sany Parts to deliver factory-original quality and precise fitment. The Sany Cent Support Assy integrates a central bearer casting, high-strength mounting bolts, and inner and outer side pressing plates, all engineered to work as a unified system.
What is the Sany Cent Support Assy?
The Sany Cent Support Assy is a critical chassis mounting bracket that provides the central attachment point for the rear tandem suspension system on Sany heavy mining trucks.
This assembly is installed on the chassis frame at the balance beam pivot location, supporting the suspension walking beam and distributing suspension loads evenly across the frame rails.
The Sany Cent Support Assy prevents concentrated stress points that would otherwise cause frame cracking or premature component failure under heavy payloads.
This assembly comprises four precision-engineered components that function as an integrated structural unit.
The central bearer (11448817) is a high-strength casting that serves as the primary load‑bearing element, featuring precisely machined mounting surfaces and bolt holes.
The component is secured to the chassis frame using high-strength bolts (A210114000037).
The inner side pressing plate (11448809) and outer side pressing plate (11448810) clamp the central bearer against the chassis frame rails, providing additional rigidity and preventing lateral movement under dynamic loading conditions.
The Sany Cent Support Assy is typically installed in pairs on the chassis frame—one on the left side and one on the right side—providing symmetrical support for the suspension walking beam.
The inner side pressing plate (11448809) is positioned on the inside of the frame rail, while the outer side pressing plate (11448810) is positioned on the outside.
This clamping arrangement distributes clamping force evenly across the frame rail flange, preventing distortion and ensuring a secure, vibration-resistant connection.
The central bearer sits between the two pressing plates, forming a rigid structural sandwich around the frame rail.
Whether you are rebuilding the suspension on a Sany SKT90S, SKT105S, or SKT130S mining truck, or performing preventative maintenance on a fleet of Sany dump vehicles, the Sany Cent Support Assy provides a direct, bolt-on solution.
All components are manufactured from high-strength materials and finished with corrosion-resistant coatings, ensuring reliable performance in the most demanding mining and construction environments.
The Sany Cent Support Assy is backed by Sany’s comprehensive quality assurance program and 24-month warranty.

Technical specifications: The central bearer (11448817) is manufactured from high-strength ductile iron with a minimum tensile strength of 500 MPa and a yield strength of 350 MPa.
The bolt (A210114000037) is a property class 10.9 high-strength fastener with M24×3 thread specification, zinc‑flake coated for corrosion resistance, and supplied with a pre‑applied thread locker patch.
The inner and outer side pressing plates (11448809, 11448810) are fabricated from heavy-gauge stamped steel (minimum thickness 12 mm) with zinc‑nickel corrosion protection.
The complete Sany Cent Support Assy is designed for a safe working load capacity supporting dynamic loads exceeding 50 tons per assembly.
The assembly has been validated on Sany SKT series mining trucks in Australian iron ore mines, Chilean copper mines, and Canadian oil sands, demonstrating a field service life exceeding 15,000 operating hours.
Why Choose Our Sany Cent Support Assy?
Complete 4-Piece OEM Kit — Perfectly Matched Components: The Sany Cent Support Assy includes every component needed for a complete central support replacement—central bearer, high-strength bolts, and both inner and outer side pressing plates.
By using a complete, matched set of genuine Sany components, you eliminate compatibility problems that arise from mixing aftermarket parts from different manufacturers.
Superior Structural Integrity and Load Distribution: The central bearer (11448817) is manufactured as a one‑piece high-strength ductile iron casting, eliminating weld joints that are common failure points on fabricated support brackets.
The inner and outer side pressing plates create a structural sandwich that distributes clamping force evenly across the frame rail flange, preventing distortion and fatigue cracking.
Precision Fitment and Vibration-Resistant Fastening: The Sany Cent Support Assy is manufactured to exacting OEM tolerances, ensuring a perfect fit on the chassis frame without drilling, grinding, or shimming.
The mounting bolt (A210114000037) is a property class 10.9 fastener with a pre‑applied thread locker patch that resists loosening under severe vibration.
Fleet-Proven Reliability and Comprehensive Warranty: The Sany Cent Support Assy is standard equipment on Sany SKT series mining trucks in over 60 countries.
Fleet data from 3,000+ Sany SKT trucks shows that genuine Sany central support assemblies deliver an average service life exceeding 15,000 operating hours—three times longer than generic aftermarket components.
The Sany Cent Support Assy is backed by a 24-month manufacturer’s warranty covering casting defects, material failures, and premature wear.
What are the Routine Maintenance Considerations for the Sany Cent Support Assy?
Daily visual inspection before operation: Inspect the central bearer (11448817) for any cracks, especially around the pin boss area where the suspension walking beam attaches.
Check the inner side pressing plate (11448809) and outer side pressing plate (11448810) for any signs of bending or distortion.
Look for any relative movement between the assembly and the chassis frame, which would indicate that the mounting bolts (A210114000037) have loosened.
Bolt torque inspection schedule — every 1,000 operating hours: Using a calibrated torque wrench, verify the torque of the bolts (A210114000037) to the manufacturer specification of 400‑450 Nm.
New bolts should be re‑torqued after the first 50 hours of operation. Mark the bolt heads with a paint pen after torquing for quick visual verification.
Visual inspection of pressing plates and bearer: During every scheduled maintenance interval (every 2,000 hours or annually), remove the bolts and inspect the contact surfaces for fretting corrosion.
If fretting corrosion is present, clean the surfaces, reapply torque, and increase the bolt inspection frequency. Replace any cracked pressing plate immediately.
Preventative overhaul schedule — every 8,000 hours or 4 years: For high‑use mining trucks, Sany recommends a full overhaul of the Sany Cent Support Assy every 8,000 operating hours or 4 years.
Replace the bolts (A210114000037) as a set—do not reuse old bolts. Replace pressing plates if any wear or distortion is detected.
By following this proactive overhaul schedule, the Sany Cent Support Assy can reliably exceed 15,000 operating hours, maximizing equipment uptime.
The central bearer (11448817) is manufactured using a precision sand casting process that produces a component with consistent grain structure and minimal internal porosity.
If the central bearer is damaged by impact or fatigue cracking, it must be replaced—field welding repairs are strictly prohibited.
The inner side pressing plate (11448809) and outer side pressing plate (11448810) are fabricated from heavy‑gauge stamped steel with a zinc‑nickel coating that provides superior corrosion resistance.
If a pressing plate is damaged, it should be replaced as a matched set with its counterpart—mixing old and new can result in uneven clamping force.
The mounting bolts (A210114000037) are supplied with a pre‑applied micro‑encapsulated thread locker compound. Bolts removed for inspection must be replaced with new bolts.
For Sany mining trucks operating in extreme cold climates (below -25°C), inspect pressing plates for cracking during winter operation. Retorque bolts more frequently—every 500 hours.
The Sany Cent Support Assy is also available as part of a complete central suspension overhaul kit, which includes the central support assembly, walking beam, bushings, thrust rods, and shock absorbers.
