ODT007874054 Articulation Frame Bearing Carrier Assembly for Sany SAT40C
The ODT007874054 Articulation Frame Assembly is the primary bearing carrier and housing assembly situated within the central hitch system of the Sany SAT40C articulated dump truck. Articulated dump trucks operate under continuous, heavy loads, generating massive torsional torque across their drivetrain axles [1]. The articulation frame component (ODT007839632) serves as the primary structural housing block that mounts the central oscillation shaft and houses the heavy-duty bearings. It permits independent rolling oscillation between the tractor and trailer, ensuring all six wheels stay firmly on the ground while traversing rugged off-road mining ruts.
This structural assembly houses the high-strength Articulation Frame Shaft (ODT005797300), a high-precision cylindrical NSK Bearing NJ2214C3 (B221500000200), and dual spherical Joint Bearings (60230461) to handle heavy radial and axial loads. It incorporates four heavy-duty BAUMSLX7 Oil Seals (151402010311B) and dual O-rings to prevent grease leakage and isolate the high-precision bearings from coal dust, sand, and water. A total of twenty-four adjustable shims (items 11, 12, 13, and 14) are included to allow mechanics to calibrate bearing pre-load precisely during assembly. We supply the fully integrated ODT007874054 frame assembly as well as individual shafts, NSK bearings, spherical joint bearings, BAUMSLX7 rotary seals, and pre-cut shims. Both genuine Sany OEM kits and highly reliable aftermarket options are in stock for rapid international shipping.

Features & Benefits of Our Articulation Frame Assembly
- High-Strength Cast Bearing Housing: The Articulation Frame Component (ODT007839632) is cast from premium structural-grade, low-alloy steel plate, designed to bear high engine and cab loads under severe mine-haulage forces.
- Premium NSK Cylindrical Roller Bearing: Features a high-precision NSK Cylindrical Roller Bearing (B221500000200 / NJ2214C3) engineered to support the central oscillation shaft under continuous radial loads, ensuring low friction and thermal stability.
- Multi-Directional Spherical Joint Bearings: Includes dual Joint Bearings (60230461) designed to support multi-angle steering and oscillation movements, reducing local stress concentration on the connecting shafts.
- Extreme Environment Sealing: Equipped with four premium BAUMSLX7 Oil Seals (151402010311B) and specialized O-rings to block out highly abrasive mine dust, mud, and water, preserving internal bearing life.
- Precise Bearing Pre-load Calibration: The package includes twenty-four specialized shims (items 11, 12, 13, & 14) of varied thicknesses. These enable maintenance technicians to calibrate bearing play precisely, eliminating high-frequency drivetrain and chassis vibrations.
Ordering & Technical Maintenance Guidelines
- Calibrate Bearing Pre-Load on Reassembly: When overhauling the central joint housing, the tapered roller bearings must be pre-loaded correctly. Utilizing the adjustable shim plates (items 11, 12, 13, & 14) prevents joint binding (if too ti
